The sketches for Fossast-1b and 2 appear to have been deprecated in favor of a Qt based control panel. This panel contains a interpreter that processes serial messages sent to and from the ground station. https://github.com/FOSSASystems/FOSSA-GroundStationControlPanel
For those who desire to use the simpler terminal based approach, this repo contains an updated sketch for Fossasat-2. Included are the ability to use newer public commands to interface with the satellite. Commands not enabled are password protected for use by the FS-2 team only. See https://github.com/FOSSASystems/FOSSASAT-2/blob/master/docs/Communication%20Protocol.md for the command list.
First generation 2P Satellite dedicated to demonstrating new miniaturized technology for picosatellites developed by FOSSA. To be launched in Q1 2020 aboard a Firefly Alpha launch vehicle.
The main payload of FossaSat-2 is an OV2640 low-resolution CMOS camera. GSD is >50m/pixel. A Skytraq GNSS reciever is being used to test active TLE generation for PocketQubes. GPS Payload Supported by the Galileo Science office.
Active pointing is carried out by using integrated solar panel magnetorquers, 2 16-bit sun sensors and an IMU sensor.
An SX1268T Chip is used to establish a Morse, 9k6 GFSK and LoRa Downlink and a LoRa and 9k6 GFSK uplink.
