Abstract

Data Fusion Corporation (DFC) proposes the development of a prototype combat positioning system that will reduce fratricide, increase situational awareness (SA), and enhance combat effectiveness for UGS-to-Soldier based CID applications. The system design will use GPS, Tactical Unattended Ground Sensors (UGS), a modified-mobile adhoc network MANET, local ranging signals and a mesh network that will provide sub-meter position information, velocity, time (PVT) as well as ID. The sub-meter position is obtained using DFC’s legacy innovative positioning algorithms that uniquely combine (in a weighted least squares sense) lower accuracy absolute positions with highly accurate relative positions. Furthermore, DFC takes advantage of the mesh rigidity where appropriate. The minimal configuration can be a mixed network of dynamic nodes with or without GPS. GPS receivers only need be single carrier (L1) receivers processing the lower accuracy CA signal. This can be accomplished without any infrastructure. Should L1L2 P(Y) code receivers, and infrastructure be available additional accuracy and robustness can be gained. DFC will leverage its legacy positioning algorithms, GPS signal generator software and GPS soft¬ware receiver (Kober, W., 2004), implemented on a Field Programable Gate Array (FPGA), to develop this CID system. The original GPS software receiver design was sponsored in part by AFRL/SN, AFRL/MN and USASMDC.
