Abstract

This paper provides the detail design of a navigation computer, which is designed specifically for an integrated SINS/GPS navigation system. According to the function of the navigation computer, the design is described in three modules: data acquisition module, signal processing module, and communication module respectively. The navigation computer system selects TMS320VC33 as its CPU and ADS1217 as its A/D convertor. With the powerful Digital Signal Processor and highly precise A/D convertor, it is demonstrated through experiment that the precision of data acquisition module is 16 bits, meanwhile, the time used for completing the whole SINS algorithm is less than 1ms.
