RN2903 LoRa
× LEO CubeSat
Deployment and field testing of Microchip RN2903 LoRa transceiver nodes communicating through low-earth orbit cubesats as airborne LoRaWAN gateways — extending sensor connectivity to remote agricultural land and public works infrastructure where terrestrial networks don't reach.
Connectivity where
no tower exists.
The RN2903 module operates at 915 MHz with a link budget exceeding 157 dB — sufficient to close a link to a LEO cubesat at ~550km altitude. Ground nodes wake on schedule, transmit a compact LoRaWAN frame during the satellite's ~8-minute overhead pass window, and return to deep sleep. No terrestrial infrastructure required.
- ✓ RN2903 transceiver — 915 MHz, +18.5 dBm max power
- ✓ LoRaWAN 1.0.4 OTAA — over-the-air activation
- ✓ LEO pass scheduling — pre-computed TLE-based windows
- ✓ Deep sleep between passes — <10µA standby current
- ✓ Solar + LiPo power profile for multi-year field deployment
- ✓ Encrypted payload: AES-128 AppSKey + NwkSKey
Agriculture.
Public Works.
Rural SA.
DALRRD (Department of Agriculture, Land Reform and Rural Development) needed soil, rainfall, and dam level monitoring across communal land and commercial farms in provinces where cellular coverage is patchy at best. The Department of Public Works requires infrastructure monitoring on roads, bridges, and government assets in similarly remote areas. The cubesat gateway layer closes both coverage gaps.
- ✓ DALRRD: soil moisture, rainfall, dam level, temperature
- ✓ Dept. Public Works: bridge strain, road surface, flood markers
- ✓ Data delivered to SA government data portals via REST
- ✓ 3 provinces active · Limpopo, Free State, Northern Cape
- ✓ Phase 3: expand to 300+ nodes across all 9 provinces
