Every ground station has a common purpose to serve, that is, the ability to send or recieve signals, process them and analyse them.
Transmission and reception of signals can only be done by antennas, thus antennas are an ubiquitous part of a ground station. In our ACE-GS we have two pair of Yagi-Uda antennas. One pair works in the VHF band (145MHz) and the other pair in the UHF band (437MHz). These antennas were designed, fabricated and characterised by our team with great efforts.
The antennas are big and cannot be hand held, so we have to mount it on a rotor which sits on a tower. The rotor provides torque to the mounted antennas while tracking satellites.
To power the entire ground-station and to equip it with Radio Frequency analysis facilities, the team will be using AD-8302 , CC-1020 along with an array of Low Noise Amplifiers (LNA) to detect even the slightest signature of the signal coming from the satellite.

The signal coming from the satellite will be received by the set of crossed Yagi antennae and sent to the electronic circuits via the Co-Axial cable . Once the signal reaches the electronic circuits these circuits would perform the function of converting the Radio Frequency signals into electrical signals to retrieve the modulated data from these signals. We also have an SWR meter to check the front-to-back power ratio of our antennas. This helps us to make sure that our antennas are efficient in radiating energy.
