eRTK25
The eSurvey eRTK25 is a high-precision GNSS receiver that combines laser ranging with a dual wide-angle visual measurement system, designed to deliver accurate results even in demanding environments such as bright sunlight, confined spaces, or extreme temperatures.
High-precision visual GNSS receiver
The eRTK25 introduces a new class of visual GNSS receivers, integrating high-accuracy laser measurement and augmented reality with CAD drawings to achieve superior field productivity.
It is ideal for industrial, construction, and geospatial applications that require centimeter-level accuracy without physical contact.
Main features
- AR CAD Stakeout: overlays CAD drawings onto real-world environments using augmented reality, increasing field efficiency by up to 40%.
- Laser precision: non-contact measurements with centimeter-level accuracy (±1 cm + 5 mm/m) over a range of 0.1–50 m.
- 60° IMU: dynamic tilt compensation for fast and stable measurements.
- Dual 5 MP cameras: top and front wide-angle vision for enhanced coverage and measurement precision.
- Extreme durability: operating temperature range from -30 °C to +70 °C, IP67 rating, and 2 m drop resistance.
- Long-range UHF radio: up to 15 km communication and compatibility with major industry protocols (TrimTalk, Satel, South, Geotalk, etc.).
Visual + Laser Measurement
By combining laser and dual-vision technologies, the eRTK25 enables precise coordinate capture without physically reaching the point. This is essential in hazardous, inaccessible, or high-temperature environments.
AR CAD Stakeout – Augmented CAD-based layout
CAD designs are overlaid directly onto the real-world environment via the display or viewer, allowing a more intuitive and accurate stakeout process. The CAD AR Stakeout function shortens working time and minimizes errors, simplifying complex construction and engineering tasks.
Laser range with centimeter accuracy
The eRTK25 laser system provides non-contact centimeter-level measurements over an operational range of 0.1–50 m with an accuracy of ±1 cm + 5 mm/m. Ideal for confined spaces, walls, edges, or areas where direct contact is not possible.
Up to 60° tilt – No leveling required
The eRTK25 allows accurate measurements without leveling the pole, even with tilts up to 60°. Its integrated IMU ensures dynamic stability, maintaining accuracy even if the pole moves—as long as the tip remains steady.
Long-range UHF radio
With its integrated UHF modem of up to 2W, the eRTK25 provides communication over distances up to 15 km under optimal conditions. It is compatible with major international protocols, ensuring full interoperability with other base and rover systems.
GNSS compatibility and performance
With 1408 GNSS channels, the eRTK25 simultaneously processes signals from GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC, SBAS, and L-Band, ensuring stable and precise positioning worldwide, even in urban or obstructed environments.
