Building Automatic Antenna Tracking system for Low Earth Orbit(LEO) satellite communications

摘要

This paper purposed to implement the Automatic Antenna Tracking system in order to establish the communication with OSCAR (Orbiting Satellite Carry Amateur Radio) for voice (FM, SSB) and data communications (AX.25, packet radio, APRS). There are more than 5 fully operational Amateur satellites both U/V mode and CUBESAT in orbit act as repeaters or Store/ Forward. The often of the activities that came from International Space Station (ISS) sent out picture to ground station with SLOW SCAN TV(SSTV) data protocol. This research areas covered include Azimuth/Elevation Rotor Design and Schematic Controller Interface design.
