High-Precision RTK GNSS Handheld Device for Surveying and Mapping

Introduction to High-Precision GNSS Handheld Devices

High-precision positioning technology plays an important role in modern surveying, mapping, agriculture, forestry management and infrastructure inspection. GNSS handheld devices equipped with RTK technology allow professionals to obtain accurate positioning data directly in the field.

The XM320R high-precision RTK GNSS handheld device is designed for reliable data collection and measurement in complex outdoor environments.

Multi-Constellation GNSS Positioning

The XM320R supports multiple global satellite navigation systems including:

• Beidou (BDS)
  
• GPS
  
• Galileo
  
• QZSS
  

By combining signals from multiple satellite systems, the device provides stable positioning performance even in environments with limited satellite visibility such as forests, mountains or urban areas.

Centimeter-Level RTK Positioning Accuracy

The device integrates advanced RTK (Real-Time Kinematic) technology to achieve high-precision positioning.

Positioning performance includes:

• Single point accuracy: 3-5 meters
  
• RTK positioning accuracy: up to 2.5 cm + 1 ppm
  

This level of accuracy makes the XM320R suitable for professional surveying and mapping applications.

Built-in 4G Communication and CORS Support

XM320R supports 4G communication and can connect to CORS RTK correction services. With network correction data, users can obtain centimeter-level positioning without setting up a local base station.

This greatly improves operational efficiency for field surveyors.

Communication options include:

• 4G CAT1
  
• WiFi
  
• Bluetooth
  

Professional Measurement Functions

The handheld device provides multiple measurement and data collection functions including:

• Point measurement
  
• Area measurement
  
• Polygon area calculation
  
• Straight line distance measurement
  
• Curve length measurement
  
• Terrain elevation difference calculation
  

These functions are widely used in land surveying, agriculture measurement, forestry resource management and GIS data collection.

Flexible Coordinate System Support

XM320R supports multiple coordinate systems used worldwide, including:

• WGS84
  
• CGCS2000
  
• Beijing 54
  
• Xi’an 80
  
• UTM
  
• MGRS
  

Custom coordinate systems are also supported, making the device adaptable to different regional survey standards.

Reliable Design for Outdoor Field Operations

The XM320R handheld GNSS receiver is designed for outdoor environments.

Key hardware features include:

• 3.2-inch display screen
  
• 5000mAh battery with more than 12 hours working time
  
• IP65 protection level
  
• Operating temperature from −20°C to 70°C
  

The device is lightweight and portable, weighing only 271 grams.

Application Scenarios

The XM320R high-precision GNSS handheld device can be widely used in various industries:

• Land surveying
  
• Agriculture mapping
  
• Forestry management
  
• Pipeline inspection
  
• GIS data collection
  
• Infrastructure construction
  

Conclusion

With multi-constellation GNSS support, built-in RTK technology and reliable outdoor design, the XM320R handheld device provides a practical solution for professionals who require accurate positioning and efficient field data collection.

It is an ideal tool for surveying, mapping and geospatial applications.
