Computer Controlled Navigation System (CCNS4) and AEROcontrol for Aerial Survey Flight Missions

The system can be used for flight guidance in remote sensing applications or as a very precise inertial reference system (after post processing) for any other application.

The Standard CCNS4 is a guidance, positioning, and sensor management system for aerial survey flight missions. It provides complete and comprehensive solutions for mission planning, aircraft guidance and camera (as well as other sensors) management during photo flights or scanner missions, additionally post-flight record keeping, data management and documentation. Since the complete mission can be prepared before flight, the pilots are guided
by the system from waypoint to waypoint.
The system consists of the airborne computer unit, 2 control & display units (5 ''), the AEROcontrol system, the DGPS Omnistar system and the CCNS World Wide Mission Planing software (WWMP).

Precision without ground station:

Position : 0.5-3 m (5m without OMNISTAR-DGPS)
Height : 1-5 m (15m without OMNISTAR-DGPS)
Attitude : 0.05 deg
Acq. Freq. : 50Hz

By using a ground reference station the accuracy can be significantly improved (up to 15 cm for position)
