Key Technical Benefits:

1. Strong Signal and High-quality Data: Complete Constellation, Full Frequency and 1480 Channels

The G40 features the innovative UM980 GNSS chip, which includes 1408 channels and supports a broad range of satellite signals, such as Tri-band GPS (L1/L2/L5), BDS (B1I/B2I/B3I/B1C/B2a/B2b), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b/E6), QZSS (L1/L2/L5), NavIC (L5), and SBAS.

The performance of this chip is significantly improved by using 5 constellations and 21 frequencies at the same time. This approach allows for more real-time data, leading to more stable and accurate positioning. 

Additionally, it offers faster RTK initialization, better anti-jamming capabilities, improved measurement accuracy, and greater reliability, particularly in challenging environments like urban areas or regions with dense tree cover.


2. IMU (Inertial Measurement Unit) Tilt Compensation: Calibration-Free and Ready to Use Without Initialization

Calibration and initialization FREE; Ready for tilt survey straight out of the box.

The GINTEC G40 RTK, equipped with a highly accurate Inertial Measurement Unit (IMU) and an innovative tilt compensation function, revolutionizes RTK tilt measurement by making it both practical and precise. This advanced device requires no calibration and is ready for precise measurements immediately upon activation, ensuring instant usability. Its resistance to magnetic interference makes it suitable for operation in any location, enhancing its versatility. Furthermore, the G40 RTK is not constrained by the traditional limitations of bubble leveling, leading to an efficiency improvement of at least 30% and ensuring greater measurement accuracy. This combination of features positions the G40 RTK as a highly reliable and efficient tool for various surveying needs.

3. G-FIX Technology: Maintaining Continuous Precision During RTK Data Interruptions

When RTK/RTCM correction data is lost or interrupted for any reason, G-FIX Technology effectively mitigates this loss or disruption for up to 10 minutes. This significantly reduces RTK downtime and enhances accuracy stability. 

4. AR (Augmented Reality) Visual Stakeout

The G40 AR GNSS receiver incorporates revolutionary vision technology that transforms the way surveyors work by overlaying digital information onto the real world. This cutting-edge tool assists surveyors in visualizing the stakeout location and designed features in real-time. It utilizes a professional-grade camera, ensuring clear visibility even under challenging lighting conditions, and a fusion algorithm that combines satellite and inertial navigation with visual perception.

This technology allows the surveyor to accurately locate the position of a design feature or structure on a site using a GNSS receiver. Subsequently, an augmented reality image of the feature is overlaid onto the real-world view, enabling precise staking out of the location in accordance with design specifications. 

The G40's innovative approach eliminates the need for repetitive pole adjustments and bypasses outdated compass-based systems, ensuring unparalleled accuracy without magnetic interference. Experience the future of surveying with the G40's real-time visual layout capabilities.
