Localization of nodes is very important in wireless sensor network. A localization algorithm is proposed based on TOF (time of flight) ranging and Unscented Kalman Filtering (UKF). Firstly, TOF ranging was selected to measure the distance between beacon nodes and unknown nodes. With the TOF data, the distance measurement was obtained and optimized, and an node localization method was achieved by using...
The GPS software receiver's architecture is reviewed. And a classic second order phase lock loop and the loop parameters' configuration are described. Though analyzing the total phase jitter, it is shown that under a realistic weak signal condition, the tracking loop's ability is inhibited by the noise and transient frequency jump. Then an optimal estimation based intelligent integrated tracking loop...
Multi-satellite integrated navigation system, the research focus navigation field both at home and abroad, is expected to improve the precision of positioning service and security of the information. The paper starts with an introduction of the basic concept of multi-satellite navigation system. It then follows a literature review covering mainly the current status of foreign and domestic research...
