## Description

Designs, develops, implements, verifies and tests algorithms and software and simulation tools to perform guidance, navigation and control of aircraft, spacecraft, submersibles, surface ships, missiles, launch vehicles and upper stages during powered and coast phases of launch, flight, earth orbit, interplanetary cruise and orbital insertion, as well as during staging events. Navigation functions include the statistical processing of measured data points and their substitution into algorithms simulating physical reality. Guidance functions include the formulation of specific equations to achieve a desired position, orientation or orbit in space. Control design and analyses processes consist of the development of the control laws and hardware and software requirements for aircraft, launch vehicles and/or spacecraft.
