Gpredict 1.2 released

by

After one year of development, bug fixing and testing we have decided that it was time to make a new release of Gpredict. This release features several new features such as the rewritten layout engine as well as lots of bug fixes.

The new layout engine allows any combination of views to be created in a NxM grid, see an example screenshot:

The sky at a glance widget has been improved to look nicer and to be more interactive. Moving the mouse over a pass pops up an info widget showing infor about the pass. Clicking on the pass brungs up the pass details dialog.

The sky at a glance gives you a quick overview of upcoming passes.

The info pop-ups have also been added to the map view and the polar video. Moving the mouse over a satellite will show the current position of the sattelite as well as time until next AOS or LOS. You can see a demo video here:
