Application of massively parallel signal processing architectures to GPS/inertial systems

Abstract

Summary form only given. The author considers the use of a massively parallel signal processing architecture in GPS (Global Positioning System)/inertial sensors to acquire satellite signals in fractions of a second (vs. tens of seconds today), as well as the GPS-inertial synchronization and mechanization required to extend the current application of Kalman filtering to estimating and eliminating continuous-wave jammer has also been explored. Satellite signal acquisition results based on analyses, verified by simulation and live data, have been obtained for both C/A and P-code acquisition in the presence of jammer. Similar data have been obtained for tracking in a high jamming environment. All results are with the Honeywell GG1308 RLG-based IRU and an IEC GPS sensor.<>
