How We Ensure Accuracy in Land Surveying

Accurate positioning is the foundation of modern surveying, mapping, construction and infrastructure projects. However, traditional surveying methods can be affected by difficult terrain, complex environments, time-consuming setup procedures and limited communication coverage. Our GNSS RTK solutions combine high-precision positioning, advanced satellite tracking, RTK correction transmission, laser ranging, tilt compensation and AR-assisted stakeout to help surveyors work faster and with greater confidence.

From establishing RTK base stations to collecting field coordinates and completing construction stakeout, our GPS/GNSS receiver solutions provide reliable positioning support for a wide range of professional surveying applications.

Industry Challenges in Surveying & Mapping

1. Time-Consuming Equipment Setup

External batteries, radios and cables make traditional RTK systems complex and time-consuming to set up.


2. Unstable Positioning in Difficult Environments

Trees, buildings and reflective surfaces can interfere with satellite signals and reduce positioning stability.


3. Limited RTK Correction Coverage

Traditional radio systems may provide limited correction coverage across large or obstructed surveying areas.


4. Difficult Stakeout Operations

Manual point locating and repeated measurements can slow down construction and infrastructure stakeout operations.

How Our GNSS RTK Solutions Solve These Challenges
  • All-in-One GNSS RTK Base Station for Faster Deployment

    The M2 GNSS SYSTEM integrates the key components required for RTK correction transmission into one compact GNSS RTK station. Its integrated design eliminates the need for multiple external cables and batteries, simplifying field deployment.
    With a built-in 4G modem, the M2 can transmit GNSS corrections through TCP/IP services, while its UHF modem provides reliable correction transmission for conventional RTK surveying workflows. This all-in-one architecture can significantly reduce setup complexity and help surveying teams start projects faster.

    Recommended for:
    Land surveying, topographic surveying, construction surveying, infrastructure projects, large-area mapping and RTK base station applications.
  • Reliable GNSS Tracking for Challenging Surveying Environments

    The M2 GNSS SYSTEM uses a 1408-channel GNSS platform supporting GPS, GLONASS, Galileo and BeiDou. Advanced GNSS antenna technology and multipath mitigation algorithms improve satellite signal tracking and help maintain reliable positioning performance in environments affected by signal reflections and obstructions. The combination of multiple satellite constellations and advanced signal processing allows the GNSS receiver to obtain more positioning information from available satellite signals.

    Recommended for:
    Urban surveying, suburban mapping, construction sites, infrastructure corridors, wooded areas and other environments where satellite signal conditions can vary.
  • Long-Range RTK Correction Transmission

    For projects requiring reliable communication between the base station and rover, the M2 provides UHF correction transmission with coverage of up to 8 km under typical surveying conditions and up to 5 km in difficult environments such as wooded and suburban areas. Its optimized power consumption and high-capacity battery support extended field operation, with up to 15 hours of continuous operation when transmitting RTK corrections at 5 W output power.

    Recommended for:
    Large construction sites, land development, road and infrastructure surveying, agricultural mapping and large-area topographic surveys. GNSS RTK Solutions for Fast and Accurate Field Stakeout
  • Laser Ranging for Remote Target Measurement

    The N1 GNSS SYSTEM combines high-precision GNSS positioning with an integrated laser ranging function. It can capture the coordinates and distances of targets up to 25 meters away, reducing the need to physically reach every measurement point. This is particularly useful when the target is located behind obstacles, in difficult terrain or in an area that is inconvenient to access directly.

    Recommended for:
    Topographic surveying, construction surveying, building surveys, road surveys and hard-to-access target measurement.
