[0032] The UWB+ satellite fusion iron shoe positioning terminal fusion positioning system combines the advantages of two positioning technologies, so as to realize more accurate and reliable positioning in various environments. UWB (ULtra-Wideband) and GNSS are two different wireless positioning technologies, each of which has unique advantages and limitations. By combining these two technologies, a higher precision and more reliable positioning solution can be achieved.

[0033] The surfaces of the two mounting side plates 31 are provided with two mounting holes 6, and the mounting holes 6 are elliptical holes.

[0039] The locator body 1 is provided as a high-protection locator;

[0040] The high-precision positioning system comprises UWB and GNSS;

[0041] It should be noted that UWB is a short-range, high-precision wireless communication technology that achieves high-precision time measurement by sending and receiving extremely narrow pulse signals, thereby achieving accurate positioning. UWB technology has the following characteristics:

[0042] High precision: UWB can achieve centimeter-level positioning accuracy, suitable for applications with extremely high precision requirements.

[0043] Low power consumption: UWB devices use short pulse transmission, with low duty cycle, so the power consumption is small.

[0044] Strong anti-interference: Because the bandwidth of UWB signal is very wide, it has strong anti-interference ability to multipath effect.

[0045] High safety: The power spectral density of UWB signal is low, difficult to intercept or interfere with other systems.

[0046] Overview of GNSS technology

[0047] GNSS is a satellite-based global positioning system that can provide positioning services in open outdoor areas. The main features of satellite positioning technology include:

[0048] Global coverage: GNSS system consists of multiple satellites, which can provide positioning services worldwide.

[0049] Portability: GNSS receivers are small and portable, easy to integrate into various devices.

[0050] Real-time: GNSS can provide real-time positioning information, suitable for dynamic tracking and navigation.

[0051] Advantages of fusion positioning

[0052] Combining UWB and GNSS technologies can leverage their respective strengths and provide a more powerful and flexible positioning solution:

[0053] Seamless coverage: GNSS is suitable for open outdoor environments, while UWB is suitable for indoor or environments where GNSS signals are disturbed. Combining both can achieve seamless indoor and outdoor positioning coverage.

[0054] Improved accuracy: The high-precision characteristics of UWB can compensate for the lack of accuracy of GNSS in certain environments, improving overall positioning accuracy.

[0055] Enhanced reliability: In cases where GNSS signals are blocked or disturbed, UWB can provide stable positioning information, enhancing the reliability of the system.

[0056] Expanded application scenarios: Fusion positioning technology can be applied to more scenarios, such as indoor positioning, personnel tracking, security monitoring, etc.
