Industries Aerospace (Newmark)
Software Engineer: Automatic flight control system (AFCS) for PZL SOKOL helicopter. AFCS based on proven Sea King system. Ported existing CORAL code from an unsupported compiler to XGC on Sun Ultra / Solaris 8.0. Code targeted at MC68020. AFCS design / code updated to utilise additional position data from GPS input. Software development / debugging using microVIEW-G symbolic debugger. Software design and coding (C à Atmega128 micro controller) for an interface card to receive (via RS232 / ARINC 429) and format positional information from a GPS I/F for use by AFCS.
Software
Engineer: Cabin pressure control system for Embraer ERJ 170/190. ‘C’ code
generation (Tasking 166 compiler targeted at a C167 microcontroller) from UML
design. Hardware/software integration test specification produced to satisfy the
objectives of DO-178B for level ‘A’ software. Traceability using DOORS;
configuration management with ClearCase.
Delphi
Delco Automotive Systems:
Satellite
Digital Audio Receiver (SDAR): Principal Software engineer responsible for
design and coding (‘C’ è
NEC V850, embedded) of an in-vehicle SDAR system for XM and Sirius satellite
radio. Satellite broadcast content is advanced RDS type subscription orientated
programming allowing service selection / ‘navigation’ (both audio and data)
by program genre / data type. Communication between radio head and SDAR via
class 2 vehicle bus (General Motors). Software requirements and design derived
iteratively from satellite service layer protocols and API specifications.
Software integration and test using NEC ID850 I2ICE, APTIX / FPGA IC
simulation. Received two Delphi Automotive Systems awards; (1) Performance
Quality Award for developing service providers’ satellite broadcast protocols
and (2) Extraordinary Work and Customer Focus whilst working on site with XM
developing the first SDAR to be fitted in 2001 model year Cadillacs.
