MS401 Monitoring GNSS Receiver
The Hi-Target MS401 GNSS Monitoring Receiver is a compact, IP68-rated, high-precision system designed for real-time geohazard, slope, mine, bridge, and reservoir monitoring. With 1408 channels, multi-constellation GNSS support, built-in MEMS sensor, intelligent communication (4G/NB-IoT/LoRa), and ultra-low ≤2.6W power consumption, it delivers reliable, stable, and continuous deformation monitoring in harsh field environments.
Description
The Hi-Target MS401 GNSS Monitoring Receiver is a powerful all-in-one deformation monitoring solution engineered for long-term, high-precision geotechnical and structural health monitoring. Built with a Linux-based operating system, integrated GNSS board, antenna, advanced MEMS sensors, and multi-network communication modules, the MS401 provides superior stability, low power consumption, and intelligent remote management.
Equipped with 1408 channels and support for GPS, GLONASS, BDS, Galileo, QZSS, and SBAS, the MS401 delivers precise and reliable positioning for critical applications such as landslide monitoring, slope stability analysis, dam safety, mining operations, bridge deformation tracking, and reservoir surveillance.
Its rugged IP68 protection rating, shockproof and drop-proof design, and operating temperature range of –40°C to 85°C ensure exceptional durability in extreme environments. The unit features a high-accuracy MEMS sensor with a 0.1° tilt accuracy and 1mg accelerometer precision, enabling dynamic monitoring frequency adjustments.
The MS401 supports multiple communication modes, including 4G, NB-IoT, LoRa (optional), Bluetooth, LAN, RS232, and RS485 connections. Intelligent communication switching, built-in firewall protection, self-diagnosis, self-healing, and remote configuration capabilities ensure secure, efficient, and continuous monitoring with minimal maintenance.
Designed for fast deployment, low power usage (≤2.6W), and seamless integration into monitoring networks, the Hi-Target MS401 delivers a highly reliable, smart, and professional-grade solution for modern geotechnical monitoring.
