Design and Implementation of SatGate / iGate YF1ZQA for APRS on the LAPAN-A2 Satellite

LAPAN-A2 Satellite, also known as LAPAN ORARI, is the second satellite developed by the Indonesian National Institute of Aeronautics and Space (LAPAN), especially by Satellite Technology Center. This satellite was launched in 2015, where one of the missions is to support disaster mitigation through the Automatic Packet Reporting System (APRS). The APRS is a method of transmitting messages, status, and positions – using specially formatted AX.25 packets messages. The critical part of the APRS infrastructure is Digital Repeater (digipeater) and Internet Gateways (iGates). The digipeater is usually used to retransmit data packets for extending coverage. The APRS digipeater of LAPAN-A2 is on 145.825 MHz. The iGate is a type of gateway APRS station that functions to collect packages from the radio and feeds them into a worldwide data streams on the internet. This paper describes the design and implementation of SatGate /iGate YF1ZQA for APRS on the LAPAN-A2 Satellite.
