{"title":"GPS + BDS BeiDou Dual Module","handle":"gps-bds-beidou-dual-module","url":"/products/gps-bds-beidou-dual-module","description":"A compact multi-constellation GNSS positioning module based on the AT6558 chip with 32 tracking channels. It simultaneously receives signals from six satellite navigation systems: GPS, BeiDou, GLONASS, Galileo, QZSS, and SBAS (WAAS, EGNOS, GAGAN, MSAS) for accurate joint positioning.\n\nThe module outputs via serial UART and is compatible with Arduino, Raspberry Pi, STM32, and other microcontroller platforms. An onboard rechargeable battery speeds up hot-start acquisition, and an E2PROM stores configuration settings between power cycles.\n\nKey Features\n\n\n6-System GNSS – GPS, BeiDou, GLONASS, Galileo, QZSS, and SBAS\n\n32 Tracking Channels – AT6558 multi-mode satellite chip\n\nDual Antenna Ports – SMA and IPEX connectors\n\nOnboard Rechargeable Battery – XH414 for fast hot-start acquisition\n\nE2PROM – Stores configuration settings\n\nAntenna Protection – Built-in detection and short circuit protection\n\nA-GNSS Support – Assisted GNSS for faster fixes\n\n\nSpecifications\n\n\nOperating Voltage – 3.3–5V\n\nCurrent Draw – <25mA (continuous operation)\n\nPositioning Accuracy – 2.5m CEP50 (open field)\n\nCold Start TTFF – ~32 seconds\n\nCold Start Sensitivity – -148dBm\n\nTracking Sensitivity – -162dBm\n\nInterface – Serial UART\n\nDimensions – 13.1 × 15.7mm\n\n\nIdeal For\n\nDrone and autonomous vehicle navigation\nVehicle tracking and fleet management\nHandheld GPS devices\nWearable positioning devices\n\n\nPackage Contents\n\n1× GPS + BDS BeiDou dual module\n1× Connector\n1× Pin header\n\n\nResources\n\nDFRobot Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2611,"title":"Default Title","sku":"DF-TEL0132","price":29.02,"on_sale":false,"in_stock":true,"available_quantity":99,"option1":"Default Title"}]}
