Past Research

The past research activities include remote sensing imager development at the University of North Dakota.  The CSNAP director was involved in two National Aeronautics and Space Administration (NASA) projects; Agricultural Camera (AgCam) and Airborne Environmental Research Observational Camera (AEROCam).   The objectives of both these projects are to provide farmers and ranchers with reliable remote sensing data for precision land management.  As for the AgCam project, we have designed and built a two-band high resolution digital camera system for the International Space Station.  The flight AgCam unit is built and it will be launched with the Space Shuttle. 

 

 

The other remoter sensing project, AEROCam, involved the development of a four-band digital imager for an airplane.  Currently, this system is in operation.  In the AEROCam project, we were responsible for integrating Global Positioning System (GPS) and Inertial Navigation System (INS) to obtain accurate position and attitude information of the camera.

 

 

Other research activities were in two areas; stochastic optimal control and satellite

control.  In the area of stochastic optimal control, I focused on the theoretical

development of the minimal cost variance stochastic control technique for a linear system.  In this research, the full-state-feedback and approximate output-feedback solutions were derived using the dynamic programming approach.  This novel method was applied to a real-time seismic structural control application at the University of Notre Dame. 

In the area of satellite control, we designed and implemented an orbit maneuver software package for a commercial remote sensing satellite, Kompsat at Electronics and Telecommunications Research Institute.
