NavData Types

Various types of NavData can be displayed in TimeZero:

Sensors NavData

The Sensor NavData is used to display numerical values received from sensors connected to the computer. The font color is white for data that is received directly from a sensor and yellow when the data is being computed by TimeZero from a sensor:

Note: In the example, above, Speed Over Ground (SOG) is displayed in white because it is directly received from the GPS. The True Wind Speed (TWS) is displayed in yellow because it is computed by TimeZero from Apparent Wind (received from the sensor) and Speed.

The following Sensor NavData are available:

Date/Time
Boat Position
COG - Course Over Ground
SOG - Speed Over Ground
DPT - Depth

Note: The Depth can be configured to display the value below the keel or below sea level using the "Depth Display" from the Initial Setup Options

SST - Sea Surface Temperature
HDG - Boat Heading (can be computed by TimeZero from SOG when the speed is over 1kn)
STW - Speed Through Water (also known as Speed Over Water)
Set - Current Direction (can be computed by TimeZero from COG, STW, Heading and SOG)
Drift - Current Speed (can be computed by TimeZero from COG, STW, Heading and SOG)
TWD - True Wind Direction. If True Wind Direction is not sent by the wind sensor, it can be computed by TimeZero from Apparent Wind Angle with Heading/Speed through Water ("Surface" reference) or COG/SOG ("Ground" Reference). "Surface" or "Ground" can be selected from the Initial Setup Options ("True Wind and VMG Calculation")
TWA - True Wind Angle. If True Wind Angle is not sent by the wind sensor, it can be computed by TimeZero from Apparent Wind Angle with Heading/Speed through Water ("Surface" reference) or COG/SOG ("Ground" Reference). "Surface" or "Ground" can be selected from the Initial Setup Options ("True Wind and VMG Calculation")
TWS - True Wind Speed. If True Wind Speed is not sent by the wind sensor, it can be computed by TimeZero from Apparent Wind Speed and Speed through Water ("Surface" reference) or SOG ("Ground" Reference). "Surface" or "Ground" can be selected from the Initial Setup Options ("True Wind and VMG Calculation")
AWA - Apparent Wind Angle
AWS - Apparent Wind Speed
VMG - Velocity Made Good. If VMG is not received, it can be computed by TimeZero from True Wind Direction and Speed through Water ("Surface" reference) or SOG ("Ground" Reference). "Surface" or "Ground" can be selected from the Initial Setup Options ("True Wind and VMG Calculation").

To change the data displayed in a sensor NavData, just right click and select a new data from the contextual menu. The NavData will be immediately updated and display the selected data.

It is possible to configure one NavData to cycle through multiple data. Just right click on the NavData, select "Add" and choose the data you want to add. The NavData will begin to cycle between the two data. You can repeat this operation and add more data to cycle through. To stop the cycle, uncheck all data from the "add" contextual menu.

Note: The cycle speed can be changed from the General Options by adjusting the "NavData Multi Data Dwell Time" setting.

Route NavData

Route NavData are used to display various numerical values linked to the Active Route computed by TimeZero. Note that by default an "Active Route NavData" giving you basic information about the active route is configured inside the "Navigation" NavData panel. If that does not give you enough information, Route NavData can be configured manually. Note that if a route or Go To is not activated, the Route NavData will display dashes ("--"). The font color of the Route NavData is red:

The following Route NavData are available:

BTW - Bearing to Waypoint: indicates the course to steer to reach the active Waypoint from own ship position. This value does not take into account any current and is simply the course as it would be plotted on a chart. This value corresponds to the "CTS" column in the list.
HTS - Heading to Steer (real time): indicates the course to steer to reach the active Waypoint from own ship position taking into account the real time variations caused by wind and/or currents. The HTS (real time) is computed by TimeZero from the CTS and the drift vector.
HTS - Heading to Steer: indicates the course to steer to reach the active Waypoint from own ship position taking into account the Tidal Currents embedded in TimeZero.

