Systems Engineer

Mathematics, algorithms, instruction, & reports for the Global Positioning System (GPS)

dealing with navigation, satellite orbits, & spread spectrum communications

●Invented an algorithm to align the pseudo random noise chipping sequence to their

data bit - on par with the Viterbi one, but 10 times simpler computationally

●Calculated the GPS orbits in Earth-Centered, Earth-Fixed coordinates from ephemeris

parameters

●Developed a Kalman Filter - improved the PVT (position, velocity, clock bias) 10-fold

●Designed Runge-Kutta & Runge-Kutta-Fehlberg orbit propagators - numerical methods

to solve the differential equation describing the orbits

●Solved the GPS equations via Bancroft’s way & derived the Doppler velocity solution

●Designed Viterbi decoders to ascertain the efficacy of inter-satellite communications

●Solved anomalies presented by the California Division & introduced Bancroft's solution
