The AN/SRN-19(XN-1) Radio Navigation Set was developed by The Johns Hopkins University Applied Physics Laboratory under U.S. Navy sponsorship to meet the need for a simplified, low-cost navigation set of moderate accuracy. The SRN-19(XN-1) provides the advantages of the Navy Navigation Satellite System to small vessels of the Navy and to commercial ships for which the existing equipment is too expensive. The SRN-19(XN-1) is a single channel (400 MHz), integral doppler navigation set that is self-contained except for the antenna, Pre-amplifier unit, and an optional printer. The navigation program is permanently programmed on read-only memory ships. Satellite navigation fixes taken by this equipment are used to update continuous dead reckoning positions as obtained from ship's motion data (course and speed) that are input to the set from the ship's gyrocompass and the EM log. In Volume I the design and operating principles of the SRN-19(XN-1) are discussed. Volume II documents the Mk II Mod 2 computer program; Volume III consists of the mechanical drawings that describe the SRN-19(XN-1) package configuration. (Author)