Note: The HTS will display the same value as CTS if there is no Tidal Currents near the Active Leg.

NEXT - Next Course: indicates the CTS to follow after the next Waypoint. This is useful to see if a major course change is needed after passing the Active Waypoint.
TTG - Time To Go (using VMC): indicates the time that it will take to reach the Active Waypoint. TimeZero computes this value using the DTW and the VMC.
DTW - Distance To Waypoint: indicates the distance remaining to reach the Active Waypoint from own ship position.
XTE - Cross Track Error: indicates the distance the vessel is to one side of the straight line between the Active Waypoint and previous Waypoint (or position where the route was Activated if the Active Waypoint is the first of a route or a Go To).
ETA - Estimated Time Arrival: indicates the arrival date and time taking into account the Tidal Currents along the route and the real time speed.
TTA - Time To Arrival: indicates the time remaining to reach the end of the route taking into account the Tidal Currents along the route and the real time speed.
DTA - Distance to Arrival: indicates the distance remaining to reach the end of the route.
VMC - Velocity Made good on Course: indicates the speed made towards the Active Waypoint. This is computed by TimeZero from the component of SOG that is in the direction of the Active Waypoint. In other words, the VMC is "the speed at which you approach the Active Waypoint".

To change the data displayed in a Route NavData, just right click and select a new data from the contextual menu. The NavData will be immediately updated and display the selected data.

Active Route NavData

When a route is activated, the Active Route NavData displays Distance, Time To Go and Estimated Time of Arrival of each waypoint:

If the route contains many waypoints that do not fit inside the NavData, it is possible to scroll the content of the NavData to look at future waypoint information. Note that the last waypoint (the arrival) will always be visible at the bottom of the NavData.

Note that this NavData automatically expands and contracts to occupy the remaining space of the NavData container. If you undock the NavData, a right click on it will allow you to set the size it occupies (to display 5, 10 or 15 waypoints).

You can right click on this NavData to configure its content. You can also select to only display the waypoints that have been named. This can be useful when you want to display only a couple of important waypoints in the list. In this case, simply double click on the waypoint (on the chart) to enter a name.

Waypoint NavData

The Waypoint NavData displays information about the Active Waypoint. It combines in one screen a "highway" display (also known as "Helmsman" Display), and the XTE (cross track error) and BTW (Bearing to Waypoint) values.

Gauge NavData

Gauge NavData are used to display values received from sensors connected to the computer in a graphic "gauge" type display. The font color is white for data that is received directly from a sensor and yellow when the data is being computed by TimeZero from a sensor:

The following Gauge NavData are available:

Date/Time
Bearing To Cursor
TWD - True Wind Direction. If True Wind Direction is not sent by the wind sensor, it can be computed by TimeZero from Apparent Wind Angle with Heading/Speed through Water ("Surface" reference) or COG/SOG ("Ground" Reference). "Surface" or "Ground" can be selected from the Initial Setup Options ("True Wind and VMG Calculation")
TWS - True Wind Speed. If True Wind Speed is not sent by the wind sensor, it can be computed by TimeZero from Apparent Wind Speed and Speed through Water ("Surface" reference) or SOG ("Ground" Reference). "Surface" or "Ground" can be selected from the Initial Setup Options ("True Wind and VMG Calculation")
Atmospheric Pressure
Air Temperature
COG - Course Over Ground
SOG - Speed Over Ground

DPT - Depth

Note: The Depth can be configured to display a value below the keel or below sea level using the "Depth Display" from the Initial Setup.

SST - Sea Surface Temperature
HDG - Heading (can be computed by TimeZero from SOG when the speed is over 1kn)
STW - Speed Through Water (also known as Speed Over Water)

TWA - True Wind Angle (can be computed by TimeZero from Apparent Wind and STW or Apparent Wind and SOG)
AWA - Apparent Wind Angle
AWS - Apparent Wind Speed
VMG - Velocity Made Good
Total Fuel Flow
Fuel Flow #1
Fuel Flow #2
Fuel Flow #3
Fuel Flow #4

Most of the Graphic NavData scale can be adjusted from the Initial Setup Options under "Graphic Instruments Setup".

