- Fixed a bug that could cause the transponder frequency to "drift" away from the set frequencies.
- Added new transponder files received from David VK5DG.
- Minor enhancements in the user manual.... read more

Gpredict 1.0 beta 3 released


Gpredict 1.0 beta 3 has been released. This release includes an
implementation of Doppler tuning for full-duplex radios and a fix for
a bug that caused long latencies when opening or reconfiguring
modules. The user manual has been updated to be consistent with the
new Doppler tuning scheme.

Note that if you are already using gpredict with a full duplex capable
radio (e.g. IC-910, FT-847, TS-2000) you will have to review the
configuration to ensure that the MAIN/SUB or A/B settings are correct,
i.e. which one to use for uplink and which one to use for downlink.... read more

Gpredict: 1.0 beta 2 released

Gpredict is a real-time satellite tracking and orbit prediction application. Gpredict can track an unlimited number of satellites and display the data in tables and various graphical view.

Gpredict 1.0 beta 2 is now available for download. This release fixes several bugs identified in the beta 1 release and adds improved radio control algorithm, which now also supports uplink tuning with transceivers in simplex mode or duplex mode when using two different radios. Note that the radio control algorithm is likely to change again for the next release when introducing support for full duplex transceivers.... read more
