V-GST-0801: Perform a data transmission test between ground station and the satellite during the cold plateau thermal vacuum test by using the HackRF SDR. Required data will be sent to the ground station from the satellite through the HackRF SDR.
V-GST-0802:Perform a data transmission test between ground station and the satellite during the hot plateau thermal vacuum test by using the HackRF SDR. Required data will be sent to the ground station from the satellite through the HackRF SDR.
V-GST-0804: Perform a data transmission test between ground station and the satellite during the thermal cycle vacuum test by using the HackRF SDR. Required data will be sent to the ground station from the satellite through the HackRF SDR.
V-GST-0805: Perform a data transmission test between ground station and the satellite during the post TVAC ambient test by using the HackRF SDR. Required data will be sent to the ground station from the satellite through the HackRF SDR.
V-GST-0809: Test that the TLEs for a similar satellite using ISS orbit are being downloaded regularly and automatically by the actual ground station antenna tracking software application and can be sent to the ground station computer located at STARLab. The ground station computer in the StarLab will be remotely connected to the UMARS computer.
V-GST-0900: Use the ground station to get telemetry from a similar satellite. Download the telemetry and assess its data size and look at the downlink capability of the transceiver and the GS modem to verify that it is possible to receive 1 MB per day for the GS
V-GST-0902: Use the ground station to get telemetry from a similar satellite. The antenna should be able to acquire data at a min elevation angle of 20 deg
V-GST-0905: Use the GS to acquire an ISS orbit satellite's telemetry and verify that the GS is able to perform frequency shift key modulation and demodulation. The data should be properly acquired and convertible to readable format
V-GST-0910: Use a service monitor to monitor the output performance of the ground station with dummy CSP packitized data input to confirm that the minimum signal-to noise power density is 50 dBHz.
V-GST-0920: Use a service monitor with various dbm output to compare the performances between the Gomspace radio and ground station with the same test input to confirm that the max bit error rate is 10 ^ -5
V-GST-0930: Get actual telemetry from an ISS orbit satellite, process it and provide the data in readable form to pass the test. This will verify that the system is capable of providing processed telemetry.
V-GST-0942: Download telemetry from an ISS satellite and run the algorithm to check for errors in incoming transmissions. This test should prove that the transceiver software has the capability of error tracking