Chart Zone NavData

The Chart Zone NavData displays various information related to the vector chart of all areas you are in. By default this information corresponds to the zones located under the boat. By clicking on the boat symbol (1) at the top right of the NavData "Chart Zone" you can switch to Cursor mode (2).

Flashing Lights NavData

The "Flashing Lights" NavData will display a list of the lighted navaids that are ahead within your field of view sorted by distance. Each item of the list will display the light name, distance and bearing. The leading side of the list will also display the color and flash according to the parameters encoded in the vector chart:

Cursor NavData

The Cursor NavData displays various information related to the cursor position on the screen:

If you right click on the Cursor NavData you can configure what information you want to display.

The following data can be displayed inside the Cursor NavData:

Position: indicates the position of the cursor on the screen using the position unit selected from the Units Options.
Position Lat/Lon (hidden by default): indicates the position of the cursor on the screen using the Lat/Lon unit.

Tips: If you set the Position Unit to Loran/TD, this data allows you to display at the same time Lat/Lon and Loran/TD for cursor position.

BRG: indicates the bearing from own ship
RNG: indicates the range from own ship
DPT: indicates the depth below cursor.
Hardness %: indicates the bottom hardness value (from 0 tp 100%) when Bottom Hardness is displayed on the chart (requires compatible sounder and PBG module)
Time to cursor (hidden by default): indicates the time it would take to reach the cursor position from own ship using the current speed.

Tide NavData

This NavData displays and updates in real time the nearest Tides information from your own ship position:

The maximum search distance for Tide Stations is 50NM. If there is no tide station within this distance, the NavData will display no information.

Note that it is possible to choose and fix the Tide Station being displayed in the NavData by selecting a Tide Station as a "Reference Station". Just right click on a Tide icon on the chart and select "Use as Reference Station". To release the reference station, you can right click on the NavData and select "Set Auto".

Tips: If you right click on the NavData you can select "Open Tide Graph", this will open the full Tide Graph for that station.

Current NavData

This NavData displays and updates in real time the nearest Current station information from your own ship position:

The maximum search distance for Current Stations is 4NM. If there is no current station within this distance, the NavData will display no information.

Note: It is not possible to fix a Tidal Current station. Currents are always automatically selected based on distance from own ship.

Tips: If you right click on the NavData you can select "Open Current Graph", this will open the full Current Graph for that station.

Weather NavData

The Weather NavData displays the weather forecast under the cursor using numerical value:

In the "Planning" WorkSpace, the time of the forecast is set by the timeline. In the "Navigation" WorkSpace, the time of the forecast is always set by computer current time.

You can right click on the NavData to add or remove specific weather data.

GPS Status NavData

The GPS Status NavData displays in large font "GPS OK" (in green), "Poor GPS" in yellow or "NO GPS" (flashing in red):

It also displays the GPS accuracy (based on HDOP ) and the number of satellites that are used to compute the position fix.

Note: In order for the accuracy to be displayed in the NavData, the HDOP must be received in TimeZero (NMEA sentence GGA or GNS or GSA or PGN129029 or PGN129539). In order for Satellites in Use to be displayed, the NMEA0183 sentence GGA or GNS must be received. The GPS Poor quality indicator is a combination of HDOP and Satellites in Use (when HDOP > 4 or Satellite in use < 4).

Laylines NavData

The "Routing Module" needs to be unlocked to access this feature

The Laylines NavData displays the Port and Starboard layline optimum Course and Distance as well as Time To Go ("time to tack").

Please refer to the Laylines chapter for more information.

