GEM45 mount comes with a GPS receiver which goes into a a port on the mount. When not using stellarmate, the mount gets time and location from this module. However, stellarmate Kstars has no option to get this data from the mount. Is it possible to do so?
Make sure you get a GPS fix for the mount. Then start KStars, open the preferences, go to the INDI tab and select "Mount Updates KStars". Then open Ekos and start INDI. You should see that KStars gets updated with the time and location of the mount, which it got through the GPS.
