ThaiIOT Project

In the THAIIOT project, we built a 3U CubeSat with LoRa module and private LoRaWAN-server payload.
The main goal of this project was to develop the payload for CubeSat in the low-earth orbit to receive uplink data via LoRa technology between LoRa module and private LoRaWAN-server on Cube to store data and then use S-band transceiver to downlink the data to ground station.

In addition, we improved network security between ground LoRa nodes and the private LoRaWAN-server by using Advanced Encryption Standard (AES). This project was initiated and operated by Navaminda Kasatriyadhiraj Royal Air Force Academy (NKRAFA), Thailand, and was funded by National Broadcasting and Telecommunications Commission (NBTC) through Broadcasting and Telecommunications Research and Development Fund for Public Interest.

From the calculation results, the calculated link budget showed that the LoRa technology can transmit and receive data at a distance up to 2000 km. By assuming the transmitted data size of 35 bytes, the possible maximum data rate was 292 bps, which required 1.81 s of Time on Air (ToA).

Moreover, the experimental results verify the capability of the THAIIOT payload to successfully transmit the data up to 2,200 km
