Experience

DRS Technologies
21 Continental Blvd.
Merrimack, NH
Postion: Senior Principal Software Engineer

At DRS I most recently worked on two radio direction-finding systems. One was a high-performance wide-band CIDF system that incorporated 8 custom FPGA's, three dual-channel wide-band receivers, and a Linux-based single-board computer in a VME rack. I developed the software that ran on the SBC. This software received high-level requests from network clients and sent the appropriate low-level commands to the FPGA's. It then received the results from the FPGA's and formatted them for the clients. Due to the asynchronous nature of the system and the high throughputs involved, this software involved resolving extensive queuing and memory management issues.

The other DF system was a man-portable battery-operated system intended for use by individual soldiers. This Butler Matrix system computed the phase difference between pairs of antennas using an analog phase-shift matrix and a CORDIC implemented in a Xilinx FX-60 FPGA that also contained the PowerPC processor. My responsibility was to incorporate the Butler Matrix algorithms into an existing code base and to develop algorithms for compensating the phase shifts of the cabling.

I previously was the technical lead on the current generation of the DRS Antenna Controller product line, now including the X- and Ku-band On-The-Move terminals, the FAC-50 controller for 1 to 5-meter antenna pedestals, and the FAC-750 controller for 5-meter and larger pedestals.

I designed the common software architecture that is used on both the PowerPC- based systems (COTM and FAC-50) and the Intel-based systems (FAC-750). The software is based on a custom Linux distribution using Busybox, the Xenomai real-time microkernel, and Linux 2.6.18. Part of the design for the COTM variant included a low-cost inertial navigator using MEMS gyros, a magnetic compass, and MEMS accelerometers augmented by GPS.

Another product I developed at DRS was the CTM-100C Conditioned Diphase (CDI) modem. The CTM-100 converts betwen a number of civilian and military telecommunications protocols. It incorporates an FPGA that is reconfigured on-the-fly as the user selects different conversion modes. The CTM-100C is widely deployed in military satellite vans and tactical switches.

Wasatch Communications Group
Salt Lake City, UT
Position: Managing Partner

Wasatch Communications Group was a full-service Internet Service Provider and consulting firm, one of the first in Salt Lake City. It was sold to Aros Net of Salt Lake City in eary 2000. My primary responsibilities were in the areas of system administration and software development.

My system administration responsibilities included managing a Unix network that supported WWW, SMTP Mail, Usenet News, an SQL Database, and other Internet services. I installed and configured Cisco and other routers for customers. I was responsible for network topology, security policies, and system maintenance.

Loral Communications Systems
640 N 2200 W
Salt Lake City, UT 84116
Position: Principal Engineer - Next Generation Ground Terminal

As Principal Software Developer for the Next Generation Ground Terminal, I developed the operator interface software for a high-speed air to ground digital data link. This software was network-aware and allowed for control of both the ground equipment and the airborne equipment from a single console located on either end of the data link. The software was written in C++ under Solaris (Unix) using the Motif GUI toolkit. It interfaced with, controlled, and provided the user interface for a VME chassis running the VxWorks real-time OS.

EFI Electronics
Salt Lake City, UT
Position: Consulting Engineer

I consulted with EFI on the design of an Automated Test System for high-volume production use. This system performed final programming and checkout of Uninterruptible Power Supplies. I designed and implemented the test software in C++ under MS-Windows and assisted with modifications as the product evolved.

Salt Lake City, UT 84116
Position: Principal Engineer - Test Technology

Responsibilities primarily involved the development of custom test equipment for various air-ground communications applications, including a 48-channel Bit Error Rate Test Set and two different Inertial Navigator Simulators. I developed proof-of-concept software for Ground Terminal, and lead a team that developed a Windows-based interactive test system for production test of an air-to-ground digital data link.
