TRIPLE-A Payload Module APRS + AIS + ADS-B
APRS (Automatic Position Reporting System) enables real-time repeat* or forward
positioning and data of ground tracking equipments, such as vehicles, animals, etc.
AIS (Automatic Identification System) receiver picks up vessels
position that use an AIS A/B channels transponder.
ADS-B (Automatic Dependent Surveillance–Broadcast)
technology which enables aircrafts to determine their position via
satellite and then broadcast it. This information can be received by
Cubesat which enables aircrafts to be tracked.
*Real-time repeat: This optional function is disabled. The packet data real time repeater function is
determined by frequency coordination and project application.
Triple-A (APRS / AIS / ADS-B) payload module effectively tracks and
collects a large number of land and sea (surface) objects, as well as collects traffic
information for commercial airliners (aerial), to achieve acquisition of
APRS/AIS/ADS-B data globally.
In the figure shown on the right, the data collect function could be configurable for
repeater or store-forward to the ground station.
The Triple-A (APRS / AIS / ADS-B) payload "Real Time Repeater"/"Store & Forwarding" applications are:
■ APRS - Vehicle and vessels positioning with data collection
■ APRS - Ecological & seismic / tracking & detection: birds, animals, landslides
■ APRS - Ocean windmills, widespread area power grid management
■ AIS - Sea surface drifts, ocean current tracking and tide wave change monitoring
■ ADS-B - Receiving Latitude, longitude, altitude and direction information with ICAO codes
■ ADS-B - Space-based flight information enables broad coverage areas compensating geographic obstacles; flexible, responsive flight data for advanced air traffic controls
