Ardusat-1 and Ardusat-X Deployed from ISS!
Very early yesterday morning, Ardusat-1 and Ardusat-X were deployed from the International Space Station. Shortly thereafter, they began transmitting their beacons! If you're a ham radio operator and you'd like to help track the beacons, we've added the details to the bottom this update. The Ardusat team is also hard at work running through an exhaustive number of system checks. Meanwhile, we have a number of great pictures to show you (courtesy of NASA/JAXA)! You'll notice that there are 3 satellites in the photos. The third is Pico Dragon - a cubesat from Vietnam!
The initial TLE for AS-1 and AS-X will be the same as the ISS until they put some distance between each other and are assigned their own Noad IDs. TLE for ISS: http://www.celestrak.com/NORAD/elements/stations.txt (What is a TLE?)
Both satellites will have a Morse beacon (FM-modulated 800Hz tones) that is transmitted at 20 WPM every two or three minutes on 437.000 MHz. The beacon will be structured in the following format:
ArduSat-1 beacon: Battery voltage (uint16_t), RX_counter (number of received valid data packets, uint32_t), TX_counter (number of sent valid data packets, uint32_t), “WG9XFC-1″
ArduSat-X beacon: Battery voltage (uint16_t), RX_counter (number of received valid data packets, uint32_t), TX_counter (number of sent valid data packets, uint32_t), “WG9XFC-X” Submitting a beacon packet:
You can submit a beacon as plain text to email@example.com – be sure to put the word “packet” in the subject line so that we can parse it quickly. Submitting audio:
You can submit audio as an email attachment. Send an email to firstname.lastname@example.org – with the audio file as an attachment.
* IARU recently reported the frequency of Ardusat as 437.325 MHz. The correct frequency is 437.000 MHz
