Baidu map is one of the mainstream navigation software in China at present, and its Beidou navigation system is also the first internet map software in China that can provide positioning and navigation for all users in the country.

Baidu map Beidou positioning open platform was upgraded from Baidu map intelligent positioning open service. Baidu map intelligent positioning open service has been upgraded to Baidu map Beidou positioning open platform, and many functions such as lane-level navigation and parking-level navigation have been comprehensively upgraded.

In September 2022, Baidu map intelligent positioning open service was officially upgraded to Baidu map Beidou positioning open platform. With the blessing of Beidou satellite navigation system, it will provide a full-link one-stop solution for many fields such as automobile, finance, logistics and tourism, and empower more than 2.55 million developers with safer, more accurate and more stable services.

Characteristics of Baidu map Beidou positioning open platform;

Feature 1: Switch Beidou positioning first. Baidu Beidou single-mode positioning is the first positioning service for high security and high confidentiality industries. Developers can choose to give priority to Beidou's single-mode positioning capability to provide users with safer services. The financial industry and state institutions have a strong demand for giving priority to Beidou positioning.

Feature 2: indoor high-precision positioning. Using triangulation technology, enhanced WiFi fingerprint model technology, geomagnetism technology, Bluetooth and other technologies, the industry-leading positioning performance is achieved, covering thousands of indoor places in China.

Feature three, global positioning. Baidu has built its own global positioning service capability to help developers develop global business and fully realize the integration of domestic and foreign services. Support more than 200 countries around the world.

Feature 4: Intelligent hardware positioning. Using WiFi and base station information, accurate positioning function can be realized, which meets the requirements of intelligent hardware positioning, covering security, medical care, sports, vehicle equipment, smart home, Internet of Things, aircraft and other industries.

Feature 5: Intelligent inertial navigation and positioning. In the face of weak signal scenes such as satellite missing, tunnel and overhead, Baidu Map provides intelligent inertial navigation based on high-precision inertial navigation and a new intelligent positioning engine of position big data to realize continuous navigation.

Feature 6: Positioning to prevent cheating. In view of the fact that the virtual positioning software in the market can tamper with the user's position, this paper explores the influence characteristics of various simulation positioning methods on the internal information of Baidu positioning SDK, integrates multi-source data information, and effectively recognizes the location authenticity of simulated satellite positioning results, that is, check-in, sports, travel, games and other scenes.
