Antenna Configuration / Position Antenna / Vector Antenna

Applicable receivers:  All receivers

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

Select Receiver Configuration / Antenna.

The BD982 receiver uses two antennas. All data relating to position references the Position (POS) antenna. The Vector (VECT) antenna is used to provide vector information only, such as the heading and attitude.

For dual-antenna systems such as the BD982, this is the Position antenna. You can also use these settings to define the Vector antenna deployed with the BD982 receiver.

 

Antenna Type – Select the type of antenna being used with the receiver. Setting this field will automatically set the RINEX Name in the following field.

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.

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.
