M328 GNSS Receiver
M328 is independently developed by sunnavand adopts H328 board card. M328 adopts dual antenna reception, which can bewidely used in navigation and orientation field. It supports l-band function and has inertial navigation function. It is based on its light and strong body, efficient positioning data transmission fre-quency, stable positioning effect and convenient configuration method. It is widely used in agriculture, industry, water conservancy, ocean, surveying and mapping, aviation, transportation, municipal engineering and other fields.

Features

■ Extremely accurate heading with long baselines
■ Multi-frequency position, dualfrequency heading supporting GPS,GLONASS, BeiDou, Galileo, QZSS, IRNSS, and L-band
■ Atlas® L-band capable to 8 cm 95%
■ Fast RTK acquisition and reacquisition times
■ Excellent coasting performance
■ 5 cm RMS RTK-enabled heave accuracy
■ Strong multipath mitigation and interference rejection
■ New multi-axis gyro and tilt sensor for reliable coverageduring short GNSS outages
