Note - Trimble 4D Control Server assumes and requires antenna calibrations used in the system to be absolute, because IGS products, such as their Ultra Rapid Orbits, are based on absolute calibrations. To evaluate the effect of antenna phase center offset and its variation on the baseline solution, three field experiments have been performed. :#5nsOQ`1aB i%*Qt?Sfv"zX| Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The difference in phase center positions from the GNSS satellite broadcasting antenna to the GNSS receiver phase center is where the phase measurement is determined. Part Number. 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. The height output from the receiver does not account for this offset; the Antenna Phase Center (APC) height is always given.

A compact, single-frequency antenna designed for aerial, land and marine applications. To obtain the antenna phase center (APC), you must add an additional vertical offset, using the formula: APC = 0.141 + 0.010 = 0.151 To correct to the antenna reference point (ARP) which is what RINEX expects, you then have to subtract the "bottom of antenna mount" correction from the APC: ARP = 0151 - 0.065 = 0.086 www.trimble.com/trimbleconfiguration_ts.asp. The following describes how to measure the height of a receiver using the lever on the receiver extension, when the receiver is mounted on a tripod. The actual Antenna Phase Centers for L1 and L2 frequencies are points (or clouds) in space, typically above the Mechanical Antenna Phase Center. In some instances, the terminology Nominal Antenna Phase Center may also be used, particularly when this point is at an arbitrary location or a location meant to coincide with similar antennas. In order to achieve results with millimeter accuracy these values must be considered carefully. In this paper, five different type antennas are applied. In the Configuration Toolbox software, you can add the Antenna page and then select the antenna type: If you select Bottom of antenna mount in the Method field, the True vertical height field shows the distance between the Antenna Reference Point and the Mechanical Antenna Phase Center. 20182023, Trimble Inc.

Trimble antennas have an antenna gain of 50 dB and a maximum suggested cable loss of 12 dB for a total of 38 dB system gain, so the Gain Amplification should be set to Disabled. The software automatically adds the appropriate offset value for the Measurement method you select when you enter the Antenna height value.
