This command reports the current GPS Lat/Lon, local coordinates and GPS solution status. The latitude and longitude are reported in the DD.MMSSSSSS format. In this example, the latitude is 42 degrees, 21minutes, 46.4414 seconds north. The longitude is 71 degrees, 8 minutes and 31.5699 seconds west. Negative longitudes indicate longitudes west.
The next three items are state plane or local coordinates depending on the transformation in the Align Local Coordinates command. The HRMS and VRMS are measures of the reliability of the position that the receiver has calculated. They correspond to the position horizontally and vertically, respectively. If the receiver is autonomous, not receiving corrections from a base, the RMS can be up to a few hundred feet. If this rover is computing a "Fixed" position, the RMS values should be less than one foot, probably close to a tenth of a foot. If the receiver loses the fix and becomes "Float", the RMS values will jump to between one and ten feet.
Depending on the type of GPS receiver, the Monitor screen will also show more values like radio link status and receiver battery status.
The Skyplot button will jump you to that window so you
can see the satellites the receiver is using.
