Geosun GS 960 750m Long Range UAV LiDAR Mapping System

Long-range UAV LiDAR for professional aerial surveying

The Geosun GS-960 is a high-precision airborne LiDAR mapping system developed for surveyors, drone operators, civil engineers, utilities, forestry teams and geospatial professionals who need to collect accurate 3D data efficiently over large areas. The system integrates survey-grade LiDAR with GNSS positioning, a high-performance inertial measurement unit and an optional 45 MP camera, allowing point-cloud and image data to be collected during the same flight.

With a measuring range of up to 750 m at 80% reflectivity, the GS-960 is designed for higher-altitude and longer stand-off surveys than compact low-range UAV scanners. This makes it particularly useful for mountainous terrain, long infrastructure corridors, forests, open mines and other locations where flying higher or maintaining more clearance from the ground can improve safety and survey efficiency.

5 cm absolute accuracy at 150 metres

The GS-960 is specified with 5 cm absolute accuracy at 150 m under the manufacturer’s stated conditions. The laser ranging accuracy itself is approximately 0.5 cm, providing precise distance measurements before GNSS and inertial positioning are taken into account.

For real survey work, final accuracy depends on the complete workflow. GNSS correction quality, trajectory processing, aircraft movement, calibration, flight height and survey control all influence the finished point cloud. This makes correct mission planning and post-processing just as important as the LiDAR sensor itself.

Long-range scanning for larger survey areas

The extended working range allows the GS-960 to survey from greater heights than short-range LiDAR systems. Higher flight altitudes can increase the width of each survey strip and reduce the number of flight lines required across large sites.

This is especially useful for mountain mapping, forestry, mines, river corridors and regional terrain surveys where access from the ground is difficult or where operating close to the surface would reduce flight efficiency. Actual usable range will depend on target reflectivity, scan angle and environmental conditions.

Up to 550 kHz point frequency

The GS-960 operates with a configurable point frequency between approximately 100 kHz and 550 kHz and a scan rate of up to 300 lines per second. This allows operators to balance point density, flight speed and area coverage according to the needs of the project.

A higher point frequency can provide denser information across terrain and structures, while lower settings may be sufficient when larger-area coverage is more important than very high point density.

Unlimited laser echoes for vegetation penetration

A major feature of the GS-960 is support for unlimited laser echoes. Multiple echoes allow the system to record several surfaces encountered by a laser pulse rather than only the first object it reaches.

This is particularly valuable in forestry and vegetation surveys. A pulse may interact with the canopy, branches, lower vegetation and potentially the ground below. More return information gives surveyors and forestry specialists additional data for separating vegetation layers and creating ground models where canopy openings allow the laser to reach the terrain.

80 degree field of view

The scanner provides an approximately 80° field of view. This relatively wide scan angle helps create broad survey strips beneath the aircraft and supports efficient coverage during long-range mapping missions.

The final usable swath depends on altitude, terrain and the required accuracy. Flight plans should therefore be designed around the required point density and overlap rather than maximum field of view alone.

High-precision gSpin 310 GNSS and INS

The GS-960 integrates Geosun’s gSpin 310 GNSS/INS positioning system with a 200 Hz IMU update rate. It supports GPS, GLONASS, Galileo and BeiDou satellite constellations and continuously records the position and attitude of the LiDAR payload while the aircraft moves.

The current specification gives approximately 2 cm horizontal and 3 cm vertical positioning accuracy, together with 0.005° pitch and roll accuracy and 0.017° heading accuracy. During processing, this trajectory is combined with the laser observations to place the individual LiDAR points in their correct geographic positions.

Optional 45 MP camera for coloured point clouds

The GS-960 can be configured with an optional 45 MP RGB camera. High-resolution imagery provides visual context alongside the geometric LiDAR data and can be used to create colourised point clouds.

For surveyors, GIS users and infrastructure teams, colour information can make roads, buildings, vegetation, utilities and other features easier to identify during processing and interpretation. Collecting imagery and LiDAR during the same mission can also reduce the need for separate flights.

