The satellite is made mostly of parts from Digikey. The following processors are flying:
Pollux: 1 - Atmega168, 3 - Atmega168 Castor: 1 - LPC2106, 2 - Atmega168, IGLOO FPGA AGL125, Atmega128 Printed circuit boards from www.pcbexpress.com
When I get a chance, I'll see how much info I can release about the design and components. They are all commercial parts. Sensors are gyroscopes from Melexis and Analog Devices. Magnetometer is the PNI Micro mag 3-axis unit.
I'm preparing for PDR in a few weeks on another satellite program. Once I get past it, I'll put out more info on the sensors and telemetry.
I also want to write an article on the electronics.
Oh, and the radio transmitter in the satellites are based on this module. http://www.pratthobbies.com/proddetail.asp?prod=CANSAT-TX

Hi Bob,
have any idea as to what the telemetry may consist of?
And I'm assuming this will be a similar project? measure atmospheric drag?
Too bad they either wouldn't allow it, or for whatever reason the two birds didn't have a ground user capability.
This would be a perfect test for something off the shelf so to speak, no rad hardened stuff. just off the shelf couple hundred bucks of something, wouldn't that have been interesting.?

The two ANDE satellites (Castor and Pollux) will be deployed
from the Space Shuttle now that it has separated from the ISS.
Both satellites will be transmitting on 145.825 MHz. Castor will transmit telemetry every 30 seconds. Pollux every 33 seconds. Both are transmitting 1200 baud AX.25 packet Telemetry.
Most of the info is on the website: https://goby.nrl.navy.mil/ANDE.
Other than that, I don't have much detail information since this was built by a different team than our original ANDE project. The amateur payloads were developed by the Amateur Radio Club at the Naval Research Labs and got a ride on the ANDE spheres like we did a few years ago.
