Thingsat :: LoRa benchmarks from cubesat
Aims
- Benchmarking LoRa links over very long distance (> 500 kms) for several frequency bands (868MHz, 2.4GHz).
- Repeating LoRa frames of ground LoRaWAN trackers (emergency usecase).
- Designing and evaluating LoRa delay-tolerant networks algorithms.
- Studying frames of ground LoRaWAN endpoints from the space.
- Synchronizing ground LoRaWAN endpoints from the space.
- Monitoring with sensors in real field cases : artic glaciers, helium containers, fish farms ...
LoRa communication payload onboard of Stork 1 mission.
The CSUG designs a LoRa communication board and antenna for cubesats. The board and the antenna are hosted by the SatRevolution's Stork mission. The board embeds one Semtech SX1302 concentrator for communications on the 863-870 MHz band and one Semtech SX1280 transceiver for communications on the 2400-2500 MHz band. The firmware of the two STM32 MCUs is developed with RIOT OS.
