GPS/BDS Unit v1.1 (AT6668)
Description GPS Unit v1.1 is a GNSS global positioning navigation unit, integrating the high-performance CASIC navigation chip AT6668 and signal amplifier chip MAX2659, with a built-in ceramic antenna, providing more precise and reliable satellite positioning services. Compared to previous products, AT6668 supports multi-frequency and multi-mode GNSS signal reception, receiving signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS), supporting multi-system combined positioning as well as single-system standalone positioning. It has enhanced anti-interference capability and higher positioning accuracy, allowing it to quickly acquire high-precision location information in areas with weak signals. This module is widely applicable in high-precision positioning applications, such as in-vehicle positioning and navigation, IoT positioning devices, and more. Features Supports multiple satellite navigation systems (GPS/QZSS/BD2/BD3/GAL/GLO) Multi-frequency and multi-system reception Multi-channel Low power consumption 2x LEGO-compatible holes Programming platforms: Arduino, UIFlow, etc. Contents 1x Unit-GPS v1.1 1x HY2.0-4P Cable (20CM) Applications In-vehicle positioning and navigation Wearable devices IoT positioning devices Drones Portable devices Public transportation station reporting Specifications Specification Parameter SoC AT6668 Supported Systems GPS/QZSS/BD2/BD3/GAL/GLOFrequencies:BDS: B1I+B1CGPS/QZSS/SBAS: L1GALILEO: E1GLONASS: R1 Channels 50 channels Communication UART communication, default 115200bps@8N1 Positioning Accuracy <1.5m (CEP50) Update Rate Max 10Hz Protocol NMEA0183 4.1 Sensitivity Tracking: -162dBm, Acquisition: -160dBm, Cold Start: -148dBm Start Time Cold Start: 23 seconds, Hot Start: 1 second Power Consumption DC5V/31.64mA Product Size 48*24*8mm Package Size 136*92*9mm Product Weight 12.3g Package Weight 17.7g LEARN AND DOCUMENTS DOCUMENTS
