In 2017 it became clear that the airborne mapping and surveying industry was moving towards LiDAR sensors onboard UAVs; these solutions are very cost-effective for highly accurate and fast terrain data gathering. LiDAR has a number of advantages – including the capability to penetrate vegetation cover and provide real-time data – making it the preferred solution for users who regularly perform corridor mapping, and the mapping of hard-to-access areas.
SureStar, a leading LiDAR manufacturer for both mapping and autonomous vehicle LiDAR sensors, began developing a UAV LiDAR project back in 2016 and has now developed a UAV-based LiDAR sensor.
However, there are considerable challenges associated with UAV LiDAR systems, including potential financial losses associated with: UAV crashes, flight-time limitations due to heavy payloads, and poor point cloud quality. Applanix and SureStar began to work together in 2018 on the Genius drone LiDAR system, in order to provide a viable solution. The Genius drone LiDAR system has been designed and built to achieve the perfect balance of weight, cost and performance.
The Trimble APX UAV GNSS-Inertial solution is a complete hardware and software solution suitable for even the smallest of UAVs. It is comprised of a single-board OEM module (6*6.7 cm, 60 grams), which contains a survey-grade multi-frequency GNSS receiver and high-performance MEMS inertial sensors. Also included is Applanix’ POSPac UAV software for post-processing the collected data.
SureStar R-Fans laser scanner weighs only 738 g, yet is able to detect objects with 10% reflectivity at 200 m. UI-RF software comes with the R-Fans scanner to enable data fusion of flight trajectory and point cloud output in LAS or xyzi format, as well as point cloud visualization.
Together, these integrated products offer a lightweight solution which enables those mapping or surveying with a UAV to produce high-quality deliverables quickly and efficiently.
The Genius drone LiDAR system weighs only 1168 grams, meaning that it can be installed on even very light-weight drones.

Threats analysis along with 3D demonstration of power line, tower and facilities.
Genius is not limited to use only with UAVs. It can be installed on many types of vehicles for high resolution mapping.
SureStar was established in 2005 in China to offer LiDAR mapping solutions. SureStar is the one of earliest lidar manufacturers to be involved in integrated-circuit design specifically for LiDAR signal processing (LSP). The high-performance LSP chips, modular design, and unique semiconductor assembly process make SureStar stand out in product performance, low weight, and low power consumption, as well as high production efficiency. In as early as 2014, anticipating an increasing demand for autonomous vehicle and UAV applications, the SureStar team decided to put more effort into the development of automotive LiDAR and lightweight UAV LiDAR.
SureStar embraces complete and comprehensive LiDAR core technologies and has reported over 100 intellectual property rights (patents, software copyrights and trademarks). Quick roll-out of new products comes from a talented and fast-growing R&D team. The SureStar headquarters and R&D center are located in Beijing, while its production facilities are located in Suzhou, and software team in Hefei. In 2018, SureStar set up a representative office in Wixom City, near Detroit, to provide timely technical support to North American clients. SureStar currently has more than 200 employees, of which more than 50% are involved in R&D and technical support.
Applanix, a Trimble Company (NASDAQ:TRMB), develops, manufactures, sells, and supports products and solutions for mobile mapping and positioning.
