Product Details
This is a compact positioning and navigation module powered by the AT6558, a top - notch multi - mode satellite navigation and positioning chip. It offers real - time location info and supports multiple satellite navigation systems with 32 tracking channels. The module can simultaneously receive GNSS signals from 6 major satellite navigation systems, including China's BDS, the US GPS, Russia's GLONASS, Europe's GALILEO, Japan's QZSS, and the SBAS satellite augmentation system. It enables joint positioning, navigation, and timing. In serial output mode, it's compatible with various mainboards like Arduino, Raspberry Pi, and STM32. With a positioning accuracy error of about 3m, similar to smartphones, and a low power consumption of just 0.1W, it can work continuously on a small power supply. Its small size makes it perfect for embedding in drones and smart cars. It's also great for vehicle navigation, handheld positioning, and wearable devices, and can replace the Ublox MAX series module. Specification: Operating Voltage: 3.3 - 5V; SMA and IPEX Antenna Ports; Onboard E2PROM for storing settings; Onboard XH414 rechargeable battery for faster hot - start; Supports A - GNSS; Cold - start Acquisition Sensitivity: - 148dBm; Tracking Sensitivity: - 162dBm; Positioning Accuracy: 2.5m(CEP50, open field); Time to First Fix: 32 seconds (varies by environment); Low Power: <25mA (continuous work); Built - in antenna detection and short - circuit protection; Dimension: 13.1 x 15.7mm/0.52 x 0.62”. Documents: Product wiki. Shipping List: GPS + BDS BeiDou Dual Module x1, Connector x1, Pin x1.
Using this module is quite easy. First, connect it to your compatible mainboard like Arduino or Raspberry Pi through the serial output. Make sure to connect the antenna to either the SMA or IPEX antenna port. Once connected, power it up with a voltage between 3.3V and 5V. It'll start searching for satellite signals and provide you with real - time location information. Regarding the time to first fix, it might take around 32 seconds or a few minutes depending on your environment. When it comes to maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures. The onboard rechargeable battery helps speed up the hot - start, but if you notice any issues with the battery, you may need to replace it. Also, the built - in antenna detection and short - circuit protection will safeguard the module from antenna - related problems, but still handle the antenna carefully.
