Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna (25 w EIRP). Transponder is only active during night passes and at weekends Passband may be up to 15 kHz higher depending on on-board temperaturesĮducational Telemetry beacon is 300 mW during day and 30 mW at night. Inverting SSB/CW transponder 300 mW PEP.145.935 MHz BPSK Telemetry 30 or 300 mW.Donations to the ARISS program for next generation hardware developments, operations, education, and administration are welcome - please go to to contribute to these efforts.ĪRISS–Celebrating 20 years of continuous amateur radio operations on the ISS! The ARISS-Pi promises operations autonomy and enhanced SSTV operations.ĪRISS is run almost entirely by volunteers, and with the help of generous contributions from ARISS sponsors and individuals. Follow-on next generation radio system elements include an L-band repeater uplink capability, currently in development, and a flight Raspberry-Pi, dubbed “ARISS-Pi,” that is just beginning the design phase. For the IORS, parts are being procured and a total of ten systems are being fabricated to support flight, additional flight spares, ground testing and astronaut training. It also provides on-orbit redundancy to ensure continuous operations in the event of an IORS component failure. voice repeater and APRS packet), providing diverse opportunities for radio amateurs. This second system enables dual, simultaneous operations, (e.g. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system.Ī second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. It will enable new, exciting capabilities for ham radio operators, students, and the general public. The design, development, fabrication, testing, and launch of the first IORS was an incredible five-year engineering achievement accomplished by the ARISS hardware volunteer team. It consists of a special, space-modified JVC Kenwood D710GA transceiver, an ARISS developed multi-voltage power supply and interconnecting cables. The IORS was launched from Kennedy Space Center on Maon board the SpaceX CRS-20 resupply mission. Special operations will continue to be announced. System activation was first observed at 01:02 UTC on September 2. Initial operation of the new radio system is in FM cross band repeater mode using an uplink frequency of 145.990 MHz with an access tone of 67 Hz and a downlink frequency of 437.800 MHz. The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on July 26, 2000. This first element, dubbed the InterOperable Radio System (IORS), was installed in the International Space Station Columbus module. The ARISS team is pleased to announce that set up and installation of the first element of our next generation radio system was completed and amateur radio operations with it are now underway. The Amateur Radio on the International Space Station (ARISS) announcement reads: International Space Station – Image Credit NASAĪt 01:02 GMT on September 2 a cross band FM amateur radio repeater with a downlink on 437.800 MHz was activated on the International Space Statio. ![]()
