Beidou-3 is the world's first satellite navigation system to provide tri frequency signal services. The use of dual frequency signals in satellite navigation systems can reduce the impact of ionospheric delay, while the use of tri frequency signals can construct more complex models to eliminate high-order errors in ionospheric delay and improve the efficiency of… Continue reading How does a tri band signal service satellite navigation system compare to dual band GPS
Bluetooth Beacon is a small wireless device based on Bluetooth Low Energy (BLE) technology. Its working principle is that Bluetooth beacon send Bluetooth signals containing their own identification and related data at a certain frequency. These signals typically contain the unique identifier of the beacon (such as UUID, Major value, and Minor value) as well… Continue reading What are the characteristics and application scenarios of Bluetooth beacons
When the Bluetooth function in the mobile device is turned on, it will receive signal data sent by the iBeacon base station. After receiving the signal, the device estimates the distance between itself and the iBeacon base station based on the Received Signal Strength Indication (RSSI). Through the cross coverage and distance calculation of multiple… Continue reading IBeacon passive positioning technology principle, precise indoor positioning and navigation
The Beidou system consists of three parts: space segment, ground segment, and user segment. The space segment consists of a constellation of satellites with different orbital planes, including 3 GEO satellites, 3 IGSO satellites, and 24 MEO satellites. The ground segment includes several ground stations such as the main control station, time synchronization/injection station, monitoring… Continue reading The composition characteristics and advantages of the Beidou system
Accurately and real-time understanding of the location and status of materials in enterprise material management is crucial for improving operational efficiency, reducing costs, and ensuring smooth production. However, traditional material management methods often suffer from problems such as inaccurate information, untimely updates, and difficulties in searching, leading to material waste, production delays, and other situations. Therefore, we propose this material positioning management solution, aiming to achieve precise positioning and efficient management of materials through advanced technological means.

The Beidou Satellite Navigation System is a satellite navigation system independently built and operated by China, providing high-precision positioning and navigation services for global users. The Beidou positioning satellite can provide high-precision positioning, navigation, and timing services, and is widely used in many fields such as transportation, surveying, and rescue. The Beidou positioning satellite achieves global coverage, precise positioning and navigation, and assists in intelligent travel, agricultural production, and disaster relief work.
In response to the need for high-precision positioning in positioning scenarios, and to overcome the adverse effects of indoor environment on positioning accuracy, this project proposes a weighted correction positioning algorithm combining trilateral measurement positioning. The positioning system first uses the trilateral measurement positioning algorithm to estimate the initial position of the user, and then combines the position estimation obtained from the initial positioning with the user's position
The actual constellation PDOP value of the Beidou satellite navigation system has reached the international leading level. The indicator parameters of a navigation constellation mainly include the number of available satellites in orbit and the Position Dilution of Precision (PDOP). The number of available satellites determines the coverage of the constellation's navigation signal, while PDOP is an important indicator used to measure the positioning accuracy of satellite navigation systems and the geometric strength of observation values, usually determined by the standard single point positioning observation equation.
