exactly where to find the best possible replacement).

Three satellites are required for two-dimension positioning (which determines

position only) and four satellites are required for three-dimension positioning

(to determine position and elevation).

7.3.1 ACCURACY

In general, an SPS receiver can provide position information with an error of

less than 25 Meters and velocity information with an error of less than 5 Meters

per second. For applications that require much greater accuracy the effects of

SA and environmentally produced errors can be overcome by using a tech-

nique called Differential GPS (DGPS), which increases over-all accuracy.

7.3.2 WAAS

The Federal Aviation Administration (FAA), in cooperation with other DOT

organizations and DOD, is augmenting the GPS/SPS with a satellite-based Wide

Area Augmentation System (WAAS). WAAS will provide a signal-in-space to

WAAS compatible receivers to support en route through precision approach

navigation. After achieving initial operational capability, WAAS will be incre-

mentally improved to expand the area of coverage, increase the availability

of precision approaches, increase signal redundancy and reduce operational

restrictions.

7.3.3 DIFFERENTIAL GPS

Differential GPS (DGPS) uses a GPS receiver at a fixed point with a known

position of sub-meter accuracy. This is the control unit. The receiver collects

data for all visible satellites and computes predicted satellite ranges, which are

compared with actual ranges. The difference is the satellite range error, which

is converted to correction signals for use by a roving receiver.

It is assumed that this correction will be the same for other GPS receivers that

are in the same area and are using the same satellites for positioning. If the

correction is communicated to other receivers in the area (usually by a beacon

on the same site), the range error can be removed from satellite signals and

precise fixes calculated by these receivers.

It should be noted that not all data errors can be corrected in this way. Errors

that are caused by receiver noise (which is inherent in any GPS receiver) and

multipath problems cannot be eliminated with differential corrections.

(Multipath errors occur when the receiver’s antenna “sees” the reflections of

signals that have bounced off of surrounding objects.)

Using DGPS to eliminate the effects of correctable errors requires that the

user’s GPS receiver be connected to a compatible differential beacon receiver

and be within range of the broadcasting beacon. The differential beacon re-
