Abstract : 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, preamplifier unit, and an optional printer. The navigation program is permanently programmed on read-only memory chips. 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 1 the design and operating principles of the SRN-19(XN-1) are discussed. Volume 2 documents the Mk 2 Mod 2 computer program; Volume 3 consists of the mechanical drawings that describe the SRN-19(XN-1) package configuration. (Author)
