Trimble makes it fairly simple. Use the System Properties to access the Station Information. 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. 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. Antenna Type Select the type of antenna being used with the receiver. Therefore, the file must reside there. For the same type . V = sqrt( (0.168 * 0.168) - (0.091 * 0.091) ) = 0.141, V is now vertical to the center of the bumper.
