Extract

This paper and the following three papers were presented at the Institute's NAV-96 Conference, “Global Navigation — Where are we now?” The Conference was held in London In November 1996. Copies of the full proceedings may be obtained on application to the Director, price £35 for members and £50 for non-members.

The National Air Traffic Services (NATS) in London require data on the performance likely to be achieved by the navigation system on board aircraft flying in UK airspace. To that end the performance of three different GPS receiver types (all designed for aviation use) have been examined. This paper details the result of that work. The achieved Mean Time Between Failures (referred to here as ‘Outages’) MTBO is presented along with the nature of some of the failures that have been encountered. The paper concludes with the operational implication of the findings.
