mmGPS+ Parameters

In mmGPS aided RTK survey, a wireless sensor connected to the Rover picks up the signals from the laser transmitter for accurate (millimeter) elevations.

Note: When measuring the height of the Rover antenna, include the following values:
- the height of the PZS-1 sensor unit;
- the partial height of the 5/8 inch plug.

To configure the mmGPS+:

  1. Select the Receiver port, which is connected to the mmGPS+ Sensor.
  2. Select the Sensor Gain to adjust the gain on the mmGPS+ Sensor. Select Auto to automatically control the mmGPS receiver’s detection level of the transmitter’s signal.
  3. Enter the Height Difference Limit value to set the threshold for the difference between GNSS and mmGPS+ height measurements. If the GNSS height and mmGPS+ height differ by more than the amount entered, the mmGPS+ icon will change to warn the user.
