Three-dimensional flight-path reconstruction by means of spline approximation

In NLR TR 82075 U, a method has been developed to reconstruct the flight-path of a symmetric flight, by representing this path by a set of splines. In the present report, the same method is being applied to a three-dimensional flight over a rotating earth. Preliminary results are comparable in accuracy and computing time to the Kalman (Square...

Improvement of the superposition of geographical data in KOSMOSS

Since mid 1982, the Royal Netherlands Meteorological Institute KNMI has to its possession a ground station (KOSMOSS), which receives and processes high resolution imagery, acquired from Tiros-N type weather satellites. To determine the weather positions in the images, the ground station is equipped with the capability to superpose, in real time,...
