Geosun GS 1500N 1500m Long Range UAV LiDAR Scanner

The GeoSun GS-1500N is a professional long-range LiDAR mapping system for UAV, VTOL and vehicle-based surveying. It integrates a long-range laser scanner, multi-constellation GNSS, an inertial navigation system, data storage and optional camera imagery to produce accurately georeferenced 3D point clouds.

Typical applications include topographic surveying, power-line and utility corridor mapping, forestry, agriculture, land planning, infrastructure inspection, digital-city mapping and other projects that require detailed 3D spatial information over relatively large areas.

Yes. UAV LiDAR surveying is one of the primary applications of the GS-1500N. Its integrated LiDAR, GNSS and INS components allow a compatible drone or VTOL platform to collect point-cloud data while the system records the position and orientation required for georeferencing.

Yes. The GS-1500N is suitable for compatible multi-rotor and VTOL platforms. Its long measurement range makes it particularly useful for VTOL projects where larger areas need to be surveyed efficiently from higher flight altitudes.

Yes. GeoSun describes the GS-1500N as a UAV and vehicle measurement system. When installed and calibrated correctly, the integrated LiDAR and positioning system can be used for compatible mobile-mapping applications from a moving ground vehicle.

The GS-1500N is designed for professional survey companies, geospatial service providers, engineering firms, power-line inspection teams, forestry specialists, UAV mapping operators and other organisations that need long-range, high-density LiDAR data.

GeoSun specifies a maximum ranging capability of up to approximately 1,500 metres for the GS-1500N under suitable conditions. Current manufacturer specifications also reference approximately 1,000 metres on an 80% reflective target. Actual usable range depends on target reflectivity, weather, atmospheric conditions, scan angle and project requirements.

GeoSun specifies overall system accuracy of approximately 10 cm at a 400 m survey distance under suitable conditions. The laser scanner itself has a specified ranging accuracy of approximately 5 mm at 100 m. Final point-cloud accuracy also depends on GNSS conditions, INS performance, calibration, flight geometry and processing.

The approximately 5 mm specification describes the laser scanner's distance-measurement accuracy at 100 m. The approximately 10 cm at 400 m figure describes the complete georeferenced mapping system. Final coordinates are affected by laser ranging as well as GNSS position, platform attitude, mounting calibration and survey distance.

Current GeoSun specifications list a measurement rate of up to approximately 1.5 million points per second. A high point rate helps maintain useful point-cloud density when surveying from greater heights or when the UAV is travelling relatively quickly.

The GS-1500N laser scanner provides a field of view of approximately 100°. This allows the system to cover a wide swath beneath the aircraft during airborne mapping missions.

Yes. The GS-1500N supports multiple laser returns. The standard product documentation lists five echoes, while current manufacturer configurations can support additional returns depending on the scanner configuration. Multiple returns are particularly useful in vegetation because a pulse can record information from the canopy as well as surfaces beneath it.

GeoSun's reference mission data lists approximately 135 points/m² at a 200 m flight height and approximately 40 points/m² at 400 m when flying at about 10 m/s. Actual point density depends on flight altitude, speed, scan settings, overlap and terrain.

Yes. The GS-1500N integrates multi-frequency GNSS with an inertial navigation system. Together they continuously record the position, heading, pitch and roll of the LiDAR platform so individual laser measurements can be transformed into georeferenced 3D coordinates.

The integrated positioning system supports GPS, GLONASS, BeiDou and Galileo. Supported signals include GPS L1/L2/L5, GLONASS L1/L2, BeiDou B1/B2/B3 and Galileo E1/E5a/E5b.

The integrated positioning and orientation system is specified with position accuracy of up to approximately 0.05 m, pitch and roll accuracy of approximately 0.003° and heading accuracy of approximately 0.010°. The trajectory solution operates at an update frequency of up to 200 Hz.

A full-frame camera is available as part of the GS-1500N configuration. GeoSun documentation specifies a 45 MP camera with a 40 mm focal length and field-of-view options of approximately 57° or 79°. Camera imagery can be combined with LiDAR data to produce colourised point clouds and additional mapping products.

GeoSun provides Shuttle software for processing the GNSS/INS trajectory and gAirHawk software for LiDAR point-cloud processing. The processed trajectory and laser measurements are combined to generate georeferenced point-cloud data for further surveying, GIS or engineering analysis.

Yes. The GeoSun workflow can produce standard point-cloud data for use in compatible surveying, CAD, GIS and point-cloud processing software. LAS is commonly used for exchanging georeferenced LiDAR point clouds between different applications.

GeoSun's reference data lists approximately 2.8 km² of coverage at a 200 m flight height and approximately 5.6 km² at 400 m under the stated test conditions. Actual coverage depends on the aircraft, flight endurance, altitude, speed, overlap, terrain, regulations and required point density.

The GS-1500N weighs approximately 2.5 kg. When selecting an aircraft, the payload calculation should also account for the mounting system and any other equipment required for the complete installation.

The GS-1500N measures approximately 238 × 102 × 130 mm. Its integrated design combines the LiDAR scanner, GNSS/INS and recording hardware into a compact payload for professional UAV and mobile-mapping applications.

The GS-1500N product documentation specifies a 512 GB solid-state drive with support for an additional 128 GB TF card. Required storage capacity depends on mission duration, LiDAR measurement rate and whether camera imagery is being recorded.

The specified operating temperature range is approximately -20°C to +55°C. The complete mapping platform must also remain within the environmental limits of the UAV, batteries, GNSS equipment, camera and other components used during the survey.

Yes. Forestry and electrical-infrastructure surveying are important applications of the GS-1500N. Its long range, high measurement rate and multiple-return capability can help capture vegetation structure, terrain beneath vegetation and detailed information along transmission corridors and substations.
