Campus Universitario de Vigo
The HumSAT project is an international educational initiative for building a constellation of nano-satellites providing worldwide communication capabilities to areas without infrastructure. The HumSAT project will deploy a worldwide constellation of CubeSats with the associated ground segment and a user segment to provide telecommunications services in support to humanitarian and emergency applications, and to monitor parameters related to climate change. The system will provide data-relay services for sensors distributed around the world.

The HumSAT project will deploy a worldwide constellation of CubeSats with the associated ground segment and a user segment to provide telecommunications services in support to humanitarian and emergency applications, and to monitor parameters related to climate change. The system will provide data-relay services for sensors distributed around the world.
Two types of sensors will exist in the system:
- One-way sensors will transfer information to a remote user
- Bi-directional sensors will allow the transmission and reception of information off-line to/from a remote user
Telemetry
The satellite is transmitting 2 types of beacons, transmitting alternately. One modulated in CW Morse, that can easily be decoded (including the ID of the satellite, the battery voltage (looks now that the battery is full) and the PA temperature of the TTC), and the second is a telemetry frame modulated in GMSK 1.2K. including additional housekeeping telemetry.
