Overview

QU232U7 is an external GPS receiver, the protocol is NMEA 0183, the default baud rate is 4800. Supports GPS/WAAS+QZSS+SBAS, supports up to 56 satellite tracking channels, and with satellite-based enhanced satellites, the horizontal positioning accuracy can reach 2 meters. ​QU232U7 also supports SBAS (Satellite-Based Augmentation System) which is the generic name given to the differential signal transmitted by various local geo-stationary satellites. SBAS allows GPS receiver to remove errors in the position due to environmental conditions and improves accuracy down to <2m. Using WAAS in the US and EGNOS in Europe the QU232U7 will automatically switch to differential SBAS mode when available. ​This product is compatible with Garmin, raymrine and other GPS sensors. Please make sure your device has an NMEA 0183 interface and operates at 4800 baud before purchasing. ​Users can also personalize the GPS receiver configuration via PC software:U-center to meet the needs of different devices. Including baud rate, NMEA messages, protocol, navigation rate, PPS LED status, etc. ​ ​Factory configuration: ​Baud rate: 4800 bps ​NMEA messages: GGA RMC GLL VTG GSV GSA ZDA ​ ​If you need to change the configuration, please inform the customer or leave a message before placing an order.

Please note that do not connect the GPS signal wires (TX RX) to the positive pole of your power supply, otherwise it will immediately damage the antenna. ​If you don't know how to connect wires, please provide the NMEA 0183 interface description of your device to customer service and request assistance.

In the default configuration, the NMEA-GSV GSA ZDA messages are sent at 4-second intervals to avoid overflow in the TX buffer.
