The GPS receiver can calculate its position based on the signals received from satellite using different codes, such as P1, P2, and P3. The P3 code provides more accurate positioning information as compared to other codes. However, the accuracy of GPS is influenced by different factors such as ionospheric delay, multipath, and atmospheric interference. To mitigate these effects, cooperative positioning and time delay correction techniques can be used to improve the accuracy of GPS.Objective:The objective of this project is to analyze and implement cooperative positioning and time delay correction for GPS P3 code receivers. This includes the development of algorithms for timely correction of satellite clock bias, ionospheric delay, and tropospheric delay. The project aims to improve the accuracy of P3 code receivers by integrating information from multiple GPS receivers and utilizing the common view of satellite signals.Methodology:The project will use cooperative positioning techniques to improve the accuracy of GPS receivers. The cooperative positioning technique uses the common view of satellite signals received by multiple GPS receivers to estimate the location of each receiver. The method involves the comparison of the code phase measurements of the received signals from different satellites by different receivers. The P3 code phase measurements will be used for this purpose.The project will also implement time delay correction techniques to compensate for the delay caused by different 精品文档---下载后可任意编辑factors such as ionospheric and tropospheric delay. This involves the estimation of the delay using different models and techniques, which will be implemented in the software.Conclusion:The proposed project aims to improve the accuracy of GPS P3 code receivers. The cooperative positioning and time delay correction techniques will be used to reduce the error caused by different factors such as ionospheric and tropospheric delay. The project will involve the development of algorithms and software implementation of the techniques.
