AN/WRN-6(V) Satellite Signals Navigation Set

reflected signals to reach the navigation set at different times than the original signal. The reception of multipath signals may cause errors in the navigation set calculations. The AN/WRN-6 navigation set makes operators aware of multipath errors by a “fail” or “warn” message and/or fluctuations in the carrier-to-noise ratio. Multipath reception may be corrected by changing the ship’s position. AN/WRN-6(V) Satellite Signals Navigation Set The Satellite Signals Navigation Set AN/WRN- 6(V)computes accurate position coordinates, elevation, speed, and time information from signals transmitted by NAVSTAR Global Positioning System (GPS) satellites. In the P mode, it has an accuracy of 16 meters. In the C/A C/A mode. it has an accuracy of 100 meters, though better results have been obtained by individual users. The AN/WRN-6(V), shown in figure 1-13, operates in three modes. The “Initialization” mode is part of the set start-up. During initialization, the operator tests current position, date, and time data, either manually or from other equipment. The data entered is used to speed up satellite acquisition. “Navigation” is the normal operating mode. During the navigation mode, the set receives satellite data, calculates Figure 1-13.—Satellite Navigation Set AN/WRN-6(V). 1-17
