The height output from the receiver does not account for this offset; the Antenna Phase Center (APC) height is always given. To do so, the following is required: Note - Trimble strongly recommends that you do not edit the default files in the IGSConfig folder. With a fixed height range pole, the height is a constant value. The data collector will adjust for slope to each point. Nevertheless, Trimble recommends backing up your individually created files.

However, be beware of the fact that the receiver module which will use this ANTEX file needs it at its local computer. 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. The Trimble R8s easily integrates with Trimble SSeries total stations and the innovative Trimble V10 imaging rover. Almost all GPS antennas currently in use are azimuthally symmetric and the dominant phase variation occurs with elevation. If the Microcentered antenna (or a Compact L1/L2 antenna) has a groundplane measure to the underside of the notch in the groundplane.

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. 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 following describes how to measure the height of an Trimble R10 receiver using the lever on the R10 extension, when the R10 is mounted on a tripod. 0000058290 00000 n The user can't do anything about the satellite phase center; however it is modeled to a great extent within the higher accuracy orbital ephemerides. 0000059194 00000 n Therefore, the file must reside there. If you deviate from the selected measurement method, you will have to manually correct the antenna height. To obtain the antenna phase center (APC), you must add an additional vertical offset, using the formula: Weight: 820g. 0000078046 00000 n 0000018631 00000 n Antenna Measurement Method Select how the antenna height is being measured. 0000040265 00000 n 0000015923 00000 n These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Trimble 4D Control Server does not support relative calibrations.
