APRS Payload Module
APRS (Automatic Position Reporting System) enables real-time repeat* or forward
positioning and data of ground tracking equipments, such as vehicles, animals, plants,
ranging from ecological, industrial to civil purposes and various applications.
*Real-time repeat: This optional function is disabled. The packet data real time repeater function is
determined by frequency coordination and project application.
In the figure shown on the right, the data collect function could be configurable
for repeater or store-forward to the ground station.
The APRS payload "Real Time Repeater" / "Store & Forwarding" applications are:
■ APRS - Vehicle and vessels positioning with data collection
■ APRS - Ecological & seismic / tracking & detection: birds, animals, landslides, etc.
