Features of GNSS
The systematically introduces the core performance features of GNSS
High Precision Positioning
Advanced GNSS technology supports multi-constellation satellite tracking, delivering centimeter-level RTK positioning accuracy even in challenging environments.
Fast RTK Initialization
The receiver achieves rapid initialization within seconds, ensuring efficient fieldwork and minimal waiting time for surveyors.
Rugged Industrial Design
Built for harsh outdoor environments with durable housing and industrial-grade protection.
All-Day Battery Performance
High-capacity batteries combined with intelligent power management ensure long working hours in the field.
How does it work?
Principle of the GNSS
GNSS RTK (Real-Time Kinematic) positioning uses satellite signals combined with differential correction data from a base station to achieve centimeter-level positioning accuracy.
Extension
Verlängerungsstange
Extension poles provide additional height and flexible mounting options for GNSS receivers, helping surveyors achieve stable and accurate positioning in various field conditions.
protecting
GNSS Surveying Umbrella
Designed to protect GNSS receivers and surveying instruments from direct sunlight and rain, ensuring stable performance and reliable positioning accuracy in outdoor environments.
Common Questions & Professional Answers
This is primarily caused by the Multipath Effect, where satellite signals are reflected off surfaces like buildings or leaves before reaching the antenna.
Mount Laser products utilize Advanced Error Elimination Algorithms to filter out reflected signals and prioritize direct line-of-sight data.
For extreme obstructions, use the Flex 42's Dual Camera AR feature. You can measure points remotely from an open area using visual positioning, eliminating the need to physically stand under the canopy.
Standard built-in radios typically operate at 1W-2W, which limits the working range. The R5 features a high-power 5W internal radio combined with an Up Side UHF Antenna Design.
| Feature | Standard Radio (1-2W) | R5 Built-in Radio (5W) |
|---|---|---|
| Signal Penetration | Weak in dense terrain | Strong / Robust |
| Working Range | Short to Medium | Long Range |
| Antenna Efficiency | Standard bottom mount | Optimized Top Mount |
This setup ensures a stable connection between the Base and Rover even in challenging environments, reducing the need for frequent base relocations.
In GNSS positioning, all satellites are above the horizon. This geometric limitation (DOP) means vertical accuracy is typically 1.5 to 2 times worse than horizontal accuracy.
To ensure the best vertical results:
- 1Perform a Site Calibration (Local Transformation) before starting.
- 2Ensure sufficient observation time to average out satellite geometry changes.
- 3Verify your height on known control points periodically.
The laser measurement is designed for "unreachable points" where a physical pole cannot be placed safely or accurately.
• Bottom of deep trenches or pits
• Points behind fences or walls
• Center of busy roads or dangerous edges
• High-up architectural features
Combined with AR Visual Guidance, surveyors can simply aim at the target from a safe distance and achieve centimeter-level non-contact measurement.
