1. Small size, gold sinking process, excellent heat dissipation performance. The antenna performs t-type network impedance matching, the standing wave ratio is lower than 2.3, and the star search performance is strong. Excellent positioning and orientation function,high sensitivity, 1408 channels, support full-frequency point on-chip RTK positioning and dual-antenna orientation solution. 2. Dual interfaces:1.TYPE-C interfaces, and connect to a PC to view data. 2. XH2.54x6Pin interface for easy embedding of User System devices. 3. Dual antenna input, Dual-RTK dual RTK engine technology, differential input RTCM format adaptive recognition. supports 3 x UART, 1 x i2x*, 1 x SPI *, and 1 x CAN *. 4. Excellent positioning and orientation function, support BDS/GPS/GLONASS satellite full-system Full-frequency point on-chipRTK positioning and dual-antenna orientation calculation, and support QZSS and SBAS systems. Positioning accuracy: RTK positioning; horizontal 0.8cm + 1ppm, elevation 1.5cm + 1ppm. 5. Built-in antenna detection and antenna short circuit protection functions. The module is the general name of the series of high-performance BDS/GNSS full constellation high- precision positioning and orientation modules with the size of 26x38mm. The module products are all based on the design of a of RF baseband and high-precision algorithm integrated chip-GNSS SoC independently developed NebulasIV hexinxingtong. The main antenna and the secondary antenna simultaneously track the full-frequency points of the whole system including the Beidou three-sphere signal to realize on-chip RTK positioning and dual-antenna directional calculation. It has Dual-RTK dualRTK engine technology and differential input RTCM format adaptive recognition function.The built-in advanced anti- interference unit ensures that the module can still provide reli and accurate positioning accuracy even in complex electromagnetic environment. It is aimed at high-precision navigation and positioning fields such as unmanned aerial vehicles, autonomous machines,precision agriculture and intelligent driving. Application: 1. vehicle positioning and navigation 2. mobile phones,tablets,handheld devices 3. embedded positioning equipment 4. wearable devices 5. unmanned aerial vehicles,precision aqriculture, robots Due to different product batches,the appearance may be different,which does not affect use.
