ECS (USA)

An Electronic Chart System (ECS) is a navigational information system designed to support safe and efficient marine navigation through the display of official electronic navigational charts (ENCs) and sensor data.

TZ Professional v5.3 with the S57/S63 chart module, is certified as an RTCM Class B Electronic Chart System and conforms to RTCM Standard 10900.8 for Electronic Chart Systems (ECS).

For vessels operating outside the boundary line defined in 46 CFR Part 7, the ECS installation must comply with IEC 60945 Sections 9 and 10. This requirement is met by installing TZ Professional on tested and approved marine computer hardware, including selected Hatteland and Seatronx systems below:

- Hatteland: HT B40G-i5-MP-A751212, HT B40-i7-MP-A751213, HD 16T36 MMC-MGG-5WPJAA, HD 21T36 MMC-MGG-5WPJAA, HD 24T36 MMC-MGG-5WPJAA, HD 27T36 MMC-MGG-5WP 
- Seatronx: MPC-E10-1300-S, MPPC-15T, MPPC-16T MPPC-19T, MPPC-24T, MPPC-27T 

Proper ECS certification also depends on correct system configuration. TZ Professional requires:

  • A type-approved EPFD position source in accordance with NVIC 01-16, Change 3

  • Installing the NOAA S57 charts with automatic chart updating enabled

  • Enabling the Shell (exclusive) mode operation

  • Locking of the user interface after setup

  • Adjusting the computer BIOS and user login configurations that ensure automatic restart and uninterrupted operation after power loss 

When installed, configured, and maintained according to these requirements, TZ Professional v5.3 with the S57/S63 functions as a compliant ECS solution, supporting regulatory expectations while enhancing navigational safety and operational reliability.
