-
GPS Receiver Module: 1023141.1 0702 REV.1
-
Product Type: GPS Receiver Module
Overview
This is a GPS receiver module designed as an internal component for the Antenna Unit of the Nera F33 satellite terminal. The Nera F33 is a maritime communications system that provides voice, fax, and medium-speed data services via the Inmarsat satellite network.
Key Information
-
Primary Function: The GPS module is an integral part of the antenna unit, providing location data that is essential for the antenna’s initial satellite search and stabilization processes. The antenna uses this GPS information to calculate its position and find the correct satellite signal.
-
Primary Source: The internal GPS receiver located within the Antenna Unit is the primary positioning source for the Nera F33 system. It can also be configured to use an external GPS source as a backup if needed.
-
Installation Context: This module is housed inside the Nera F33 Antenna Unit, which is typically mounted on a mast or tower. The antenna unit includes a servo-stabilized dish, an RF-Transceiver, and a protective radome. Proper installation is critical, requiring a clear line of sight to the satellite and avoidance of interference from other equipment like radar or VHF antennas.
