1987 to 1989
Member Technical Staff, Advanced Systems Engineering
Litton Guidance & Control Systems, Woodland Hills, California
Transferred to Guidance & Control Systems Division to pursue my interest in fiber optic products. Engineering proposal manager for successful All Optical Towed Array (AOTA) proposal. Principal investigator for Fiber Optic Acoustic Detection System (FOADS) program. Developed real-time 10 Hz to 20 KHz FFT spectrum analyzer with one-third-octave outputs based on TMS 320C30 and 386 PC. Designed digital signal processing techniques for fiber optic hydrophone demodulation. Engineering proposal manager for various fiber optic gyro (FOG) proposals. Investigated signal processing techniques for FOGs.
Principal investigator for Integrated GPS/Inertial System R&D program. Engineering manager for GPS Guidance Package (GGP) study. Provided consulting expertise to all Guidance & Control Systems GPS/Inertial programs.
1985 to 1987
Director, Systems Engineering
Litton Aero Products
Promoted when new Engineering VP was appointed. Responsible for all systems engineering activities across all product lines (INS, IRS, AHRS, Omega, GPS, and advanced systems). Reorganized directorate into four departments (analysis, design, integration, and test) each managed by an Engineering Manager. Increased directorate from 35 engineers to 55 engineers to support workload. Reduced back to 35 engineers eighteen months later when company management decided to sharply curtail engineering activity. Established a summer intern program for engineering students.
Managed system design of fault-tolerant fiber optic gyro IRS system, development of improved strapdown system calibration, investigation of RLG instrument block vibration, development of PC based system test equipment, and conceptual design of new products. Implemented policies and procedures which improved systems engineering effectiveness and efficiency.
1981 to 1985
Litton Aero Products
Recruited by Litton to lead their GPS development effort. Starting form scratch with a team of 3 engineers developed working brassboard during the 1st year. Conducted successful flight tests by the end of 2nd year. Completed production prototypes within 3 and 1/2 years. Interfaced with Manufacturing for limited production run of 25 LTN-700 GPS Navigation Sets. Developed system architectures for 2nd and 3rd generation products (LTN-710 and µNAV). Developed codeless L2 signal-processing technique incorporated in Western Atlas Aero Service's GPS survey set (MINI-MAC). Developed single channel GPS signal generator for receiver testing. Developed a digital Omega receiver.
Managed a project budget of $1 to $2 million per year. Directly responsible for the GPS systems engineering and RF design groups (increased staff from 2 to 7 engineers). Managed CMOS gate array and custom GaAs ASIC developments. Established a state-of-the-art RF development lab for work from 10 MHz to 2 GHz.
1979 to 1981
Magnavox Advanced Products and Systems Company
Recruited by Magnavox to join their Phase II GPS development team. Designed the set moding for the five, two, and one channel GPS Phase II User Equipment (UE) sets. Performed various system engineering tasks for the GPS Phase II UE sets.
1979
Teledyne Systems Company
Returned to Teledyne after receiving my MSEE from USC. Designed a simplified test procedure for the DRIRU-II gyro that significantly reduced test time. Conducted a processor requirements study for Missile Accuracy Evaluator (MAE) GPS receiver.
1978 to 1979
Worked my way through the USC MSEE program by consulting for Teledyne. Conducted performance trade-off studies for GPS Phase IIA program. Performed hardware/software integration of Tactical GPS Guidance (TGPSG) receiver. Designed and implemented a GPS satellite simulator using off-the-shelf subsystems.
1977 to 1978
Joined Teledyne after completing my BS at Caltech. Designed and implemented an improved graphics capability for St. Mary’s Loran-C navigation system. Developed and analyzed algorithms for Tactical GPS Guidance (TGPSG) receiver.
