SPAN Installation

Chapter 2

The offset between the antenna phase center and the IMU axis must remain constant and be known accurately (m). The X (pitch), Y (roll) and Z (azimuth) directions are clearly marked on the SPAN-IGM enclosure. The SETIMUTOANTOFFSET parameters are (where the standard deviation fields are optional and the distances are measured from the SPAN-IGM to the antenna):

x_offset y_offset z_offset [x_stdev] [y_stdev] [z_stdev]

This example assumes a default mounting configuration and shows a -X offset, -Y offset and +Z offset.

A typical RTK GNSS solution is accurate to a few centimetres. For the integrated GNSS + INS system to have this level of accuracy, the offset must be measured to within a centimetre. Any offset error between the two systems shows up directly in the output position. For example, a 10 cm error in recording this offset will result in at least a 10 cm error in the output.
