[amsat-bb] Pollux and Castor weekend experiment
Hello all, There will be a laser ranging experiment this weekend from Maui. Both satellites have retroreflectors all over. Part of the experiment is to pulse a laser at the satellites at a high rate in an attempt to measure the spin rate. The results will be compared with the student MEMS payloads. There will also be an attempt to do a long wavelenth IR imaging to get thermal signatures. If you can collect data from now through Sunday and send the data to a...@juno.nrl.navy.mil, it will be greatly appreciated. Also, if you want, you can send your address and I will mail out a QSL card. I will be getting them printed real soon. Thanks to all who have sent me telemetry.

[amsat-bb] ANDE website telemetry corrected
Hello all, For anyone who is trying to analyze the sensor data, I discovered I put in the wrong information about the magnetometers. The values are not counts but measurements in uTesla. More info will be posted such as sensor locations and magnetometer orientation. I just need to get the CAD guy to crank out a few pictures. Ivan ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Pollux Castor Telemetery
Castor is running the same power. I think the issue is the instruments mounted to the shells are interfering with the transmission. I was given permission to write up a couple articles about the satellites. I'll start that and push them for release and to the AMSAT journals.

Most telemetery frames posted are from Pollux. Is Castor running less power? Thanks, Armando, N8IGJ ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Re: FX.25 on Castor and Pollux
AS usual we are catching up. We are planning to work on the FX25 software tonight on some new hardware so we can release schematics and code. Ivan Jim Heck wrote: Hi Folks, Does anyone know if these sats are sending FX.25 yet? I havnt found much on the web about FX.25, but it sounds exptremely cool. The https://goby.nrl.navy.mil/ANDE/Amateur_Radio.html web site refers to a FX.25 decoder. Is this yet available, I wonder? 73s Jim G3WGM ___ Sent via amsat...@amsat.org.

[amsat-bb] ANDE heard
Hello all, Thanks to Henk for capturing data from Pollux. He heard Castor/KD4HBO-1 but not decode. Current surface temperature is ranging from 6 to 9C. Interior temperature is ranging from -3 to -1C. It looks like all high school MEMS experiment payloads are functioning. Some of the data doesn't look right but that is part of the experiment. When I get a chance, I'll send out the MEMS telemetry format and info on the MEMS devices. This was collected from Henk, PA3GUO.

[amsat-bb] Re: ANDE-2 Deployment
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 Ivan Joe wrote: 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.? Joe WB9SBD Robert Bruninga wrote: 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. Bob, WB4APR ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: ANDE-2 Deployment
Sorry, deployment is Thursday. A standard AX.25 TNC will work. FX.25 wraps error correction data around the packet. I'll get info on the FX25 decoder up real soon. Ivan Nigel G8IFF/W8IFF wrote: OK, so presumably a standard AX25 TNC in kiss or RAW data mode and FX25 error correcting software to post process the data? Looks as though the deployment from the shuttle didn't go ahead. They've been doing engine burns during the past minutes. jmfranke wrote: No he means FX.25: From the Milcom/BTown blogs: The communications board contains the transmitter and receiver. The transmitter operates at 2 meters and can put out up to 1 watt of signal. Power level is adjustable. The transmitter can operate at 1200 baud AFSK and 9600 baud FSK. The transmitter uses the AX.25 protocol. An experimental FX.25 protocol will be tested that adds forward error correction capability to the AX.25 protocol and still allows typical TNCs to decode the packets.
