Belgium Satellite Terminal

Specifications: The SAT-101 is compact, low data rate, satellite terminal designed to operate over the INMARSAT satellites using the INMARSAT D+ protocol. With an integral GPS receiver, the SAT-101 provides low cost satellite communications for applications such as asset tracking, telematics and SCADA. Four INMARSAT satellites provide Global Coverage with each satellite covering an Ocean Region (IOR, AOR-E, AOR-W or POR). On power on or waking up, a terminal first tunes to the Bulletin Board channel which contains information on the traffic channels currently in use. From the traffic channel / service ID mapping posted on the Bulletin Board, the terminal determines on which traffic channel to expect its messages, and re-tunes to this channel. Data rate for the forward channel (to terminal) is approximately 9 user bits per second, with typical message delivery latency of about 3 minutes. Return channel (from terminal) information is returned in bursts containing up to 80 user bits of information. The data rate is approximately 10 user bits per second, with typical message delivery latency of about 30s (assuming the terminal has already synchronised to the traffic channel). The SAT-101 consists of three modules, namely: Antenna, Main module, Battery pack The terminal is designed such that the battery pack can be optionally attached to the main module.
