On April 29, the National Geospatial Intelligence Agency (NGA) posted a request for information for RENAV. Responses are due by 12:00 p.m. Eastern on May 29.
NGA’s Maritime Safety Office manages the Narwal which produces a classified bathymetric database and a series of special graphics for the Navy’s Chief of Naval Operations (CNO). Raw navigational data is processed with custom software to develop a statistically corrected and adjusted track. The corrected track is then merged with digitized echogram data to produce accurately positioned bathymetric sounding data. The special graphics are compiled with commercial software using the sounding data along with a variety of both classified and unclassified sources such as other bathymetric data, standard nautical charts, imagery data, and foreign source data.
The INS Kalman Filter Engine (INS KF Engine) software is a government -off-the-shelf (GOTS) application developed by Johns Hopkins University/Applied Physics Lab (JHU/APL) that integrates and enhances the RENAV software which is a subset of the Narwal baseline. The application requires functional enhancements and adaptive maintenance to meet maritime safety requirements. The INS KF Engine may be referred to as RENAV enhancement throughout this document.
