This Mini GPS is an M5Stack unit that integrates an AT6558 navigation chip and a MAX2659 amplification chip which is used for amplifying the antenna signal. The AT6558 is a high performance chip that supports many types of satellite navigation systems, able to receive satellite signals on 56 channels GNSS signal from 6 satellite navigation system, joint location, navigation, timing and more. The module is able to obtain accurate global location information, quick and accurate positioning for anywhere in the city, in the canyon, under the overhead and inside the car. You can plug it into port C on M5core via GROVE cable, which is a standard UART interface. UART settings: * Baudrate: (default: 9600bps) * Start bits: (1 bit) * Stop bits: (1 bit) * Parity: (no) Features * Support single system positioning of BDS/GPS/GLONASS satellite navigation systems, or multi-system joint positioning in any combination * Support D-GNSS differential positioning * Two Lego-compatible holes Package Contents * 1x GPS Unit * 1x Grove Cable Specifications Resources Parameter Positioning accuracy 2.5m Channel 56 Positioning update frequency 1-10Hz Maximum height 1800m Maximum speed 515m/s Maximum acceleration <= 4g Sensitivity Tracking: -162dBm,Capture: -148dBm,Cold start: -146dBm Start Time Cold start: 35 seconds,Warm start: 32 seconds,Hot start: 1 second Operating temperature -40°C - 85°C Net weight 13g Gross weight 26g Product Size 48 x 24 x 8mm Package Size 67 x 53 x 12mm Resources * Documents https://elecena.pl/product/22723907/m5stack-mini-gps-bds-unit-at6558-discontinued 2023-03-07 https://elecena.pl/product/22723907/m5stack-mini-gps-bds-unit-at6558-discontinued 2023-12-27 https://elecena.pl/product/22723907/m5stack-mini-gps-bds-unit-at6558-discontinued 2024-09-19 https://elecena.pl/product/22723907/m5stack-mini-gps-bds-unit-at6558-discontinued 2024-11-29 https://elecena.pl/product/22723907/m5stack-mini-gps-bds-unit-at6558-discontinued 2024-11-30
