AI Technical Summary
Technical Problem
In the presence of interference, existing technologies struggle to accurately measure the code phase and carrier phase of satellite signals, leading to a decrease in positioning accuracy.
Method used
By using different bandwidths to measure satellite signals, code phase and carrier phase measurements are performed with and without interference, cycle slips in carrier phase measurements are avoided, and a suitable code phase is selected when interference is present to improve measurement accuracy.
Benefits of technology
It improves the accuracy of satellite signal measurement, avoids the decrease in positioning accuracy due to bandwidth changes, and enhances positioning accuracy in interference environments.
