All of the specs pages for the EM20g mention that it has built in GPS/GLONASS/etc. is there a way to access this data in GoldenOrb?

I would like to know this as well.
Also, how does the card get the GPS signal?
I believe there are only 4 antenna snaps on the card.
Where do you put the GPS antenna?

You can set the GPS receiver to activate automatically on modem start with the AT command:

AT+QGPSCFG="autogps",1

Restart it to activate obviously.

Then you can read your position at any time with:

AT+QGPSLOC=2

This gives your location in decimal degrees. Use zero or one instead of two in that command to get degrees and minutes.

Deactivate with: AT+QGPSCFG="autogps",0

From memory, the modem uses the diversity antenna for GPS as well as MIMO.

More on this:

What does the command AT+QCFG="gpsdrx" return on the EM20-G?

If supported, this command determines whether GPS shares the diversity antenna.

Unfortunately none of those commands seem to work. They all just return “ERROR”.
