Features
SkyRoof combines satellite trackikng and SDR functions in one application, which opens some interesting possibilities.
For example, all satellite traces on the waterfall are labeled with satellite names, the boundaries of the transponder
segments follow the Doppler shift, and all frequency tuning is done visually, with a mouse.
The main features of SkyRoof are:
- detailed information about all satellites that transmit in the Ham bands;
- satellite tracking in real time;
- pass prediction for the selected satellites;
- visual representation of the current satllite position and future passes, using:
- Sky View - the view of the sky from your location;
- Earth View - the view of the Earth from the satellite;
- Time Line - the satellite passes on the time scale;
- Pass List - the details of the predicted passes;
- SDR-based waterfall display that covers the whole satellite segments on the VHF and UHF bands, with zoom and pan;
- SDR-based SSB/CW/FM receiver with RIT and Doppler tracking;
- audio and I/Q output to external programs via VAC;
- frequency scale with satellite names and transponder segments, Doppler-corrected;
- CAT control of an external transceiver;
- antenna rotator control.
The program can work without an SDR, or even without any radio at all, but many useful functions are not available in this mode.
