Designed and developed the spacecraft command database server.
Ported EPOCH's proprietary-protocol-based, telemetry processing applications into a
TAO/ACE CORBA environment.
Upgraded telemetry processing and simulation software for new satellite types.
Designed and developed a Scheme-/CORBA-based parameter calculation program that directly
executes the nearly 800 Scheme equations supplied by the satellite manufacturer.
Created a Python tool to convert customers' existing display page definitions (which used
ISI's proprietary page description language) to XML for importation by our Windows-based
EPOCH Client.
Developed my own lightweight CORBA library and code generator for independent testing of
application interfaces.
Wrote numerous tools in C, C++, and Python on Unix and Windows that allow on-site and
remote monitoring and control of our system for testing purposes.
Software developer on the distributed, object-oriented successor (Version 3) to ISI's
EPOCH satellite control system.
(
1996 - 2001)
Ported legacy telemetry processing applications into a networked C++ environment.
Maintained and enhanced the telemetry processing and simulation software, including
upgrades for new satellite types.
Developed a C++ network communications library.
Wrote networked interfaces to and a software emulator for the IN-SNEC CORTEX Telemetry
and Command hardware units.
Developed numerous tools in C, C++, Tcl/Tk, and Java that allowed on-site and remote
monitoring and control of our system for testing purposes.
Software developer on NASA's EOSDIS Test System (ETS), which simulates various external
interfaces to the Earth Observing System Data and Information System (EOSDIS).
(
1995 -
1996
)
Added ETS enhancements to selected LZP-II software applications (see below).
Participated in the design of a telemetry data simulator to be implemented in C++.
Developed an extensible, FTP server toolkit used to implement an embedded FTP server that
accesses files via an in-house file system.
Created an embedded, user-programmable HTTP server that permits our systems to be
monitored and controlled from a World Wide Web browser.
Software developer on LZP Phase II, a NASA R&D project to build a high-rate (50Mbps)
packet processing system based on VLSI hardware and embedded software running on multiple
68040 processors.
(
1993 - 1995)
Developed a number of library functions used to help port the existing PDOS-based
software to VxWorks and to allow the testing of embedded software under UNIX.
Developed an extensible I/O package that dynamically loads application-specific, user-
level device drivers.
Used the I/O package to add device-independence to the programs that sort and assemble
packets into data sets.
Developed an embedded, user-programmable debugger and a workstation-based, user-
programmable GUI used during system integration and test.
Software consultant
to Computer Sciences Corporation (Laurel, MD) on SIR-C/X-SAR, an ESA
project to build a distributed, VAX-based control center for a shuttle-borne radar
instrument.
(1992 - 1993)
Ported parts of the UNIX-based TPOCC software (see below) to VMS.
Contributed to the writing of the customer's Architectual Design Document and of our own
Detailed Design Document.
Used prior TPOCC, C, UNIX, and VMS experience to assist other members of the group in the
design, code, test, and integration of various subsystems, including the X/Motif-based
GUIs, the real-time telemetry and command software, and the database management utilities.
Wrote many general-purpose and project-specific library routines.
Developed tools and simulators used to test our software and to integrate it with our
customer's systems.
Redesigned and coded the distributed monitor program that arbitrates the primary/backup
status of the redundant telemetry processors.
Supported the reverse engineering of the existing TPOCC software and, when time
permitted, worked on upgrading that software to ANSI C standards.
Programmer/analyst for TPOCC, a NASA R&D project to build a generic satellite control
center based on distributed UNIX workstations and readily adaptable to new missions. (1987
- 1992)
Developed an extensible, network-based, command language (TSTOL) interpreter server using
UNIX LEX and YACC; the interpreter is now in use at a number of sites, independently of
TPOCC.
Made significant contributions in the areas of display generation, spacecraft commanding,
and telemetry processing.
Initiated and wrote 75% of the project's shared software library, as well as most of the
utility programs.
Issued numerous memos that allowed other members of our group to quickly come up-to-speed
on the intricacies of UNIX and TPOCC.
Participated in the system and comprehensive design presentations and my self-imposed,
software documentation standards were incorporated in the project's standards.
Edited the TPOCC programmer's reference guide, a large part of which I wrote myself.
