Provide an individual ANTEX file for each individual antenna. When I look at the base station information (for the CORS) the broadcast antenna type comes up as ADV NULL antenna with an antenna offset value (the value almost matches the L1 offset of the CORS antenna) . The GNSS receiver reduces all of the measurements at the L1 and L2 Antenna Phase Centers to the Mechanical Antenna Phase Center. Antenna Height [m] - Enter the measured height of the antenna. Setting the correct antenna type slightly improves the accuracy of the GNSS receiver, since the L1 and L2 Antenna Phase Center offsets are known and accounted for. The actual Antenna Phase Centers for L1 and L2 frequencies are points (or clouds) in space, typically above the Mechanical Antenna Phase Center. 0000000016 00000 n To evaluate the effect of antenna phase center offset and its variation on the baseline solution, three eld experiments have . Slower re-initialization times when signals are lost due to obstructions. 0000032850 00000 n To change the GNSS antenna height during an integrated survey you must change the current target height. Trimble R10 Trimble Zephyr 3 | Antennas | Trimble Geospatial The offset between the antenna phase center and the reference point (usually bottom of antenna) for Trimble receivers is stored in a configuration file and used by field apps to more correctly calculate elevations. In addition, the antenna model accounts for elevation-dependent biases of the antenna, so that the satellite tracking is corrected at various elevation angles.

The actual Antenna Phase Centers for L1 and L2 frequencies are points (or clouds) in space, typically above the Mechanical Antenna Phase Center. Antenna phase center offsets - Trimble Inc. However, the local environment around the antenna can introduce both azimuth and elevation variations from the ideally measured phase patterns Two types of antenna calibrations exist, the relative antenna calibrations which are determined by field measurements relatively with respect to a reference antenna and absolute calibrations. 74 0 obj <>stream Almost all GPS antennas currently in use are azimuthally symmetric and the dominant phase variation occurs with elevation. %%EOF Please do not submit your actual street address, just a city, town or regional location. 0000032405 00000 n It offers sub-centimeter phase center accuracy and superior signal tracking of current and near-future GNSS signals. Weight: 820g. When the Antenna Type field is set, the value of the RINEX Name field is automatically set, and vice-versa. 3. Refer to the following diagram where (1) is the Trimble R10 receiver, (2) is the bottom of the antenna mount, (3) is the bottom of the quick release, (4) is the corrected height to the APC from the bottom of the pole.
