Abstract:
The Federal Aviation Administration (FAA)

Surveillance and Broadcast Services (SBS) Program

Office and the Colorado Department of

Transportation are implementing Wide Area

Multilateration (WAM) in Non-Radar Airspace

(NRA) to improve air traffic services at and around

routes and fixes that support operations at

Hayden/Yampa Valley (HDN), Craig-Moffat (CAG),

Steamboat Springs/Bob Adams Field (SBS), and

Garfield County Regional - Rifle (RIL) airports. In

particular, the lack of comprehensive radar

surveillance at and below 10,000 ft. in these regions

requires controllers to use procedural separation

standards for the Instrument Flight Rules (IFR)

arriving/departing aircraft. While this is a safe means

of providing service, it is inefficient for current traffic

and especially for expected demand growth.

Wide Area Multilateration is a distributed

surveillance technology that utilizes a constellation of

ground stations to provide surveillance coverage

within a defined region. This technology makes use

of signals transmitted from Air Traffic Control Radio

Beacon System (ATCRBS) (Modes A and C) and

Mode S transponders, in response to interrogations.

The Mode S transponders also provide the squitter

message once per second.

The implementation, certification, and

commissioning of WAM would enable air traffic

controllers to apply more efficient separation

standards for aircraft operating in the affected

airspaces. For this operational environment, with

WAM as the surveillance technology, the FAA seeks

to achieve 5 NMI lateral/longitudinal separations.

This paper describes the technical results from

the data modeling, controlled flight test, and targets

of opportunity analysis for the WAM sensor

constellations near HDN and RIL to support

separation standards within the Host Computer

System (HCS) automation platform environment at

Denver Center (ZDV). Comparative analysis was

conducted between WAM and Secondary

Surveillance Radar (SSR) to evaluate and validate

WAM performance to support separation services.
