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 Individually created .atx files will be kept in any case. 0000106006 00000 n During installation, updates, or automatic downloads, Trimble 4D Control Server checks whether the default files to be downloaded already exist and how old they are.

We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Alignment reliability and pole tip position reliability, especially during movement of the antenna while the pole tip is stationary, relies completely on the antenna height being correct. Want to participate in our Community Map? The height output from the receiver does not account for this offset; the Antenna Phase Center (APC) height is always given. Trimbles GNSS Division provides high-precision GNSS modules for positioning and navigation solutions that serve a broad range of applications in agriculture, construction, mining, aviation, marine, and industrial automation. The Trimble Zephyr 3 antennas offer full support for current and near-future GNSS signals including GPS, GLONASS, Galileo, BeiDou, OmniSTAR, Trimble RTX, and SABS. From mark to "center of bumper" is a slant height. When processing data from different receiver or antenna types together, the antenna phase center offsets are very important. All other trademarks are the property of their respective owners. Designed for applications in high shock and vibration environments like machine-control up to 75g shock and 20.4g RMS, the Zephyr Rugged is available in two versions with 5/8 mast mounting and with 3 mast clamp. Click the L1 Model Calibration or L2 Model Calibration button to view the offsets and the elevation-dependent tracking biases: These antenna calibrations are automatically used by the receiver when the correct antenna type is selected. However, a real antenna does not have a single well-defined phase center. 0 IGS_antennas.atx provides the approved antenna corrections supplied by IGS. 0000058290 00000 n These cookies will be stored in your browser only with your consent. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. 0000057821 00000 n 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. This setting is only applied at the base station in the generation of correction messages (CMR or RTCM). These average phase center locations are a weighted average of all the individual phase centers for each of the measurements included in the solution. If this antenna is mounted on a tripod, measure the height to the bottom of the notch on the side of the antenna. Trimble 5800 / R8 Receiver: Antenna Height Calculation in a RINEX File, This document is for informational purposes only and is not a legally binding agreement or offer. Trimble and one of the Leica antennas have been fixed over a leveled flat table as shown in Fig. By clicking Accept, you consent to the use of ALL the cookies. Then record the average as the uncorrected antenna height. The software automatically adds the appropriate offset value for the Measurement method you select when you enter the Antenna height value. 0000059591 00000 n R8 GNSS/SPS88x. 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. 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. 0000033281 00000 n The Trimble R8s easily integrates with Trimble SSeries total stations and the innovative Trimble V10 imaging rover.

Posted : December 25, 2016 2:01 pm Loyal (@loyal) Posts: 3787 Member Member If you deviate from the selected measurement method, you will have to manually correct the antenna height. The GNSS receiver has an interface to setup the antenna type, antenna height, and antenna measurement method. Our GNSS Antenna table allows you compare Trimble models to find the best fit for your application. With a fixed height range pole, the height is a constant value. Click Antenna Query to interrogate a supported antenna for its model and serial number. This chart shows the Trimble antennas that are available for the R750 receivers. These cookies will be stored in your browser only with your consent. Antenna Type Select the type of antenna being used with the receiver. All you have to do is provide your location below and submit. 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. 0000040907 00000 n 0000001738 00000 n www.trimble.com/trimbleconfiguration_ts.asp. The Trimble AG25 antennas are designed to support centimeter-level land platforms like agriculture and logistic vehicles. . This is typically measured from a ground marker or the mounting point of the antenna. Use the System Properties to access the Station Information. 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. If you are using a fixed height tripod, you can measure the height to the bottom of the antenna housing and select Bottom of antenna mount in the Measured to field. Provide an individual ANTEX file for each individual antenna. 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. If this variation is ignored, the measured baseline will be between the average phase centers of the two antennas. 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. On the other hand, organizations such as NGS (U.S. National Geodetic Survey) or IFE (Institute for Geodesy) may have calibrated additional antenna types. The default antenna information is stored in the Trimble Common Files\IGSConfig folder (the default path is: C:\Program Files\Common Files\Trimble\IGSConfig). The RINEX converter will then correctly adjust the height down to ARP. Refer to the following diagram where (1) is the Trimble GNSS receiver, (2) is the corrected height to APC and (3) is the uncorrected height of 1.80m. Site Map. Use these settings to define the antenna being used by the receiver.
