AEROcontrol is IGI&qout;s GPS/IMU system for the precise determination of position and attitude of an airborne sensor. This can be the position of the projection center and the angles omega, phi, kappa of the aerial camera system or an airborne laser scanner.

The AEROcontrol system consists of an Inertial Measurement Unit (IMU-IIe) based on fibre-optic gyros (FOG) and a Sensor Management Unit (SMU) with integrated high end GPS receiver. There are three different systems available with different accuracies.

AEROcontrol can be operated either as a stand-alone system or combined with other Sensor Management Units via its ethernet interface. Because of its modular design, the AEROcontrol SMU can be adapted to customer needs easily. The SMU can manage three different events (eg. trigger for camera or real-time data) and one IMU input.

AEROcontrol Benefits
The accuracy ot the AEROcontrol is sufficient for direct georeferencing for almost all aerial sensors. The obtained angular accuracy matches nicely with the “”single pixel FOV”” of modern digital aerial cameras and the geometrical resolution of airborne LiDAR systems.
In case the directly measured positions and orientations should be used to support an automatic aerial triangulation process, AEROoffice provides an easy interface for AT software packages. For large scale photogrammetric projects, where a higher accuracy is required, the use of AEROcontrol results as additional information for an aerial triangulation (Integrated Sensor Orientation) leads to large savings in GCP&qout;s and processing time. Together with digital imaging sensors, this ISO (Integrated Sensor Orienation) results in an optimal georeferencing result with a minimum of manual interaction.
