Welcome on board

The International Space Station, presently nearly complete, is permanently manned by teams of astronauts and cosmonauts. Most have an amateur radio licence.

Amateur Radio societies from the ISS partner countries, in USA, Canada, Russia, Europe and Japan, have set up ARISS - Amateur Radio on International Space Station.

ARISS is a volunteering working group devoted to develop and put into operation the onboard amateur radio station. ARISS-Europe is the European branch of ARISS.

145.200 MHz * IARU Region 1 (Europe, Russia and Africa)

* In Region 2 (Americas) and in Region 3 (Asia, Australia, Pacific) the Voice Uplink frequency is 144.490 MHz

** The amateur radio station located in the Columbus module is currently operational with the UHF Ericsson transceiver and packet system using the frequency of 437.550 MHz.
To utilize the the packet system, operators need to set the UNPROTO path to ARISS (the id is RS0ISS) for digi relay or they may connect to the BBS using the callsign RS0ISS-1.  
The packet beacon is set for 2 minute intervals so it may not appear to be active over many parts of the world but keep listening and mind the Doppler shift (+ or – 10 KHz).

Phase 2 Hardware comprises two multiband transceivers supporting 2 meter (144-146 MHz) and 70 cm (435-438 MHz) transmit/receive and L-band uplink operation. HF operation will also be provided. Power output is 10-25 Watts.

Together with an RF tuning unit, power supplies and a computer, the transceivers are mounted on a Velcro-backed table.

This equipment is located in the Service Module, the crew's living quarters.



phase2 module

Four antennas were deployed by EVA (space walk) and clamped on handrails outboard the Service Module. One of the antennas is 2.5 meters long and supports HF operation.

A documented description of the Phase 2 Hardware is available as a downloadable pdf file.


The original amateur radio equipment on board the International Space Station is located in the Functional Cargo Block (FGB), named Zarya. phase1 equipment

Phase 1 is a handheld 5 watt VHF FM transceiver connected to an outboard antenna system that supported docking of the FGB with the Russian Service Module, named Zvesda. These antennas, designed for use near the 2-meter band, no longer support docking and can be used by the ARISS team permanently.

A similar UHF handheld transceiver is on board but will be deployed later.

For voice operation the astronauts use headphones with a microphone attached. Packet Radio is provided by means of a Modem and a portable computer. An Adapter interconnects these units.