Trip Odometer NavData

The Trip Odometer NavData allows you to keep track of various trip statistics:

Note that all values (except Odometer) can be reset by right clicking and select "Reset". You can also enable or disable some information by right clicking on the NavData. Like in a car, the Odometer is never reset.

Tips: if you change computer or reset to factory default, the Odometer value will go back to 0. If you press and hold the CTRL key while right clicking on the NavData, a new item "Restore Odometer Value" will appear allowing you to enter any number.

Target Information NavData

The Target NavData displays detailed information about the selected target (AIS, ARPA or DSC). To select a target, just click on it. The target will become surrounded in yellow and the information will be displayed in the Target Information NavData:

Note that once a target is selected (surrounded in yellow), you can select other objects (such as Marks or Boundaries) without affecting the target selection. Only selecting another target will change the target selection.

If you click on the "i" icon (blue icon on the top right), it will open the full target property window.

AIS and ARPA List NavData

The AIS and ARPA NavData lists display a list of AIS or ARPA targets with basic information (to fit in the NavData):

The list can be sorted by Range, CPA , TCPA or SOG when you right click on the NavData. You can also select the type of data you want to see for each target (COG/SOG and/or CPA/TCPA). Note that this NavData automatically expands and contracts to occupy the remaining space of the NavData container. If all targets cannot be displayed in the space available (more likely with the AIS list), it is possible to scroll the content of the AIS or ARPA NavData.

You can click on any item of the list and TimeZero will automatically center the chart on the corresponding target. Also, if you click on a target on the chart, it will highlight it inside the list and scroll if necessary:

If you undock the NavData, a right click on it will allow you to set the size it occupies (to display 5, 10, 15, or 20 targets).

Alarm Zone NavData

Any Boundary Area can be set as an alarm zone by right clicking on the area and selecting "Own Ship Alarm". The Alarm Zone NavData is used to display the distance to the closest alarm boundary area. TimeZero will start by raising a notification when approaching the Alarm zone (you can set the distance of th "Own Ship Alarm Zone Warning" under the Alarms Options) then raise an alarm if the boat enters the alarm zone. The NavData will reflect the notification by displaying a yellow warning sign when the boat approaches the zone and red warning sign if the boat enters the alarm zone:

Note: When the distance to the alarm zone becomes smaller than the "Own Ship Alarm Zone Warning" value, a divider line is automatically displayed from the boat icon to the closest point of the alarm zone.

Event NavData

The Event NavData allows you to quickly drop a mark under your boat with a specific icon and color. You can customize the icon and color of all the 11 events by clicking on the "i" icon available on the top right corner of the NavData:

Note that events are extremely useful when fishing. You could preset specific icons and colors having a specific meaning (good pot, medium pot, bad pot) and simply use the cursor to immediately drop a mark containing the relevant information at your current position. Note that you can also use your keyboard by pressing the 0 to 9 numerical key and the Enter key (the Enter key corresponds to the bottom right event icon while the 0 key corresponds to the bottom left).

Quick Access NavData

The Quick Access NavData allows you to assign almost any function of TimeZero to a button that can be quickly activated:

When you add a Quick Access NavData, it will be empty by default. Simply click on it to open the configuration window:

This window allows you to enter the name that will be displayed on the button, the color and the Action(s) you want to perform. You can perform virtually any action available in TimeZero. Note that you can combine (add) multiple action to the same button similar to macros! For example, you could configure a button to select 2D mode, turn OFF the Depth Shading and set the orientation mode to Head Up.

Sounder Control NavData

The Sounder Control NavData gives quick access the most sounder control: TX /STBY switch, mode button to switch between Manual/Fishing/Cruising and set the Gain HF & LF only for Manual mode:

Note: Advanced user can also add Clutter control by right clicking the Sounder NavData.

Radar Control NavData

The Radar Control NavData gives quick access to the most used radar control: Gain, Sea (STC ) & Rain (FTC ):

Tips: Click on the "A" to switch from Manual to Automatic mode for the selected parameter.

