spacelab-gs-controller v0.0.2

Ground Station Controller

Tracks the given satellite and controls orientation of the antenna and SDR tuning frequency accordingly.

Required parameters:

• TLE string
• ground station location latitude (deg), longitude (deg), altitude (km)
• motor controller (rotctld) address and port
• SDR (gqrx) address and port
• carrier frequency of the data signal
• refresh interval

Components

AntennaController

Uses jspredict to calculate azimuth and elevation, which are sent to motor control daemon (rotctld) over TCP connection.

GqrxController

Uses jspredict to calculate doppler correction, which is used to remote control SDR (gqrx) tuning frequency over TCP connection.

Networker

Simple module for required TCP communication.
