Hi,
Thanks to Garie for the LUSAT data which decodes to 20.1Volts from the solar panels on the +Z (top) face of the satellite.
Mike Ruprecht DK3WN has a neat telemetry utility on his web site. Type in the letter groups and read off the corresponding values. Thanks Mike, I use this a lot. www.mike-rupprecht.de ( hope its still on the site I downloaded it in 2006)
The Grey Line idea I had in mind was to take a series of values for +Z as the satellite passed from darkness, across the grey line then into sunlight. Compare these with the position of the greyline shown on a tracking program.
I see two obvious flaws in the idea. The telemetry from Lusat is not continious so there are short gaps in the data. The unknown time delay between the spacecraft software capturing the voltage value and transmitting it.
AO-51 has much more sophisticated telemetry data so perhaps this is a good experiment to try on AO-51, when the soundcard software is released. As far I can tell the currently available telemetry software only works with the output from a hardware modem (expensive).
BTW - you can see the grey line in space. Watch a visual of the ISS going West to East in the evening. The ISS is very bright near TCA and as it gets into the East the brightness diminishes, goes through a dull orange colour, then dissapears into the darkness.
