- Turnstile antenna
- USRP with TVRX
- WXAPT example from GNU Radio
This experiment is trivial, nonetheless it validates the RF-part of the setup. It will also reveal whether additional hardware like LNA is required.
Currently, following NOAA satellites are active on 137 MHz APT and 1.7 GHz HRPT:
|SAT||APT Freq||HRPT Freq||Notes|
|NOAA-15||137.5000 MHz||1702.5 MHz||VTX-1 / STX-2 / MSB / OMNI=RCP|
|NOAA-16||OFF||1702.5 MHz||— / STX-2 / MSB / LCP|
|NOAA-17||137.6200 MHz||1698.0 MHz||VTX-2 / STX-1 / LSB / RCP|
|NOAA-18||137.1000 MHz||1707.0 MHz||VTX-1 / STX-3 / HSB / RCP|
|NOAA-19||137.9125 MHz||1698.0 MHz||VTX-2 / STX-1 / LSB / RCP|
Considering a time window of 24h starting at 10:00 UTC on Sat 13 June, there are many potentially useful passes.
We only need a few good passes for successful experiment and they should be distributed over time in order to allow debugging and problem fixing between the passes.
- Created this page preparing for the experiment to be carried out during the weekend 13-14 Jun 2009.
- Need to upgrade laptops and install recent GNU Radio
