Beidou /GPS vehicle monitoring terminal receives the positioning signals of Beidou-2 satellite and GPS satellite, and carries out two-way short message and data communication with monitoring center through GPRS/CDMA network channel in combination with vehicle status information. Vehicle-mounted terminals regularly upload real-time information such as vehicle position, motion state and alarm situation to the monitoring center, and the monitoring center releases road condition information and early warning information to the vehicle-mounted terminals as needed through GPRS/CDMA network to dispatch, monitor and manage the vehicles in real time.
Navigation and positioning is the primary function of vehicle monitoring terminal, and Beidou /GPS navigation module is the core component of monitoring terminal. He Xinxing Tong UM220 series modules have excellent navigation and positioning performance. Through the mixed application of correlator, FFT and matched filter and algorithm optimization, the module can quickly locate for the first time in various complex environments and maintain stable acquisition and tracking ability. Advanced multipath suppression technology effectively ensures the accuracy and reliability of navigation and positioning.
He Xinxing Tong realized the first 10,000-level application in Beidou industry on 201/,and quickly extended it to a number of terminal integration manufacturers to realize batch application.
Portable navigation and positioning
Portable navigation and positioning products provide users with more convenient location services, such as PND, walkie-talkie, cluster applications, etc. , allowing users to obtain location information anytime, anywhere.
He Xinxing realized the combined positioning of Beidou system and GPS through Beidou /GPS portable navigator. At the same time, it has the functions of audio, video, FM transmission, WIFI wireless Internet access, intelligent touch screen, voice navigation support and various map software. Compared with a single GPS PND product, this product has higher positioning accuracy and usability, and can be widely used in the field of vehicle navigation.
The introduction of this product has broken the monopoly position of GPS system in China portable navigation equipment market, and strongly promoted the development of Beidou navigation industry in civil and industrial applications.
Location information is the basic information of cluster application. The combination of location service, voice communication and data transmission provides technical support for mass applications such as industry scheduling, trunking communication and field exploration.
The walkie-talkie integrated with Beidou /GPS dual-mode chip/module is compact and has strong endurance, which can be widely used in professional wireless communication fields such as public security, airports, ports and subways. It is also suitable for personal outdoor activities, outdoor adventures and other directions.
Accurate timing
Among the three standards in the field of mobile communication, CDMA2000 and TD-SCDMA are both base station synchronization systems. The switching of base station work, roaming and other business processing all need accurate time control, otherwise it will bring serious system interference. The existing common solution is to configure GPS satellite timing on each base station equipment. Relying entirely on Beidou /GPS system has potential safety hazards, and adopting Beidou satellite timing system independently developed by China will avoid this problem.
He Xinxing's advanced multipath suppression technology and high-quality original observation data ensure the accuracy of positioning and timing. The scheme supports Beidou /GPS single system timing and dual system timing, and the timing accuracy is better than 20ns, and it can be switched freely between satellite systems.
ocean fishery
Fishery ship position monitoring system is the largest civil promotion project of Beidou system at present, and it is also the key implementation project of the Ministry of Agriculture to implement the scientific development of agriculture (fishery). The fishing position monitoring system has built a Beidou satellite integrated information service network integrating sea, land and land. On the one hand, the system can provide fishing boat position monitoring, fishing boat emergency rescue command, fishery policy release, typhoon passage at sea and other services for fishery management departments. On the other hand, it can also provide autonomous navigation, distress and point-to-point communication services for offshore fishery producers and operators. Marine fishery ship position monitoring system is mainly composed of three subsystems, including network operation service subsystem, ground monitoring station subsystem and ship-borne terminal subsystem.
Based on the solution of He Xinxing Tong UM220, Beidou /GPS compatible positioning can be realized. Due to the products developed based on its own chips, UM220 products have unique advantages in consistency, stability and cost. The ship-borne fishery terminal equipment developed by this module can ensure the safety monitoring and timely information communication of fishing boats; At the same time, the integrated module can achieve the goals of miniaturization, high performance, low power consumption and low cost, and greatly improve the application performance and market competitiveness of the ship-borne fishery terminal.
Meteorological application
In the meteorological field, we can use the Beidou high-precision measuring receiver laid on the ground to observe the delay caused by the Beidou satellite signal passing through the atmosphere to reach the ground for water vapor detection, or use the position and speed information output by the Beidou positioning module installed on the sounding balloon for high-altitude wind measurement. In recent years, observing the occultation of Beidou with LEO satellites and the airborne or ground-based Beidou reflection signal receiver have also become the research focus in the field of meteorological exploration.
