Views Read Edit View history. There has been significant amateur radio activity involving manned spacecraft as well. It was slightly damaged by a series of glancing collisions with the launch vehicle after separation, but has provided good service since, even after the on-board computer failed in due to prolonged exposure to radiation. Scheduled contacts are made with schools for educational purposes. AO's Mode B transponder is still in operation. The three common ways of identifying a satellite are by its:
Etymology of ham radio. In most countries, an amateur radio license grants permission to the license holder to own, modify, and operate equipment that is not certified by a governmental regulatory agency.

The first amateur satellites contained telemetry beacons. Solar cells were bought in batches of 10 or 20 from Radio Shack and tested for efficiency by group members. The information presented regarding functional satellites is outdated quickly as the Amateur Radio Satellite community has become very active in building and being provided educational secondary cargo launch opportunities. Radio spectrum , Electromagnetic spectrum. The satellite had to be built in a very specific shape and weight, so it could be used in place of one of the weights necessary for balancing the payload in the rocket stage.
Throughout the years, amateur-satellites have helped make breakthroughs in the science of satellite communications. Space Shuttle and the Russian Mir Space Station often communicate using the amateur radio equipment during the approach phase of a docking. This section's factual accuracy may be compromised due to out-of-date information. Amateur radio satellites Amateur radio Satellites by type. Positive when moving towards, negative when moving away. After the satellite passes overhead and begins to move away, this process reverses itself. Such satellites act as FM amateur radio repeaters that can be communicated through using omni-directional antennas and commonly available amateur radio equipment.
