Take the ARISSat-1 Survey

09/27/2011

AMSAT is inviting radio amateurs to complete a 19-question survey regarding ARISSat-1. “Please take a few minutes to answer the questions,” said Steven Bible, N7HPR. “The survey results will be posted to the official ARISSat-1 website.” ARISSat-1 was deployed from the International Space Station in August 2011 and is active on the following frequencies and modes:

  • 145.950 MHz FM Downlink: FM transmissions will cycle between a voice ID as RS01S, select telemetry values, 24 international greeting messages in 15 languages, as well as SSTV images. If you successfully receive the SSTV transmissions, you are invited to upload your picture to the ARISS SSTV Gallery.
  • 435 MHz - 145 MHz Linear Transponder: The linear transponder will operate in Mode U/V (70 cm up, 2 meters down). It is a 16 kHz wide inverting passband from 435.742 to 435.758 MHz and the convention will be to transmit LSB on the 435 MHz uplink and receive USB on the 145 MHz downlink between 145.922 and 145.938 MHz.
  • 145.919 MHz/145.939 MHz CW Beacons: The CW transmissions will be call sign ID RS01S, select telemetry and call signs of people actively involved with the ARISS program.
  • 145.920 MHz SSB BPSK-1000 Telemetry: The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q. 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, the backup of BPSK-400 format is being transmitted.
