AEROcontrol is IGI’s GNSS/IMU system
for the precise determination of position
and attitude of an airborne sensor.
inthewebThe AEROcontrol system consists of an Inertial Measurement Unit (IMU-IIe) based on Fibre-Optic Gyros(FOG) and a Sensor Management Unit (SMU) withintegrated high end GNSS receiver. There are threedifferent systems available with different accuracies.
Together with AEROoffice the system provides theoptimal workflow for Direct Georeferencing (DG) andIntegrated Sensor Orientation (ISO).
It is the state-of-the-art position and attitude determination system for aerial & thermal photography, synthetic aperture radar, hyperspectral sensors and LiDAR sensor systems.

AEROcontrol benefits

AEROcontrol Sensor Management Unit

The system is designed for direct georeferencing of
airborne sensor data. The obtained angular accuracy matches nicely with the “single pixel FOV” of modern
digital aerial cameras and the geometrical resolution of airborne LiDAR systems.
For large scale photogrammetric projects, where a higher accuracy is required, the use of AEROcontrol
post-processing results as additional information for an aerial triangulation (Integrated Sensor Orientation)leads to large savings in GCP’s and processing time. Therefore AEROoffice provides an easy interface forphotogrammetric software packages. Together with digital imaging sensors, ISO is an optimal solution with aminimum of manual interaction.

AEROoffice software package:
The AEROoffice software package for post-processing the AEROcontrol data provides:

AEROcontrol SMU with IMU-IIe

achieve optimal results even under challenging
conditions• Transformation to more than 600 local coordinate systems• Coordinate System Editor for customized coordinate systems• Export to standard formats, Bing Maps™ &GoogleEarth™ (*.kml) format and defined customized formats• Simplified user interface to obtain optimal results for all users without extensive training andexperience

Combined with IGI’s mission planning and aircraft guidance & sensor management systems, AEROcontrol is
the perfect match for a turn-key solution for photogrammetry and LiDAR applications.

Depending on GPS constellation and distance from GPS Base/Monitor Station, a positioning accuracy better
than 0.05m RMS and an attitude accuracy of 0.007° RMS for heading and 0.003° RMS for roll and pitch isachievable in post-processing.
