AN/WRN 6(V)
The AN/WRN 6(V), shown in figure 8-30, computes accurate position
coordinate, elevation, speed, and time information from the signals
transmitted from GPS satellites.
Accuracy: The AN/WRN 6(V) will provide positions accurate within
100 meters in the unencrypted mode and positions accurate to within 16
meters or less in the encrypted mode. At all times, if possible, the
AN/WRN 6(V) should be operated in the encrypted mode.
Operating Procedures: Specific operating instructions for the
AN/WRN 6(V) are contained in NAVY SPAWAR publication EE170-
AA-OMI-020/WRN6. All Quartermasters should become well versed in
the contents of this publication.
