How many digits in NMEA GGA position?

Hi,

I plan to switch to Emlid GNSS receivers but before I place the order, I was wondering, what is the number of digits for the latitude and longitude in the NMEA GGA Stream?

Usually, in RTK we configure our receivers to get at least 7 digits in order to get sub-centimeter resolution.

Thank you.

Hi @rreignier,

Welcome to the community forum!

NMEA stream from Reach receivers consists of several messages. GNGGA message has 7 decimal places in the latitude and longitude values.

Reach receivers don’t require this configuration to establish an RTK-link. To obtain a centimeter-level accuracy, you need to set up the corrections output/input in the ReachView app. This will automatically calculate the Fix solution if all the placement requirements are met. Please check the Base and Rover setup guide for more details.
