Description / Abstract:
PURPOSE AND SCOPE
This Technical Specification document specifies the minimum
performance requirements for a Wide Area Multilateration (WAM)
System that is part of a system providing airspace situational
awareness to air traffic controllers and other users within the
European Air Navigation Region.
In the frame of this document the WAM system is primarily
intended for ATM in the ECAC area to provide, in both high and low
density environments, the following air traffic surveillance
services:
• 3 NM horizontal separation
• 5 NM horizontal separation
A WAM System compliant with this Technical Specification will be
compatible with all relevant ICAO, EUROCONTROL and EUROCAE/RTCA
specifications [REF1 - REF16].
It is recognised that a WAM system may also provide an ADS-B
data reception and handling capability, but consideration of such
capability is outside the scope of this document. More information
on ADS-B ground station capability can be found in
[REF16].
