Abstract
To improve the tracking abilities of the Primrose Lake Evaluation Range, the Sensor Systems Group of DREV Electro-optics Division is developing a microprocessor-based control system for cinetheodolites. The new system will take azimuth and elevation data coming from several cinetheodolites to estimate, in real time, the trajectory of the object being tracked. This estimate will then be used to generate pointing information for each cinetheodolite. The present report describes the analysis made to choose an estimation method. Four different methods are presented and evaluated for computation speed and accuracy: two least squares methods, an adaptive extended Kalman filter and an alpha-beta filter. The alpha-beta filter was found the most suitable for the application.
