This paper focuses on a new approach for the calibration of IMU misalignment angles. Firstly the rigorous mathematic model of IMU misalignment describing the relationship among IMU output angles, misalignments and exterior orientation angular elements is discussed, then one-step and two-step these two fundamental calibration methods are introduced. According to the idea of two-step calibration a rigorous...
An integrated location algorithm using satellite location and wireless sensor networks (WSN) is put forward to solve the issues of seamless location both indoors and outdoors in a pervasive computing environment in this paper. Pseudorange observation data of global positioning system (GPS) and distance observation data of WSN are utilized to carry out positioning. Simulation results show that comparing...
The pseudolite augmenting GPS technique can effectively improve the geometric strength of GPS positioning solution, which also enhance the availability, reliability and precision of GPS. Using integrated GPS and pseudolite signals as navigation tools in outdoor situation will contribute to a promising application, and there are some obstructions that should be concerned. In this paper, we have a theoretical...
Either as a significant augmentation of GPS system, or as an independent system for indoor positioning, pseudolites augmenting GPS technique has become an exciting technology whose potential can be explored for a wide range of positioning and navigation application. Indoor positioning using multiple pseudolites signals, however, comes up against a number of obstacles, and there are some challenging...
