The RINEX converter will then correctly adjust the height down to ARP. Store the ANTEX file in any folder at a computer contributing to the Trimble 4D Control Server system. Different antennas may have antenna phase centers differing by several centimeters. Instead, the location of the phase center is a function of the direction from which it receives a signal. Along with L2C and L5 tracking, it provides better performance around obstructions compared to the R8 (model 1) but still struggles to maintain a fixed RTK solution around medium-height trees.

Enter this value in the Antenna height field and set the Measured to field to Bottom of antenna. The U.S. National Geodetic Survey NGS (Gerald L. Mader) gives the following information at its WWW home page www.ngs.noaa.gov/ANTCAL/images/summary.html: A GPS geodetic solution for a baseline provides the vector between the phase centers of the antennas at either end of the baseline. You can also use the offset values shown as a reference if your local regulations require you to manually calculate the APC height as a check for fieldbook purposes. The choice is yours. 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 Trimble R8s easily integrates with Trimble SSeries total stations and the innovative Trimble V10 imaging rover. 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.

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. Entering the antenna height and antenna measurement method enables the software to calculate the height of the Mechanical Antenna Phase Center above the ground station. 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: The RINEX converter assumes that the antenna height was measured in the defined way. endstream endobj 34 0 obj <>stream Using antenna files for antenna calibrations, www.ngs.noaa.gov/ANTCAL/images/summary.html. 0000032850 00000 n 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.
