Zavitok Satellite Ground Station (M / S-L)
Sputnix
Satellite reception and control ground station for mission control centers and education. Receives telemetry from small spacecraft in LEO and uplinks commands. The "Zavitok-M" (SXL-GND-02-M) works in VHF/UHF; the "Zavitok-S/L" (SXL-GND-02-SL) adds an S- and L-band parabolic antenna for payload-data reception.
