I thought it would be nice to have a GNSS satellite display program that showed the sky like you see it (sort of!) so I wrote
gnssview. (The images above are a bit old. The skies are a rather busier these days.)
Some of its features are:
- Communicates with the GNSS receiver via UDP multicast (this means you need to provide a program that multicasts satellite positions).
- Displays the tracks of satellites across the sky and satellite signal strengths.
- It animates the position of the sun based on your location. An analytic sky model is used to produce a realistic-looking sky, based on the current position of the sun. When the sun goes down, an image of the night sky is used.
- Looks best with a user-supplied 360 degree panoramic photo. I used hugin to make my panorama.
- It moves. The view is a continuous pan across the panorama. Makes it look a bit more dynamic since the satellites move quite slowly.
- There's a configuration file that allows you to play with many settings.
- It can power down the display at programmed times to save power and the monitor.
If you find a bug let me know.
Download gnssview source code here. There are some instructions and setup hints in the README. Sorry, no binaries.
