Generic Aiding example results

Examples with and without OxTS Generic Aiding

In order to explore the difference Generic Aiding can make to a project, a low speed urban driving test was undertaken with GNSS data blocked.  This made Generic Aiding the only aiding source.  The results were then compared to a reference with RTK GNSS.

The following results were gained using a Velodyne VLP-32 based SLAM system. The local SLAM positions were transformed to global velocities in the INS frame to use as Generic Aiding updates.

The data plot above shows a typical driving scenario through an urban environment. The green trace is the reference using full RTK GNSS with the INS, while the orange trace is with GNSS completely blocked and using the generic aiding updates from the SLAM system. We can see even in the total absence of GNSS positioning, the addition of Generic Aiding data helps keep the navigation on track and stops large errors in the inertial dead reckoning building up. After almost 2 km of driving there is a slight offset between Generic Aiding and GNSS, the graph below shows this error as a function of distance travelled. The error settles at around 0.5% distance travelled.
