In the first experiment three GPS antennas have been used; two Leica GS15, and one Trimble R8-Model 3. Influence of GPS antenna phase center variation on precise positioning In this paper, five different type antennas are applied.

R8 TDS TSC realtime antenna phase center offsets It offers sub-centimeter phase center accuracy and superior signal tracking of current and near-future GNSS signals. If you want to understand the location of the L1 and L2 Antenna Phase Centers with respect to the Mechanical Antenna Phase Center, add the Antenna Model page and then select the antenna type. Make sure that the antenna calibration provides absolute antenna phase center corrections. We use TSC2 running both Survey Pro 4.11.2 and Survey Controller 12.46. 0000039565 00000 n To evaluate the effect of antenna phase center offset and its variation on the baseline solution, three field experiments have been performed. These average phase center locations are a weighted average of all the individual phase centers for each of the measurements included in the solution.

For the Bottom of notch measurement method when the antenna is on a tripod, refer to the following diagram where: (5) is the uncorrected height from the ground mark to the underside of the notch. Trimble makes no warranties and assumes no obligations or liabilities hereunder. Refer to the following diagram where (1) is the Trimble R10 receiver, (2) is the lever of the R10 extension, (3) is the corrected height to the APC from the ground mark and (4) is the uncorrected height. %%EOF Configure and Scale With Ease The actual Antenna Phase Centers for L1 and L2 frequencies are points (or clouds) in space, typically above the Mechanical Antenna Phase Center. Use these settings to define the antenna being used by the receiver. . Trimble Antenna.ini Antenna Viewer Trimble and one of . If this receiver is mounted on a tripod, measure the height to the bottom of the groove between the gray base and the white top of the antenna, and select Center of bumper in the Measured to field. Different antennas may have antenna phase centers differing by several centimeters. In this case, if you did measure vertically to the center of bumper, the manual correction to APC would be S + additional vertical offset: In this case, to obtain the correct antenna height in the RINEX file, you should manually correct the antenna height to APC, enter that height in the antenna height entry of the RINEX converter and then select APC as the measurement method. This topic describes how to measure the height of an antenna mounted on a range pole when the Measured to field is set to Bottom of antenna or Bottom of antenna mount. Change the horizontal and vertical tolerance to be 0.001 to get more points. For antenna types listed in the antennas.xml database file, Trimble 4D Control Server lets you provide individual calibrations so that information from special calibrations can be used for processing. www.trimble.com/trimbleconfiguration_ts.asp. The AV39 is a lightweight, FAA TSO certified antenna for primary flight navigation with an ARINC 743 footprint. However, typically only the coordinates of the ground station which the antenna is setup over are known. This folder contains a file called antennas.xml, which defines the antennas supported by Trimble software; and it contains at least two ANTEX (.atx) files, which provide absolute, elevation and azimuth dependent antenna corrections. Trimble has developed leading high-precision solutions to ensure you operate successfully in all conditions. Then record the average as the uncorrected antenna height. 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. These can be found under the "Access Calibrations for All Antennas" menu above.
