Fox telemetry
by Mike Seguin 06 Feb '16

06 Feb '16

I just hooked up my FT-847 9k6 output to the Fox Telemetry decoder vers 1.03 There was a decent pass over VT just now and I see 82 decodes. My question is: in the settings screen, I didn't have 'upload to server' checked so nothing uploaded. Is it possible to send that data after the pass? (I now have 'upload to server' checked) Mike -- 73, Mike, N1JEZ "A closed mouth gathers no feet"

Hi everybody, I'll be active in the rare grid GH52dx (farm QTH) on most satellites from today until next wednesday. Try to find me specially on AO-07 and FO-29. 73 Ron PP2RON P.S. Internet access there is very limited. --- Este email foi escaneado pelo Avast antivírus. https://www.avast.com/antivirus

FoxTelem Version 1.03 released
by Chris Thompson 06 Feb '16

06 Feb '16

This version of FoxTelem uses a new datafile format. While we store our data on the server in an SQL database, we use a flat file database for FoxTelem. A flat file format is nearly optimal for a program that mostly adds new data to the end of a growing list. With that said, we need to be able to load sections of the data into memory for efficient analysis. The new data file format allows that. If you have been downloading data from the server for analysis, you will see that this format is much faster. One major change is the ability to automatically switch between low speed and high speed. This will help unattended stations gather as much telemetry as possible. The "auto" mode actually runs both decoders at the same time, so make sure your computer has enough CPU power to cope. Graphing has been updated to support better analysis of the spacecraft by the AMSAT Operations team and amateur scientists everywhere. This version also contains new features that will be required for Fox-1Cliff and Fox-1D. You can download it here: http://amsat.us/FoxTelem/windows/foxtelem_1.03_windows.zip http://amsat.us/FoxTelem/mac/FoxTelem_1.03_mac.zip http://amsat.us/FoxTelem/linux/foxtelem_1.03_linux.tar.gz Version 1.03 Changes * Support larger volumes of data with much better speed in a segmented database * Auto detect high speed vs low speed telemetry * Allow the user to swap IQ channels in IQ mode * Allow graphs to be plotted as points (without lines) * Plot more labels on horizontal axis when many resets plotted and fixed some graph formatting issues * Graph formatting parameters are saved to config and reloaded when FoxTelem is restarted * When reset button pressed on graphs the average period is reset too * Swapped min/max values for solar panel temp on 1A * Fox-1A Solar panel voltage was (incorrectly) using the MPPT conversion * Fixed bug where HighSpeed Frames were unnecessarily held in the queue until the pass was finished * Cap max RSSI in the lookup table at -140dB to avoid spurious readings * Interpolate the middle of two samples for first difference calculation, for more accurate TCA calculation * Add SAFE mode bit to the Computer panel so that it can be graphed * Fixed bug where Radiation Graphs did not open at start up * Fixed bug where T0 file could be corrupted if URL returned bogus data * Fixed bug where FoxTelem gave many error messages but did not quit if the log dir was not writable * Skip NULL values for some measurements. Don't plot continuous labels to left of vertical axis. * MEMS diagnostic values are now in dps (vs Volts) * Fixed bug where radiation data could not be saved to CSV files * Fixed bug where FindSignal failed to lock if Track Doppler was not checked It also provides Support for Fox-1Cliff and Fox-1D: * Display HERCI High Speed frames on the Herci Tab * Display HERCI Housekeeping frames * Support the Fox-1D low res camera format * Implemented MPPT panel temperature conversion using Cubic fit * Sort camera images by reset and uptime not picture counter * Save position of the HERCI HS tab horizontal divider * Allow the user to specify the number of thumb nails to display on the camera tab * Display converted HERCI Housekeeping data -- Chris E.

AO-85
by Steve Kristoff 05 Feb '16

05 Feb '16

I decided to try receiving and decoding the AO-85 Data Under Voice telemetry, but it's not working. I suspect it's because my radio is filtering out the frequencies below 200 HZ. So, what are folks doing to get this telemetry? If you want to just point me to an old thread on the forum or a file on the AMSAT site, I'm OK with that. Steve Kristoff AI9IN skristof(a)etczone.com

Who's representing AMSAT at RARSfest in Raleigh, NC?
by John Brier 04 Feb '16

04 Feb '16

I noticed AMSAT is listed as one of the exhibitors at the Raleigh Amateur Radio Society's hamfest. I'm curious who will be representing and what the plans are, especially if any demos are planned, because I'll probably go. http://www.rars.org/rarsfest/ John, KG4AKV, in Raleigh

Suitable transceivers for Earth-Moon communication? And a question about allocations
by Tomas Härdin 04 Feb '16

04 Feb '16

Hi (attempt #3 at sending this mail. maybe this list doesn't allow attachments?) Tomas SA2TMS here. I am involved in a group that's trying to put together a scientific probe that will hitch a ride to the moon, courtesy of PTscientists (one of the Lunar XPrize teams) [1,2]. One of my major concerns is how get a reliable backup link going for running operations during the lunar night. The lander acts as downlink relay during the lunar day, but is not available during the night (and likely not after the night either). Hence the need for a secondary link. Throughput requirements are quite modest, as little as 10-100 bits/s may be acceptable. There is an average of around 800 mW of electrical power available. The geometry is somewhere between a 4U and 5U CubeSat. I have two questions for this list, assuming it's the right place to ask them: 1) What are some transceivers that may be suitable for this problem? I have found some candidates, but I'm interested in hearing more suggestions. The path loss is obviously quite significant (197 dB on 70cm). Choice of band(s) comes down to possible antenna geometries. 2m is a bit on the low side for a dipole to fit (it'd have to fold). 70cm is OK. At 23cm and above patch antennas start to become feasible (a huge plus). 2) Where do I go to apply for frequency allocations in the amateur satellite bands? Some sources say IARU, some say AMSAT. Others indicate I should talk to my national agencies (PTS, SSA). That's all for now. If you have any questions, ask :) /Tomas [1] http://scube.se [2] http://ptscientists.com/
