Guardian
Air Traffic Control System. Focused primarily in the Flight
Data Management area, in an Ada UNIX environment:
- Designed and conducted software component tests and system-wide
regression tests.
- Prepared/conducted formal acceptance tests for customers (China,
Saudi Arabia, Indonesia)
Unisys GSG Canada |
3.5 Years |
Software Engineer
Worked on the
Canadian
Patrol Frigate Program, a distributed Naval
command and control system. Areas of responsibility included
Hull-Mounted Sonar, Maintenance Test, and Simulation modules, in a
CMS2-UNISYS 1100 environment:
- The target system was a network of small ("mini", as opposed to
"mainframe") hardened / militarized computers, with very limited memory,
on a warship. The development system was a mainframe where we wrote and
compiled the code, transferred the binaries onto a portable disk drive
cartridge, and then installed the cartridge in the target network for
testing on the target devices.
- Both the target mini-computers and the mainframe were products of
UNISYS, and the whole software/hardware environment was proprietary. The
mini CPUs had their own UNISYS instruction sets and corresponding
assembly language (called ULTRA-16 - all I/O was coded in assembly) and
the high-level language used was also a UNISYS product called CMS-2
(similar to Pascal).
- I contributed to several modules, but the main one was that of the
Hull-Mounted Sonar. This module talked directly to the sonar hardware,
accepting sensor data from the sonar and issuing commands to the sonar.
There was also a display component, giving the sonar operator a visible
indication of the physical state and mode of the sonar, and the location
of target echos. There was also a simple tracker, which extrapolated
recently reported target positions so as to predict future target
position. A typical real-time software kind of application.
- I extensively re-wrote the control software for the Hull-Mounted
Sonar, correcting a wide range of software problems, ranging from
low-level interface and device-control malfunctions through sonar
tracking anomalies and operator interfaces.
Lieutenant, Combat Systems Engineer
- One year of sea time as a Combat Systems Engineer. Responsible for
the safety and operation of the ship. Supervised a duty watch of up to
40 crew.
- At Fleet Software Support Center, designed, coded, and implemented a
PC-based "Configuration Status Accounting" database to track software
changes.
