Abstract

The geolocation of a hostile radar emitter by coordinated data sharing within an airborne community requires a common navigation solution accurate to less than one foot, and relative timing to under a nanosecond.  BAE SYSTEMS has developed approaches combining standard Link-16 hybrid inertial navigation and differential GPS processing which can provide such performance.   Since Link-16 navigation depends on good TOA measurements, estimation of atmospheric delay is vital.  A simple algorithm for doing so is described. In order to further refine the navigation and time synchronization accuracy of the community, a DGPS approach using pseudorange measurements from all satellites within view has been developed. Three elements of position, one of time, and one of frequency are jointly estimated. The algorithm can provide the required navigation and time accuracy for emitter location and remote time transfer.  

Biography

Mr. Reiss is a System Engineer and Senior Member of the Technical Staff at BAE SYSTEMS CNIR Division in Wayne New Jersey, and has been employed there since March 1970.  His primary responsibilities there have dealt with design, integration and testing  of spread spectrum communication and navigation systems, including Link-16 and the Multinational Information Distribution System (MIDS). Other interests include  the application of integrated multiplatform navigation and time synchronization to situation awareness, emitter location, weapon guidance and control, and other applications of Network Centric Warfare (NCW).  He received his BSME from Cooper Union, New York in 1963, and an MSME from New York University in 1965.
