Detailed Description
ARISSat-1 is a microsat developed as a follow-on to the SuitSat-1 project. The satellite was launched to the ISS on January 28th, 2011, with deployment during an EVA (spacewalk) in summer 2011.

The ARISSat-1 satellite, presently still inside the ISS, will be turned on and use an external antenna to celebrate the 50th anniversary of Yuri Gagarin's first manned space flight. The transmissions will begin on Monday 11 April 2011 at 14:30 UTC and continue until 10:30 UTC on 13 April 2011.

Due to the fact that the solar panels are covered, the satellite will be powered only by the onboard battery. The satellite will run in low power mode. This means that the transmissions will cycle ON/OFF. They will be ON for 40-60 seconds and OFF for 2 minutes.

The satellite will downlink live SSTV images from four onboard cameras, live telemetry and messages on the CW, FM voice, and BPSK downlinks, as well as provide a 16kHz wide transponder for two-way contacts. All the uplinks and downlinks are based on software defined radio systems.

Telemetry will include spacecraft subsystem information, as well as data from the Kursk State University experiment. This experiment will sample the change in vacuum as the satellite slowly re-enters the atmosphere. Telemetry software is now available at http://www.arissattlm.org/download/ARISSatTLM_050_Setup.exe , with a user guide at http://www.amsat.org/amsat-new/i ... ickStart%281%29.pdf

ARISSat-1/KEDR is Deployed

The ARISSat-1/KEDR space craft was deployed from the ISS at 1843Z on August 3 after a hold based upon questions about the 70cm antenna. Congratulations to the ARISSat-1/KEDR team! Now bring on those reception reports. The satellite will be in High power mode (continuous transmission) when in the sun and go to Low power (40 seconds transmit/2 minutes idle) mode when in eclipse.


145.950 MHz FM Downlink - Operational
FM transmissions will cycle between a voice ID as RS01S, select telemetry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control.

If you successfully receive the SSTV transmissions, you are invited to upload your picture to
to the ARISS SSTV Gallery.

435 MHz - 145 MHz Linear Transponder - Operational
The linear transponder will operate in Mode U/V (70 cm Up, 2m Down). It is an 16 KHz wide inverting passband and the convention will be to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink. This mode is designed to work with low power transmitters and omni antenna. The linear transponder has been proven to be operational after deployment.

145.919 MHz CW Beacon - Operational
The CW transmissions will be callsign ID RS01S, select telemetry, and callsigns of people actively involved with the ARISS program.

145.920 MHz SSB BPSK-1000 Telemetry - Operational
The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions. The BPSK data will transmit satellite telemetry. When the CW2 beacon on 145.919 MHz is active this indicates that the BPSK-1000 format is being transmitted. If the CW1 beacon on 145.939 MHz is active this indicates the backup of BPSK-400 format is being transmitted.
