HARRIS SOFTWARE DEVELOPMENT EXPERIENCE

Harris supplied the earth station network over which the NBC television network

distributes its video feed to affiliates. The master station required a network

control terminal over which all 176 stations in the network can be controlled.

Designed the human interface for the network maintenance terminal. Developed a

generalized command line parsing algorithm that accepts one line commands but

automatically drops into prompt mode if a command is found to be invalid. A

command logging function assists in the development of macro-commands that can

enable the entire network of 176 earth stations to change satellites and re-

tune by submitting a command script. The concept of state table driven software

was utilized. Generated code in PLM-86 on an INTEL RMX host. Produced software

documentation to accepted standards.

HARRIS NEW PRODUCT DEVELOPMENT EXPERIENCE

Designed the monitor and control subsystem of the HARRISAT ALPHA earth terminal

(a Ku band data terminal). Developed hardware and software interface

specifications, designed the CPU, designed a redundant serial bus interface,

designed analog data acquisition circuits, and circuits that isolate faults in

RF equipment. Upon completion of the hardware design, programmed this product

in assembly language to comply with specified customer interfaces.

Responsibilities included technical liaison with customers, and system testing

for compatibility with customer software.

Managed the product development of the HARRISAT Protection Switch. This

microprocessor based device enables two of the HARRISAT ALPHA earth terminals

mentioned above to operate in a one-to-one redundant configuration. Performed

the hardware and software development, led others in the design of mechanical

packaging. Building upon previous designs, this project was taken from concept

to working model in four weeks. The first two finished products were shipped

eight weeks after the start of development. Also designed five other redundancy

control switches, one for upconverters two for downconverters, one for low

noise converters, and one for satellite modems.

Managed the development of a data-link protocol converter to act as a gateway

between a TANDEM Computers Inc. packet switch and a Harris proprietary network

for controlling satellite equipment.
