UK air navigation service provider NATS is about to make the first use of wide-area multilateration for aircraft surveillance in an offshore environment, going live in the North Sea with the first ...

Multilateration is the technique of using only distance measurements from stations to determine the location of a target, with no information about the direction from which this distance was measured.

One of the rather surprising omissions of FAA’s Next Generation Air Transportation System (NextGen) Implementation Plan, released in March, was that, despite its full description of the agency’s ...

Calgary International, Canada's third busiest airport, currently uses a Surface Movement Radar (SMR) for surface surveillance. As part of this project, surveillance data from the Saab Sensis ...

In the battle to improve traffic flow and prevent runway incursions, Memphis International Airport has become the front line. The engagement there involves both state-of-the-art ground-management ...

Wide area multilateration algorithms suffer from stability issues related to the fact that the reference points are nearly coplanar. This paper presents a method to ...

Abstract: Existing multilateration algorithms typically do not account for information that is previously known about the target’s position. This paper presents a method of using an a priori estimate ...

True-range multilateration is a method to determine the position of a point in space by using multiple ranges between the point and known locations (anchors). Uses ordinary least squares to solve the ...

In preparation of the implementation of the Wide Area Multilateration (WAM) Surveillance Air Traffic Management System in the Gulf of Guinea, the Nigerian Airspace Management Agency (NAMA) has held a ...
