Version 8 Release Notes

Version 8.0 was released in December, 2009. New modules were added: Imaging, Power (now deprecated) and CubeSat.

New Features

Some of the features new in v8 are:

(Click here for a complete list of newly added functions)

Imaging

There is great interest in using cameras onboard satellites for navigation. The new imaging module allows you to apply a variety of imaging processing techniques to this problem such as corner and edge detection.

Corner detection using CornerDetector.m. The image is for a lens calibration pattern. The corner detector uses derivative information to find areas containing corners.

Edge enhancement using GaussianDerivative.m. This is a step in pattern recognition.

Optical Navigation

Planetary chord sizes for the Messenger mission. This plot is from an analysis of an optical navigation system that uses measurements of angle between planet centers and stars. The entire navigation system is part of v8.0.
