BEVO1 Deployment from STS-127
The University of Texas at Austin deployed BEVO1 in space on July 30, 2009 at 7:27 AM CDT via the STS-127 Space Shuttle Picosatellite Launcher (SSPL).
We appreciate anyone who can help us tracking BEVO1!
BEVO1 Downlink Information:
Beacon Mode Downlink Freq: 437.325 MHz Modulation: FM, 200mW, Morse Code, ~20 WPM
Data Mode Downlink Freq: 437.325 MHz Modulation: GMSK, 1W, 9600 baud, AX.25 (default) FM, 1W, Bell 202, AX.25 TLE's:
1 99999U 9211.52399245 .00015326 99081-9 77971-4 0 19 2 99999 51.6397 84.3142 0004954 91.3966 248.8994 15.80682654 2322
BEVO1 is a 12.5 cm cube and 3 kg in mass. The purpose of the mission is to collect data from NASA's DRAGON GPS receiver.
BEVO1 has two modes, data and beacon. The data mode is on over most parts of the United States, and the rest of the time, the satellite is in beacon mode. Also, anyone tracking BEVO1 can record what they hear at http://paradigm.ae.utexas.edu/opsThe University of Texas also has additional information at: http://www.utexas.edu/news/2009/06/09/picosatellite/
NASA describes DRAGONSat as an anticipated eight-year program with a launch of the satellites approximately every two years. The first three missions will test individual components and subsystems while the final mission will culminate with the successful docking of two satellites. Refer to http://tinyurl.com/m2blyc for additional mission information.
The University of Texas at Austin has developed BEVO1 and Texas A&M University has developed AggieSat-2 for this mission. Both satellites will perform the initial data acquition testing of the DRAGONSat program.
Space-Track doesn't appear to have seen BEVO. Was it physically seperate from Dragonsat or on the same spaceframe?

Hi Nigel,
Dragonsat was the designation for both Aggiesat2 and Bevo1. They were ejected together from the SSPL, but it appears that they failed to separate. Here is an official update:
----------------------- Still no signals from BEVO1, although beacon packets were heard from AggieSat2. The current theory on the state of the satellites is that only partial separation occurred. The inhibit switches keeping the satellites powered off have been closed, allowing the satellites to boot up. However, it is likely that the antennas did not deploy correctly, leaving the antennas disconnected from their respective transmitters. AggieSat2 transmits with 1W of power so it is easier to hear, while BEVO1 only transmits with 200mW during beacon mode. -----------------------
UT Austin has also posted some pictures here:

Thanks for all your help!

This is an interesting picture. Close examination of it seems to indicate that "some" of the separation system worked, but some of it hung up. Kind of like what happened to the Agena Target Adapter that was launched for I think Gemini 9.
