AMSAT Online Satellite Pass Predictions. N2YO provides real time tracking and pass predictions with orbital paths and footprints overlaid on Google Maps. [6] It features an alerting system that automatically notifies users via SMS and/or email before International Space Station crosses the local sky.
Heavens-Above is a non-profit website developed and maintained by Chris Peat as Heavens-Above GmbH.The web site is dedicated to helping people observe and track satellites orbiting the Earth without the need for optical equipment such as binoculars or telescopes.
Amateur-satellite service (also: amateur-satellite radiocommunication service) is – according to Article 1.57 of the International Telecommunication Union's (ITU) Radio Regulations (RR) [12] – defined as «A radiocommunication service using space stations on earth satellites for the same purposes as those of the amateur service.»
Visible pass of the International Space Station and Space Shuttle Atlantis over Tampa, Florida, on mission STS-132, May 18, 2010 (five-minute exposure). An orbital pass (or simply pass) is the period in which a spacecraft is above the local horizon, and thus available for line-of-sight communication with a given ground station, receiver, or relay satellite, or for visual sighting.
Fox-1B, AO-91 or AMSAT OSCAR 91 [3] is a United States amateur radio satellite. It is a 1U Cubesat , was built by the AMSAT-NA and carries a single-channel transponder for FM radio . The satellite has a whip antenna for the 70 cm and 23 cm bands (uplink), and a second antenna for the 2 m band (downlink).
This corresponds to an inter-satellite spacing of approximately 73 km. The major consideration for spacing of geostationary satellites is the beamwidth at-orbit of uplink transmitters, which is primarily a factor of the size and stability of the uplink dish, as well as what frequencies the satellite's transponders receive; satellites with ...
AMSAT-OSCAR-40, also known as AO-40 or simply OSCAR 40, [1] was the on-orbit designation of an amateur radio satellite of the OSCAR series. Prior to launch, the spacecraft was known as Phase 3D or "P3D". AO-40 was built by AMSAT. AO-40's project manager was Peter Guelzow of AMSAT-DL, the German AMSAT organization. Mr Guelzow holds amateur call ...
The IORS consists of a special, modified JVCKenwood D710GA transceiver, an AMSAT-developed multi voltage power supply and interconnecting cables. The IORS has a higher power radio, an enhanced voice repeater, updated digital packet radio (APRS) capabilities and slow scan television (SSTV) capabilities for both the US and Russian segments.
