Computing Applications Software Technology (CAST)
Computing Applications Software Technology (CAST) was founded in 1981 and was located in Los Alamitos, California. From the company’s inception, CAST has employed engineers with experience in both inertial technology and GPS receiver design. The primary focus of the company at that time was to perform system analysis, software design, coding and testing to facilitate the integration of GPS and avionics sensors for both loosely and tightly coupled navigation systems.
As a natural outgrowth of this development activity we developed a product called NAVSIM. NAVSIM was a Monte Carlo simulation software tool that was used to perform system analysis as well as aid in the development and tuning of Kalman filters.
