摘要：
Researchers examine global navigation satellite system (GNSS) reliability and positioning accuracy enhancement based on fast satellite selection algorithm and receiver autonomous integrity monitoring (RAIM) in multiconstellation. The researchers demonstrate that they can improve positioning accuracy and lessen receiver computational complexity by fast satellite selection algorithm, depending on both Newton's identities and optimal satellite geometric distribution. They are also able to estimate the weighted matrix factor more accurately by considering real-time signal quality or satellite carrier-to-noise ratio, receiver thermal noise, and atmosphere transmission delay.
