What are the basic features of GPS module at vehicle gauge level

　　From outdoor to indoor, there are more and more location-based services, and more and more positioning technologies are gradually entering the mass market from the niche market. The market position of GNSS positioning module, as the representative of outdoor positioning and navigation, can never be shaken. After all, almost all vehicle navigation can not be separated from satellite positioning. Next, SKYLAB will analyze the characteristics of the GPS module of vehicle specification level for you.

　　1. Vehicle gauge level standard

　　First, high performance processors are required; HD audio and video hardware decoding; Fully compatible with original vehicle CAN bus protocol and original vehicle harness; Fast positioning and precise navigation; EMC electromagnetic compatibility performance shall reach the standard; Strict vehicle specification level design and test standards; Rest assured after-sales service. The vehicle gauge level is actually a set of hardware specifications. Those meeting the above standards can be called vehicle gauge class.

　　SKG12Q uses GNSS chips that meet AEC-Q100 standards, and the production process meets ISO/IATF16949 certification requirements. The quality test of the module complies with the relevant provisions of "Road Vehicles - Environmental Conditions and Electrical and Electronic Equipment Test Standards" in ISO16750 standard;

　　2. High sensitivity and positioning accuracy

　　The number of GPS receiving channels is 99, the receiving sensitivity is up to - 165db, the cold start time is 23s, the hot start time is less than 1s, and the warm start time is 2~3s, which truly achieves fast response. SKG12Q has high sensitivity and reliability, and internal flash memory can be upgraded to support applications in different scenarios;

　　3. Support multi system joint positioning and single system independent positioning

　　Support GPS, BDS, GLONASS, GALIEO, QZSS and SBAS, and support multi system joint positioning and single system independent positioning;

　　4. Ultra low power consumption

　　From the product specification of SKYLAB vehicle gauge level GPS module SKG12Q, the power consumption value is 30mA @ 3.3V Typical, 35mA @ 3.3V;

　　5. Fast positioning in weak signal environment

　　Additional pre LNA is used to optimize RF performance, and pre SAW filter can improve anti-interference performance, even in weak signals, it still has high positioning accuracy and short positioning time;

　　6. Small size, easy integration

　　The GPS module is an integrated circuit composed of RF radio frequency chip, baseband chip and core CPU, and related peripheral circuits. In order to better integrate into the PCB board of the customer's product, SKYLAB vehicle gauge level GPS module SKG12Q was designed to be 16 * 12.2 * 2.4 (mm) in the early design, which is compact and easy to integrate.
