Antenna Configuration

Use these settings to define the antenna being used by the receiver.

Select Receiver Configuration / Antenna.

Antenna Type – Select the type of antenna being used with the receiver.

RINEX Name – Allows the selection of the type of antenna being used with the receiver using the RINEX name of the antenna rather than the Trimble name for the antenna. Setting this field automatically sets the antenna type in the preceding field.

Antenna Serial Number – Enter the serial number of the antenna being used.

Radome Serial Number – Enter the serial number of the radome enclosure.

Antenna Measurement Method – Select how the antenna height is being measured. This setting is only applied at the base station in the generation of correction messages (CMR or RTCM). The height output from the receiver does not account for this offset; the Antenna Phase Center (APC) height is always given.

Antenna Height [m] – Enter the measured height of the antenna. This is typically measured from a ground marker or the mounting point of the antenna. This setting is only applied at the base station in the generation of correction messages (CMR or RTCM). The height output from the receiver does not account for this offset; the Antenna Phase Center (APC) height is always given.

Apply Antenna Correction to – When the RTCM V3 check box is selected, the Base antenna is set to a “Null Antenna” and no antenna model parameters are sent to the rover receiver. When using Trimble receivers exclusively, Trimble recommends that you select the check box. In some case, when using a third-party rover receiver, the check box should be left cleared and the antenna model parameters are sent to the rover. To determine the settings for this parameter, check with the third-party manufacturer.

If available, an image of the selected antenna is displayed so that you can confirm that you have selected the correct antenna.
