If you have Output displacement enabled, then the measurements are still from the RT1003
and not from the output displacement point.
GNSS control
Figure 40. NAVconfig GNSS control properties window
The GNSS control option (Figure 40) contains advanced options that control how the GNSS
information is managed in the RT1003. To adjust the feature, click in the Settings column,
then click the
button to open the properties window.
The GNSS algorithm tab can be used to select the algorithm used for blending the GNSS and
the inertial data in the Kalman filter. The Recovery tab can be used to decide how to begin
using GNSS measurements if they have been rejected or ignored for a period of time.
The Use GNSS receiver's calculations option turns off gx/ix™ mode and uses the receiver's
default algorithms for calculating a GNSS solution.
Use OxTS gx/ix raw data processing algorithm enables gx/ix mode. The gx/ix processing
uses the raw data from the GNSS and custom algorithms to compute position and velocity
tailored to the needs of the Kalman filter. It also improves performance in poor GNSS
environments using single satellite aiding technology and tightly coupled GNSS and inertial
measurements. In environments where signal lock may be difficult to maintain (e.g. urban
canyons), gx/ix mode is recommended to achieve the highest accuracy.
Currently, not all GNSS modes are compatible with gx/ix. Table 19 details the current
compatibilities of gx/ix mode.
