Parus-T1 Spacecraft

Dedicated to receive APRS signals on three major global frequencies.

Dedicated to receive APRS signals on three major global frequencies: 144.640 MHz, 144.390 MHz, and 144.800 MHz. Record the Received Signal Strength Indicator (RSSI) data for each received APRS packet.

Utilize a Global Navigation Satellite System (GNSS) receiver to determine the CubeSat's orbit location during signal reception. Store the received APRS data, RSSI values, and corresponding location data in the On- Board Computer (OBC) memory. Transmit the stored data to ground station. Students will also be extensively involved in mission data analysis and will gain hands on experience in understanding ionospheric propagation and its impact on terrestrial and satellite radio communications. The beacon packets shall not be encrypted and made public to the community via websites.

Community participation will be encouraged through online leaderboards for example SatNOGS network. PARUS-T1 has an APRS digipeater to provide global amateur activities at the same frequency of ISS APRS channel 145.825MHz. Data format of PARUS-T1 health telemetry and payload raw data will also be published and welcome all amateurs to receive 436.850MHz for packet data of AX.25 protocol on 1200bps. The APRS payload will receiving signal strength RSSI for major 3 global APRS frequency, and data downlink for VHF propagation analysis.
