Experience

(Self employed) 1980-2004 as (Analytic Specialties Corp., and now Carefree Software, Inc.)

RAIM algoritm development for a GPS/WAAS receiver. Design, code, test per DO-178B.

Employed as a consultant to numerous companies and the U.S. Government in areas directly involved with all aspects of GPS. Responsible for many embedded software applications (design, code, test). Navigation and RAIM software design for a WAAS/GPS application.

Algorithm development and performance simulation for attitude determination using GPS.

Simulation and performance predictions for relative navigation accuracy for a space application of GPS.

Software upgrades for FAA certified application of GPS.

Assist with design refinement, responsible for code design, implementation, and test of a motor vehicle application of integrated GPS and vehicle sensors.

Implementation of wide-area differential GPS correction algorithms in a micro-controller.

Develop fast-running software using assembly for an application using a DS80C320 microcontroller.

Generation of embedded, communications software per Security Industry Association Standard (coded in C for a 68HC11).

Generation of FLASH memory reprogramming software (coded in C for a PC and MC68331).

Generation of a Software Requirements Specification for a spaceborne, GPS receiver. Duties also required design of Kalman filter, adaptive logic, upgrades to simulation test tools, and top-level design for tracking loop software.

Design, implementation and test of differential correction software for a vehicle-tracking application.

Provided support to NRaD, Warminster, PA with problem identification, software error analysis and fixes, and upgrades to the STel GPS Simulator software. As an aside project, rehosting the PC-based control unit software to run under Unix in X-Windows environment on a Sun SPARCstation.

Experienced with the classified aspects of the GPS signal, e.g., performed design, implementation and test of SA/A-S software for two different operating environments. Performed software design, implementation, and test of software for a GPS receiver PPS-SM, and an "inverse" version for use in a GPS signal simulator.

Systems engineer for the design of GPS signal simulator used for GPS receiver development. Simulator included models of user and satellite dynamics, and contained 1553B and NTDS interfaces.

As part of a proposal team, performed software requirements definition, design, implementation and test for the GPS Block IIR Satellite Payload Crosslink Transponder and Data Unit (CTDU). The CTDU was a frequency-hop communication device. Designed and implemented encryption/decryption software.

Lead analysis for the first, in-orbit GPS receiver application. Responsible for the identification of software-caused performance anomalies and the fix thereof. Also responsible for the software maintenance of the GPS signal simulator software.

Analyst and software engineer on a Navy program (PINS) which integrated many types of navigation sensors. Responsible for local area navigation Kalman filter. Authored many design folders, designed processing algorithms, coded, and tested. Generated test plans, specifications, procedures, and reports.

Designed and implemented modifications to Phase I User Equipments (receiver and simulator) to accommodate the change from developmental to the operational navigation message structure.

AVAND Systems Engineering (A.J. Van Dierendonck), 1979-1980

Consultant to Magnavox. Responsible for performance improvements to increase the dynamic capacity of the single-channel GPS Y-set. Work included problem identification, isolation, solution design and testing of both navigation and receiver processing software.

Intermetrics, Inc. Cambridge, MA/Huntington Beach, CA, 1975-1979

Actively involved in the design of navigation and filter algorithms for real-time implementation in the Magnavox X and Y user sets (integrated GPS/inertial/air data unit). Conceptual design, analysis of design concepts using simulation, code design and implementation, laboratory and field testing. Two years spent on-site at Magnavox doing additional design, software maintenance, integration testing, analysis of laboratory and flight test data, problem identification, software modification, and documentation. Analysis of Phase II user equipment requirements as part of an IV&V team.

Northrop Corporation, Norwood, MA, 1974-1975

Design and analysis by simulation of software for use in a strapdown navigation system. Designed test methods and data reduction techniques to calibrate IMU gyro and accelerometer parameters. Performed sensor and performance requirements analysis for a satellite navigation and attitude reference system. Analysis of alignment performance of a single-gimbal IMU. Designed and constructed simulation programs to evaluate new, IMU configurations and applications.

The Analytic Sciences Corporation, Reading, MA, 1969-1974

Study of temporal variations of the earth's magnetic field and their impact on navigation by magnetic map matching. Modeled submarine dynamics to access their impact on the accuracy of gravimeter surveys. Accuracy prediction study of various ICBMs with varying quality IMUs and initial conditions. Performance boundaries study for a self-contained, passive IMU that navigated for extended periods between reinitialization. Performance predictions for various SINS configurations and component accuracies. Recovery of geodetic data from SINS outputs - both theoretical and actual data. Analysis of doppler radar data to determine proper error model. Created many computer programs for direct and covariance simulations.

M.I.T. Instrumentation Laboratory, Cambridge, MA, 1968

Analytical studies related to autopilot design, reaction jet selection logic, and jet failure detection for spacecraft.

M.I.T. Lincoln Laboratory, Lexington, MA, 1967

Analytic study to determine effects of ionospheric refraction on L-band radar measurements of range and elevation.
