Posted : December 25, 2016 2:01 pm Loyal (@loyal) Posts: 3787 Member Member 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. You also have the option to opt-out of these cookies. When measuring or staking out points using IMU tilt compensation, make very sure the entered antenna height and measurement method is correct. 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 The RINEX converter will then correctly adjust the height down to ARP. In this paper, five different type antennas are applied. Antenna Type Select the type of antenna being used with the receiver.
