| Abstract: | We introduce and analyze the architecture of GPS receivers.Based on their principle,there are several types of GPS receivers,continuous receiver,sequential receiver and multiplex receiver.According to the application of GPS receivers,they also have three types,high-precision receiver,navigation receiver and time transfer receiver.We also describe the performance standard of GPS receivers related to GPS satellites signals errors.With GNSS development,multi-system dual-frequency receivers present better performance than traditional receivers.Therefore,they are the new development trend of GPS receivers. |
