Zavitok-M is a new modernized ground complex

SPUTNIX has released a modernized version of the data receiving and satelite controlling station. The Zavitok-M complex provides the possibility of two-way communication with small spacecraft and contains two helical antennas (instead of one, like the Zavitok station) with a higher gain on the rotary support device. The complex also includes panoramic antennas with a wide radiation pattern.

Zavitok-M is based on SDR-technology (software-defined radio technology). The complex provides calculation of the position of spacecraft in the sky, turning the antenna into a calculated point, calculating the necessary frequency shift to compensate for the Doppler effect, as well as automatic tuning of the frequency when receiving and transmitting in view of this shift.
