- Abstract
In order to realize high accuracy and real-time of attitude measurement and solve the problem of high complexity of Least-squares Ambiguity Decorrelation Adjustment(LAMBDA) algorithm in Beidou attitude measurement algorithm beased on carrier phase, the C6678 multi-core digital signal processor (DSP) with TI's high-end processor is chosen as the single-apoch single-line Beidou attitude measurement platform. According to the characteristics of algorithm, the data stream mode is adopted to allocate tasks to multi-core:DSP's CORE0 is responsible for the User Datagram Protocol (UDP)communication with the Beidou receiver,the various branches of Beidou attitude measurement algorithm are assigned to other three DSP COREs implementation. Running result of the real-time data collected by OEM617D Beidou receiver on the multi-core DSP algorithm is compared with the Matlab simulation result, which shows that the design can meet the real-time and accuracy requirements of the Beidou attitude measurement.
