Hello,

Why you should use a GPS dongle: GPS is a wonderful addition to mounts which do not have an integrated GPS solution. What does a GPS provide?

1. Location
2. Time zone
3. Elevation
4. Relative Time.

KSTARS has EKOS. Wiithin EKOS, INDI can be configured to be dependent on GPSD. I used the GPS to set the postion and time zone of the session. KSTARS needs both to setup the star catalogs and the position of Polaris and other important celestial objects. Having the location allows KSTARS to point to objects relative to the location. When GPSD is not working, Warsaw Poland is its default location.

So, Yes. A GPSD is necessary when not connected to NTP over the internet. GPSD is better when a RTC device is not installed. Even with an RTC, location is important.
