IMS/GPS integration with a novel real-time system platform for inertial data estimation

Consider about the trade-off between cost and accuracy, lots of works investigate into the inertial measurement system (IMS) and Global Position System (GPS) fusion. However, with the necessary to insure the long-term on-board working precision it results in a complication between the time-consuming and complex calculation in the system design. Therefore timing has become a critical problem in the hardware design. Nowadays more and more applications require not only the accuracy but also the rapid response. This paper addresses a new way to separate the system design into three modules and applied into a parallel structure, like Microprocessor without Interlocked Pipeline Stages (MIPS) to realize the real-time performance. Using the System-on-Chip (SOC) technology, the system platform can adapt the timing consummation and signal frequency between each module, in order to estimate the velocity and position of vehicle in real-time.
