Embodiment Construction
[0052] see Figure 1 to Figure 5 Shown is a specific embodiment of the present invention.
[0053] From Figure 1 to Figure 3 As can be seen:
[0054]The present invention is composed of an outdoor unit 1, an indoor unit 2 and a cable 3, wherein: the indoor unit 2 is a man-machine interaction interface, and the outdoor unit 1 includes an antenna module 1.1, an integrated service processing module 1.2, a housing 1.3, and a mounting flange 1.4. In addition, the antenna module 1.1 is placed above the housing, the integrated service processing module 1.2 is placed in the housing 1.3, the mounting flange 1.4 is placed below the housing 1.3, and the 4 are combined from top to bottom to form a whole. The cable 3 is connected with the indoor unit 1 to form the whole system.
[0055] From Figure 4 As can be seen:
[0056] The integrated service processing module 1.2 is a modular structure, including: ARM embedded processor 1.2.1, synchronous dynamic data memory SDRAM1.2.2, elect...

The invention relates to a tri-mode positioning and navigation system based on BD-1 (Beidou-1) / BD-2 (Beidou-2) / GPS (global position system). The system comprises an outdoor unit, an indoor unit and cables, wherein the indoor unit is a human-computer interaction interface, and the outdoor unit comprises an antenna module, an integrated service management module, a shell and a mounting flange. The antenna module is arranged above the shell, the integrated service management module is arranged inside the shell, the mounting flange is disposed under the shell, and the four portions are combined mutually into a whole from top to bottom. When in work, the outdoor unit respectively receives signals of the BD-1 / BD-2 / GPS, simultaneously transmits the signals emitted from the BD-1, and completes the functions of radio frequency management, AD (analog-digital) conversion, baseband processing and positioning resolve, and then sends a result to the indoor unit to achieve a human-computer interaction.
Description
technical field [0001] The invention relates to a positioning and navigation system, in particular to a positioning and navigation system based on Beidou-1 / Beidou-2 / GPS three modes. Background technique [0002] Since its inception, GPS has fully demonstrated its dominance in the field of navigation and positioning, and many fields have undergone revolutionary changes due to the emergence of GPS. [0003] Although the GPS satellite navigation and positioning system of the United States can cover the whole world and realize all-weather and all-day navigation, they are all controlled by foreign military forces, and GPS provides positioning services with different accuracy for different levels of users. In areas of military conflict, the United States may turn off GPS in some areas out of consideration of its own interests. Therefore, despite the huge capital required for development and the long cycle, my country is still actively developing its own satellite positioning syst...
