kreis AeroDiDOS-System

AeroDiDOS is the first deep integration of Novetel’s SPAN System for aerial surveying applications, e.g. aerial imaging (with less or no ground-controls) or scanner-missions.

AeroDiDOS includes AeroTopoL Flight Management System, S/W which supports direct access to real-time SPAN-data. The GPS-INS solution is used for navigation and for pre-orientation of image-footprints in real-time.

Beschreibung

AeroTopoL’s Flight Management makes use of 10Hz-Refreshrate to enable extreme smooth and precise navigation.

AeroDiDOS Main Unit logs GPS and IMU RAW-data with up to 200Hz on SD-cards for post processing. This saves an additional PC for the on board data logging and enables an easy data transfer for the post flight workflow.

The AeroDiDOS Main Unit is releasing the camera and registering the mid exposure pulse. In parallel it logs the pulses on the SD-card and interfaces to the AeroTopoL S/W for release control. Scanners can automatically be started and controlled, too.

AeroDiDOS enables the same flexibility as the SPAN-System, meaning various IMUs can be combined with the Main Unit. Tightly coupling in real time and in post processing is supported.

For raw-data post processing, the market leading software package, the Inertial Explorer from Waypoint, is bundled with AeroDiDOS. Once processed, the data can be transferred to AeroTopoL S/W for further processing, enabling a smooth workflow for the whole data processing.
