Description Unit-GPS SMA is a GNSS global positioning and navigation unit, integrating the high-performance ATGM336H navigation module from Microelectronics, based on the AT6668 chip design. It is equipped with an external active antenna, offering more precise and reliable satellite positioning services. Compared to previous models, the AT6668 supports multi-frequency and multi-mode GNSS signal reception, enabling compatibility with multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS). It supports combined multi-system positioning or single-system independent positioning, offering enhanced interference resistance and higher positioning accuracy. This module is well-suited for high-accuracy positioning applications such as vehicle navigation, IoT location devices, and more, even in weak signal areas. Product Features Supports multiple satellite navigation systems (GPS/QZSS/BD2/BD3/GAL/GLO) Multi-frequency and multi-system reception Multi-channel support External active antenna 2x LEGO-compatible holes Programmable platforms: Arduino, UIFlow, ESP-IDF, etc. Includes 1x Unit-GPS SMA 1x HY2.0-4P cable (20CM) 1x External active antenna Applications Vehicle positioning and navigation Wearable devices IoT location devices Drones Portable devices Public transportation announcement systems Specifications Specification Details SoC AT6668 Supported Systems GPS/QZSS/BD2/BD3/GAL/GLOFrequencies:BDS: B1I+B1C GPS/QZSS/SBAS: L1 GALILEO: E1 GLONASS: R1 Channels 50 Communication UART (default: 115200bps@8N1) Positioning Accuracy <1.5m (CEP50) Positioning Update Maximum 10Hz Protocol NMEA0183 4.1 Sensitivity Tracking: -162dBm, Acquisition: -160dBm, Cold start: -148dBm Startup Time Cold start: 23 seconds, Hot start: 1 second Antenna SMA active external antenna (inner thread, inner pin), Gain: 30DBI Frequency: 1555MHz~1580MHz Length: 1m Size: 38*36*13mm Power Consumption Standby: DC5V/31.64mA Working: DC5V/40.90mA Product Dimensions 71.4*24*8mm Packaging Dimensions 136*92*13mm Product Weight 11.2g Packaging Weight 59.6g LEARN AND DOCUMENTS DOCUMENTS
