A correctly configured GNSSreceiver is a pre-requisite for performing the GNSS
body vector measurements.
Note – Ensure that the configuration file is on the control box's system memory,
using USBSync if necessary. The *.cfg file path on the USB flash drive is

Note – You cannot send the configuration file to the GNSS receiver when the GNSS
