New Record for Minimum Drift in Navigation without GNSS of the UAV Navigation System

London. The safe, robust, and efficient execution of non-GNSS flight is a clear need in the market. UAV Navigation is committed to the simultaneous integration and fusion of several systems or onboard observers to face the most challenging scenarios.

In this case, the team has tested the “INS” (inertial) capacity of the VECTOR-600 system by simulating a failure in the system, forcing it to operate only with the inertial sensors and the magnetometer to determine its position and execute the guidance. In this scenario, the system begins to estimate its position by propagating its state through the iterative integration of its inertial sensors and airspeed data. This inevitably produces, due to this integration, an accumulation of error that results in a “position drift in time”.

These difficult conditions with a poor estimate of wind or a high level of vibrations have a very negative impact on the system, where the quality of the guidance, navigation, and control systems can be truly shown.

The ADAHRS-INS unit, based on MEMS technology, designed by UAV Navigation, which has also derived in the AHRS POLAR family and is included in its entire range of VECTOR autopilots, is capable of operating in this difficult scenario with position drifts of 16 meters/minute.

Delegating navigation to systems based almost exclusively on the GNSS signal entails risks that must be minimized in order to guarantee operational safety. That is why a system capable of operating with efficiency and precision, even in the absence of a GNSS signal, takes on special relevance for the professional operation of UAVs. UAV Navigation continues to create the most technologically advanced and reliable products on the market so that UAS platforms using its system are at the forefront of the industry and aligned
with regulations.