The Radar Control NavData can also display the "Tune" bar (read only). Simply right click on the NavData and add "Tune" to the NavData configuration.

Advanced Radar Control NavData

The Advanced Radar Control NavData gives quick access to the more advanced radar filters. Click on the filter value to cycle through the various mode:

You can customize the NavData by right clicking on it.

Bottom Discrimination NavData

The Furuno Sounder Module and a Furuno BBDS1 or DFF1-UHD Ethernet Sounder are required to access this feature

This NavData displays real time bottom discrimination information when TimeZero is connected to a Furuno BBDS1 or DFF1-UHD Ethernet Sounder:

The four "bar graph" display the real time probability value of having either Mud/Sand/Gravel/Rock below the transducer. The colors located on the right side of each bar indicate the color of the corresponding type if the track color is set to variable according to bottom classification (from the Ship & Tracks Options).
At the top of this NavData, TimeZero displays the name of the highest probability bottom type.

Camera NavData

This NavData displays a video feed. If the camera has Pan, Tilt, and Zoom (PTZ) capabilities, a virtual joystick will appear when you roll your cursor over the NavData:

You can change the video source of the NavData by right clicking on it.

If the camera as additional features (such as the Flir M-Series), the right click contextual menu also gives access additional commands (Scan, Home, Scene, IR/Visible switch, etc...).

For more information, please refer to the Camera NavData Chapter.

Fuel Tank Level NavData

This NavData displays the Total Fuel Level:

You can display individual tank level by right clicking on the NavData. The NickName of the Fuel Tank can be changed from the Initial Setup Options (under the "Fuel" Category).

Note: The Tank Level indicator can be used for other type of fluid than Fuel (for example grey water tank). If you are not using a specific tank for fuel, make sure to disable it from the Fuel computation in the Routes Options (uncheck "use fuel tank # in vessel computation")

Multibeam NavData

The PBG module and WASSP Module are required to access this feature

The Multibeam NavData allows you transmit and standby the WASSP DRX (with WASSP Generation 3 system), enable or disable PBG and select the PBG depth source:

When selecting "Multi" the multibeam sounder (multiple points) will be used as PBG source. When selecting "Single" the regular depth (on point) will be used as PBG source. Typically, multibeam sounders are not able to track bottom in deep water. If you also have a traditional monobeam sounder connected to TimeZero, it may make sense to switch the PBG source to "Single" in deeper water.

A status indicator (green/red) is displayed under the "Multi" and "Single" selection to show you which type of data is currently available.

User Object Filters NavData

This NavData displays your user object filters using big buttons that are easy to toggle ON and OFF. For more information on how to create User Object filters, please refer to the Filters chapter.

SeaLevel IO NavData

This NavData allows you to control and monitor relays and input status from the SeaLevel Network IO 110E and 120E.

You can right click on this NavData to select which Input and Output you want to monitor/control (up to 4 inputs and 4 outputs). You can click on the "i" icon located on the top right to configure the SeaLevel hardware and rename the inputs and outputs. For more information, please refer to the SeaLevel Network IO Chapter.

Radio Direction Finder NavData

This NavData allows you to monitor the input of the RhoTheta Radio Direction Finder. It displays the information of the last bearing that was received together with channel number, frequency, and signal level:

For more information, please refer to the Radio Direction Finder Chapter.

Simulation Mode NavData

This "NavData" is only available if TimeZero is running in simulation mode. When you start TimeZero, the message "simulation mode" appears at the top of the screen. For more information, please refer to the "Start mode" chapter.

Then add the "Simulation Mode" NavData, which lets you activate the simulation of your own ship by clicking on the arrows to increase and decrease speed and course, and move the boat icon as you wish on the chart:

Note: Click on the "i" icon in the top right-hand corner of the NavData if you want to set the boat position manually using lat/lon.
