Amateur satellite ready to go in to action

ARISSat-1, the satellite designed and built by amateur radio operators to specifically interest students in scientific and technological careers, is scheduled to be deployed from the International Space Station (ISS) this Wednesday August 3.

The extra-vehicular activity (EVA)  is due to be broadcast on NASA TV , starting at 1430  UTC (Coordinated Universal Time )  when the hatch of the ISS will open.

ARISSat-1 will then leave the space station and be secured to an airlock ladder and its solar panel covers will be removed. At 1507 it will to deploy site, activate its PWR, TIMER1 and TIMER2 switches, verify LEDs on, and deploy.

If all goes well with tomorrow's deployment, it will perform the following primary functions:

  • Two-way communication via UHF uplink and VHF downlink, for use by ham radio operators
  • Visuals of space from four cameras
  • Recharging of the satellite's battery using solar panels, enabling operation for months
  • Transmission of audio greetings in many languages, for reception via simple radios or scanners
  • Telemetry transmissions with updates on the health of the satellite
  • House an experiment from Russia's Kursk University that measures atmospheric pressure

ARISSat-1 design-team leader Steve Bible launched the limited-series Chips in Space Blog on EE Times' Web site last week, to both educate and entertain readers by relating the story of how he and his colleagues came to build the satellite, and the challenges they ran into along the way. Bible will also provide analysis of the satellite's deployment and functionality.

Bible will provide an update on the mission later this week on the Chips in Space Blog.

The satellite is a cooperative effort between AMSAT, ARISS (AmateurRadio on the International Space Station,) RSC-Energia (The RussianSpace Agency) and NASA. The design, development and construction of thesatellite was done by AMSAT volunteers. Through the use of ham radio equipment, students and teachers should beable to access and utilize the satellite from a classroom environmentwith minimal set up.
