The world’s leading supplier of ground based air navigation aids needed additional software expertise to support them in their ongoing maintenance and development of the front-end processing software for their direction finding product.
The DF system provides accurate navigation information including positional data without the need for special equipment other than standard VHF or UHF radio systems.
LeoTel Software Systems worked as a software partner providing software engineering services directly to the client as project needs demanded.
LeoTel engineers were deployed as a software development sub-team, working closely with the systems and project engineers supporting the main ongoing activities viz.:
a) Diagnosis and resolution of fault reports in the existing software system;
b) Specification and estimation of new features required by new contract bids;
c) Development and validation of new features required by new contract wins.
The LeoTel team provided a varying engineering load as demanded by project activity. By ensuring the continuity of the engineers providing the service, LeoTel was able to build up considerable knowledge of the software systems, and consequently could ensure consistent and rapid response to ongoing demands as the need arose.
In addition, LeoTel provided technical consultancy on an ad-hoc basis, allowing the client to respond to customer enquiries, particularly on new project bids, about new technologies.
The direction finder front-end processing software system is a management system for single or multi-site management of direction finding equipment. It scales effectively from a single site installation through to significant multi-site installations, with remote access facilities and sites requiring network overview facilities.
The core software is written in C++ and runs on the QNX Unix-like real time operating system. The software system leverages the power of the QNX QNET native network protocol to provide transparent distributed processing throughout the front-end processor network. Additional software components can be attached to the front-end processor network to provide monitoring of active bearings, auto-triangulation of transmitting aircraft, and many other features.