Topographic surveying and terrain mapping

Large-area terrain mapping is one of the main applications of the GS-960. Its long measuring range and high-precision trajectory system allow survey teams to collect dense elevation information across terrain that may be difficult, slow or unsafe to survey from the ground.

The resulting point cloud can support digital terrain models, engineering design, land planning, volume calculations, hydrological analysis and general geospatial mapping.

Forestry and vegetation monitoring

The GS-960 is particularly suited to forestry work because of its long range and multiple-return capability. Survey crews can capture canopy structure while also collecting information from lower vegetation and terrain beneath suitable openings in the canopy.

These datasets can be used for forest inventories, vegetation monitoring, terrain modelling and land-management projects where both canopy and ground information are required.

Power-line and utility corridor surveys

Power-line inspection is another core GS-960 application. Airborne LiDAR can capture conductors, towers, surrounding vegetation and terrain in three dimensions while keeping the aircraft at a safe stand-off distance from the infrastructure.

The resulting corridor point cloud can support asset mapping, vegetation-clearance analysis, engineering documentation and planning. Similar workflows can be applied to pipelines, roads, railways and other long linear assets.

Mining and quarry surveying

For mining and quarry projects, the GS-960 can be used to map open pits, high walls, stockpiles and changing terrain from the air. Its extended range allows survey flights to maintain greater clearance over steep or hazardous surfaces.

Repeated surveys can produce comparable three-dimensional datasets for progress monitoring, surface analysis and volume calculation in compatible processing software.

Emergency and rapid-response mapping

Geosun also positions the GS-960 for emergency mapping. UAV LiDAR can quickly capture terrain following landslides, floods or other events where ground access may be limited or unsafe.

The ability to work from higher altitude and collect dense geometric information allows response teams to generate up-to-date terrain data without relying solely on ground crews entering affected areas.

Water conservancy and river mapping

The manufacturer’s application material also identifies water-conservancy work as a GS-960 use case. The system can record riverbanks, embankments, flood-control infrastructure and surrounding terrain for GIS, planning and engineering analysis.

LiDAR measures the surfaces visible to the laser and is not a bathymetric system, so underwater depth measurement requires appropriate bathymetric equipment. The GS-960 is primarily useful for the terrain and structures around the water.

DJI M300 M350 multi-rotor and VTOL integration

The GS-960 supports DJI M300 and M350, other multi-rotor UAVs and VTOL aircraft. This gives survey teams flexibility to choose the aircraft according to the size and shape of the project.

A multi-rotor platform is practical for sites requiring vertical take-off, precise positioning and shorter flight lines. VTOL platforms are often better suited to long corridors and large-area mapping where endurance and coverage are priorities.

Lightweight long-range payload

The system weighs approximately 1.6 kg with the 45 MP camera, which is relatively lightweight for a long-range airborne LiDAR payload. The unit measures approximately 21.7 × 9 × 9.9 cm and uses a 24 V power supply with approximately 70 W consumption.

The compact format helps reduce demands on the aircraft compared with much heavier airborne scanning systems, while still providing the range needed for professional large-area surveys.

Data storage and field operation

The current GS-960 product sheet specifies 128 GB data storage. The system is rated for operation from approximately -10°C to +40°C, making it suitable for a broad range of professional field conditions.

Survey crews should plan storage, power, flight time and mission overlap together so LiDAR, trajectory and image data can be collected continuously throughout the complete project area.

Point-cloud processing workflow

The GS-960 works with Geosun point-cloud classification and post-processing software, while optional waypoint mission-planning software can be used to prepare flight routes. GNSS/INS trajectory data is combined with the laser measurements to generate a georeferenced point cloud for further analysis.

The processed data can then be brought into compatible surveying, CAD, GIS, forestry, mining and engineering software according to the required project deliverables.

Who is the Geosun GS-960 for?

The GS-960 is especially relevant for survey companies, UAV mapping providers, utilities, forestry specialists, mining professionals, civil engineers and GIS teams that need greater working range than compact UAV LiDAR systems can provide. Its combination of 750 m range, 5 cm absolute accuracy at 150 m, unlimited echoes and high-precision GNSS/INS makes it suitable for demanding large-area and corridor mapping projects.
