One of the main requirements coming from different clients is to add an "anti-theft alarm" function to our gps trackers, which will trigger the loud BEEP BEEP alarm whenever the motorcyc...
High precision GPS measurement must use carrier phase observation values. RTK positioning technology is a real-time dynamic positioning technology based on carrier phase observation values, which ...
(1) Support standard and accurate positioning algorithms: GPS, GLONASS, QZSS Quasi-Zenith Satellite System, Beidou and SBAS. (2) Supports multiple positioning modes and GNSS real-time and post pr...
The biggest problem encountered in the application of RTK technology is the effective range of reference station calibration data. The spatial correlation of GPS errors gradually loses linearity a...
The benchmark station subsystem is the data source of the network RTK system, and the stability and reliability of this subsystem will directly affect the performance of the system. The functions ...
GPS antennas can be divided into vertical polarization and circular polarization in terms of polarization mode. The effect of vertical polarization is not as good as that of circular polarization...
1. Ceramic flakes: The quality of ceramic powder and sintering process directly affect its performance. The main ceramic chips currently used on the market are 25 25, 18 18. 15 15. 12 12. The ...
The main manufacturers that can independently produce GPS ceramic antennas are Da Gama Navigation, Jiaxing Jiali Electronics, Jiabang, Jiakang Electronics, and other manufacturers. Most manufactu...
1. GPS cannot locate 100%, let alone believe the nonsense of indoor positioning. Unlike mobile phone broadcasting, GPS can receive signals everywhere, and many things will affect GPS reception, in...
Car locator, also known as car positioning tracker, is mainly a vehicle anti-theft GPS positioning product. The functions of car positioning trackers generally include SMS positioning, timed posit...
