The cubesat Lightsail-2 has been deployed and has communicated with ground stations. See The Planetary Society's LightSail 2 Healthy as Mission Team Continues Spacecraft Checkouts, where it says:
Telemetry from LightSail 2 shows the spacecraft's major systems are operating normally. The spacecraft's tumble rate is near zero, indicating it successfully used its electromagnetic torque rods to stabilize itself after ejection from Prox-1.
The mission team adjusted LightSail's internal clock and uplinked data to help the CubeSat determine where it is around the Earth, which is required for solar sailing. Mission ground stations at Cal Poly San Luis Obispo, Georgia Tech, and Purdue University have all received LightSail 2 data. Additionally, the SatNOGS worldwide ground station network has been tracking the spacecraft and capturing additional teleme
Question: What kind of transmitters and antennas do the Lightsail-2 ground stations at Cal Poly San Luis Obispo, Georgia Tech, and Purdue University use to communicate with the cubesat?
