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.

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 - OperationalThe 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 - OperationalThe 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.
AMSAT needs your telemetry from ARISSat-1/KEDR both during the test and after deployment from the International Space Station. Since there are no "Whole Orbit Data" storage mechanisms onboard ARISSat-1/KEDR, your submissions are the only way for AMSAT to collect the spacecraft telemetry and KURSK experiment results.
- Recorded ARISSat-1/KEDR and Kursk telemetry CSV files (in the ARISSatTLM folder) can be sent as an e-mail attachment to arissattlm.org
- If you are running ARISSatTLM and receiving the signal "live" from ARISSat-1/KEDR, please enable the telemetry forwarding option.
- The latest telemetry can be seen LIVE on your computer or cell phone.
When you receive the downlink signal from ARISSat-1/KEDR you are invited to send your report to the following e-mail boxes. You will receive a PDF certificate by e-mail.
Students and school groups are especially welcome. We look forward to your report!
Your report must contain the following information:
- The signal you received:
- the secret word*,
- an SSTV image, or,
- telemetry data
- Your name or group name
- The date/time of reception
- City, State and Country
- Your e-mail address of where to send your certificate. You will receive a PDF certificate via email.
- Secret word* contest to: secretword@arissat1.org
- SSTV image to: sstvreport@arissat1.org
- Telemetry data to: tlmreport@arissat1.org (either digital or voice report of the data you received)
* Those who do hear the secret word or call sign please do not put it out to the world. That would ruin the contest for those still waiting for their station to be in range.
