Abstract 
With the wide application of global Navigation satellite System (GNSS), satellite navigation receiver is the core equipment for accurate positioning and navigation, and its performance optimization and design innovation are of great significance for improving navigation accuracy and expanding application range. This paper aims to discuss the optimal design of satellite navigation receiver and its application in different fields, analyze the key technologies to improve the performance of the receiver, and look forward to its future development trend. By receiving and processing signals from satellites, the satellite navigation receiver realizes the functions of accurate positioning, speed measurement and time synchronization for ground users. With the progress of science and technology and the growth of demand, the performance requirements of satellite navigation receivers are also increasing. Therefore, optimizing the design of satellite navigation receiver to improve its anti-interference ability, positioning accuracy and signal processing ability has become one of the hot spots in the current research. The optimal design of satellite navigation receiver mainly includes hardware design and software algorithm. In terms of hardware design, the sensitivity and dynamic range of the receiver can be improved by using high-performance RF front-end, digital signal processor and low noise amplifier. At the same time, the multi-channel parallel processing technology can significantly improve the data processing capability and real-time performance of the receiver. In terms of software algorithm, the anti-interference ability and positioning accuracy of the receiver are improved by optimizing the signal acquisition, tracking and positioning algorithms. In addition, modern signal processing techniques, such as adaptive filtering and multipath suppression, can be used to further improve the performance of the receiver. Satellite navigation receiver is widely used in transportation, agriculture, surveying and mapping, military and other fields. In the field of transportation, satellite navigation receivers can provide accurate positioning and navigation services for vehicles, ships and aircraft, improving transportation efficiency and safety. In the field of agriculture, satellite navigation receivers can be used in precision agriculture operations, such as sowing, fertilization and harvesting, to improve agricultural production efficiency. In the field of surveying and mapping, satellite navigation receivers can be used for high-precision measurement and map production, providing strong support for urban planning, infrastructure construction and environmental monitoring. In the military field, satellite navigation receivers can provide important support for combat command, weapon guidance and intelligence reconnaissance. With the continuous development of science and technology and the continuous growth of demand, satellite navigation receivers will face more challenges and opportunities. In the future, the optimal design of satellite navigation receivers will pay more attention to performance improvement and cost reduction to meet the needs of a wider range of applications. At the same time, with the continuous emergence of new technologies such as 5G and the Internet of Things, satellite navigation receivers will be combined with these new technologies to provide more accurate, efficient and intelligent services for more fields.
