Inertial Navigation Systems - AEROcontrol

Overview

The AEROcontrol system consists of a fibre-optic gyro based Inertial Measurement Unit (IMU-IId) and a computer with an integrated 12-channel L1/L2 GPS receiver.

AEROcontrol can be operated either as a stand alone system or via IGI's CCNS guidance and management system for aerial survey flight missions. The CCNS and AEROcontrol together form a fully integrated system.

Sensor Integration

Installation material for the IMU, including a mechanical adapter plate, are available for the Wild/Leica RC10, RC20 / RC30, the Zeiss Jena LMK, LMK-1000, LMK-2000, and the Zeiss Oberkochen RMK-TOP aerial camera systems. AEROcontrol is successfully operated with different digital cameras and laser scanner systems.

Accuracy

Depending on GPS constellation and distance from GPS Base/Monitor Station, a positioning accuracy better than 0.1m RMS and attitude accuracy of 0.01 deg RMS for heading and of 0.004 deg RMS for roll and pitch is is available in post-processing. This accuracy is sufficient for direct georeferencing for many tasks. 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 GCPs and processing time.
