Allow to start in a particular group

Could be done with php.

?group=GPS

You would want to modify the javascript rather than introduce a new php script. The satSet.onCruncherReady function's first few lines are to determine if you passed an international designator. You could add a second parameter check to look for "group" and then if a group exists to select it.
