“…It connects to the computer and handy talky using RS-232 connector. The radio transmission used by APRS utilizes the AX.25 protocol which is a standard protocol used in radio amateurs [16], nano/pico satellite communication [17], [18] and remote monitoring [6], [19] [20].Radio packet transmitted on the Link Layer is sent in small blocks of data called frames. Several types of frames exist in the AX.25 protocol.…”

To communicate with the ground station, nano satellite requires a communication system that serves in real time to regulate the procedure with ground station. One of the missions of nano satellites is the retrieval of telemetry data from sensors that transmitted using APRS technology (Automatic Packet Reporting System). We designed a prototype to monitor sensor by utilizing the APRS. Real-time sensor data was transmitted to monitor through radio using AX.25 protocol. On the transmitter side, an APRS Tracker integrated with a microprocessor ATMEGA 1284P to modulate the AFSK signal. The existence of this AFSK signal is used to transmit and receive telemetry data using handy talky. We use a computer with AGWPE software to demodulate the AFSK signal and UI-View32 to show the telemetry data. The results showed that the telemetry data can be displayed on the receiver side and acquired in real time. The accuracy of temperature sensor received by the receiver is 92.97%, and humidity sensor is 90.57%. There was a delay of 1 second for the reception of telemetry data directly.

Master courses need to have a practical element, applying already known concepts to concrete problems. In this paper, the design and manufacturing of a radio link using APRS protocol over AX.25 will be presented as coursework during several lab sessions. The aim is to create a system that is able to poll data from several sensors and send them wirelessly with a software implemented signal generator in a microprocessor.
