[0002] Beidou second-generation satellite positioning and navigation system is a passive satellite positioning and navigation system developed on the basis of Beidou first-generation active positioning. The satellite signal positioning device for Beidou second-generation navigation system is an integrated design connected with a handheld terminal. The structural design has not met the requirements of miniaturization and low power consumption, and it is impossible to place the satellite signal positioning device for the Beidou second-generation navigation system alone in a place with high signal strength to receive signals, making it lightweight, portable, and battery life. There is a great limitation in signal receiving strength; and miniaturization is facing new problems. How to eliminate electromagnetic interference between devices in a small space and improve electromagnetic compatibility is an urgent problem to be solved

The invention provides a small and portable satellite signal positioning device for a Beidou second-generation navigation system. The device comprises a lower shell, a battery, a battery cover, a circuit board, a Beidou antenna and an upper shell in sequence from bottom to top. The circuit board is in a receding design. The two sides of the circuit board are provided with shielding covers for isolation. According to the satellite signal positioning device for the Beidou second-generation navigation system, a Beidou module is placed in one shielding cover, a system circuit is placed in the other shielding cover, the Beidou module and the system circuit are arranged on the two sides of the circuit board respectively, and the circuit board is of the receding design so as to reduce the electromagnetic interference. The satellite signal positioning device for the Beidou second-generation navigation system is separated from an original Beidou system with the large size, and can be independently placed at the place with the strong signal, the signal receiving quality is greatly improved, and the wireless invisibility is good. The satellite signal positioning device is small in size and convenient to carry.
Description
technical field [0001] The invention relates to a positioning device, in particular to a satellite signal positioning device for the Beidou second-generation navigation system. Background technique [0002] Beidou second-generation satellite positioning and navigation system is a passive satellite positioning and navigation system developed on the basis of Beidou first-generation active positioning. The satellite signal positioning device for Beidou second-generation navigation system is an integrated design connected with a handheld terminal. The structural design has not met the requirements of miniaturization and low power consumption, and it is impossible to place the satellite signal positioning device for the Beidou second-generation navigation system alone in a place with high signal strength to receive signals, making it lightweight, portable, and battery life. The strength of signal reception is very limited; and miniaturization is facing new problems. How to elimin...
