Stonex S900+ GNSS Receiver

Stonex S900+ GNSS Receiver

The Stonex S900+ is a high-precision GNSS receiver designed for professional land surveying, mapping, and geospatial applications. It integrates a powerful multi-constellation GNSS engine with modern communication technologies to deliver reliable, accurate positioning in real-time and post-processing workflows. Its robust, weatherproof design and long battery life make it suitable for demanding field environments.

Key Features of Stonex S900+ GNSS Receiver

• Multi-Constellation GNSS Tracking
  Equipped with a 1408-channel GNSS board supporting GPS, GLONASS, BeiDou, Galileo, QZSS, and SBAS signals for enhanced satellite availability and positional accuracy.

• High-Performance Positioning
  Achieves centimeter-level precision with static and RTK survey modes. For baseline lengths under 30 km, RTK precision is typically 5 mm + 0.5 ppm horizontal and 10 mm + 0.5 ppm vertical.

• Optional IMU Tilt Compensation
  IMU (inertial measurement unit) technology enables fast initialization and tilt measurement up to 60°, reducing the need to level the pole precisely.

• Integrated 4G Modem
  Built-in 4G modem provides fast Internet connectivity for receiving correction data and supporting network RTK workflows worldwide.

• Smart Power System
  Dual hot-swappable smart batteries deliver up to 12 hours of continuous operation, with power status visible via LED or connected controller.

• Wireless Connectivity
  Includes Bluetooth and Wi-Fi modules for reliable data transfer between the receiver and controller.

• Integrated UHF Radio (Optional)
  Supports internal UHF TX/RX (e.g., 410–470 MHz) to enable Base-Rover communication without external radios; range up to 10 km under optimal conditions.

• Rugged Field Design
  IP67-rated enclosure provides dust and water resistance, making the receiver suitable for all weather conditions.
