Use Case - Precise large scale terrain mapping under tropical rain forest with the Qube 240 LiDAR and Trinity F90+ UAV

Creation of a Digital Terrain Model using a LiDAR sensor in cooperation with Rocketmine

New ways for aerial LiDAR mapping – the Qube 240 with the Trinity F90+ UAV

Light Ranging and Detection (LiDAR) sensors, partly traded as the key technology of the future for autonomous driving are also the first choice for highly productive survey tasks.

Until recently, LiDAR payloads were hardly affordable for SMEs due to their high cost. This is exactly where Quantum-Systems comes in and offers a geomatics grade LiDAR scanner integrated into the payload compartment of the Trinity F90+ drone including software package without having to compromise on data quality.

The Trinity F90+ in combination with the Qube 240 LiDAR payload offers 1 hour of flight time and safe VTOL (Vertical Take-Off & Landing). The LiDAR sensor and the long flight time are key for a positive ROI.
In comparison, LiDAR missions by manned aviation are on average 10x more expensive and considerably less accurate.

The Qube 240 LiDAR Payload with GPS Dome Antenna. It  provides essential information for surveying and mapping by generating an accurate 3D image of the process environment through 240,000 distance measurements per second.

Why using the Quantum-Systems solution for this mission?

We partnered with Rocketmine to pioneer new solutions for mapping. Rocketmine is a global drone data service provider, offering full turnkey drone solutions across continents for multiple sectors including mining, agriculture, engineering, renewables, security, and medical to name a few.

The task was to survey an area of 6,500 hectares in an equatorial jungle environment in Ghana / West Africa. This extreme operational setting provided an ideal testbed for the use of our Trinity F90+ VTOL drone solution in combination with the Qube 240 LiDAR payload.

The dense jungle environment is problematic for conventional photogrammetric survey techniques and RGB sensors, as they cannot penetrate the various tree layers of the terrain.

As the first active deployment of a Quantum-Systems drone solution in the region, Rocketmines’ team was able to pioneer the use of this groundbreaking technology and quickly gather relevant data to accomplish the mission goals.

Mapping 65 sqkm with a LiDAR Sensor is possible within 4 days with a UAV

Here you can see a part of the primeval forest to be captured at the first starting point. It is almost impenetrable jungle, at least to capture it with conventional surveying methods to the centimeter. To acquire useful data in this area, the LiDAR sensor must penetrate several vegetation layers.  

The mission goals:

  • Create digital orthophotos for the area of interest (AOI) à 65 sqkm in total
  • Create a digital terrain model (DTM) for the AOI
  • Mark contour lines with 0.5m isohypses
  • Create a watershed simulation with the collected data

    Mission challenges

    • Large areas with no take-off and landing sites in the center of the AOI
    • Hot and humid climate conditions (40° – 45°C)
    • Most part of the AOI is covered with dense tropical rain forest.

    The Quantum-Systems Trinity F90+ with the Qube 240 LiDAR Payload during the Project in Ghana.  60 minutes of flight time with one charge are possible. Thanks to electric vertical take-off and landing capabilities handling in demanding environments is a breeze.

    The benefits of a sUAS for mapping missions

    By using the Trinity F90+ it was possible to survey the extensive area within a short time. Compared to a copter drone as the carrying platform, which has significantly less endurance, the flight time of 60 minutes is the decisive advantage. In combination with the vertical take-off capability, there are also no restrictions regarding the take-off and landing area.

    The use of manned solutions would not only have been more expensive by a factor of 10 due to the increased logistical requirements but would also have been significantly worse in terms of data quality due to an accuracy of only 20 cm horizontally and 10 cm vertically.

    The data the LiDAR Sensor delivered offers a deep insight into the local environment in terms of elevation. The complete point cloud vs the reduced ground-level data is shown in the slider above.

    How we performed the mission

    The area was mapped with a total of 20 flights (300-350ha per flight) in 100-120  meters flight altitude.

    The final data had an overall accuracy of 2.32 cm in elevation. With the Qube 240 LiDAR payload,
    we were able to record a total of 11,1 billion points and 2,6 billion ground points from the 6,00 hectares surveyed. After post-processing, we were able to acquire 40 ground points per square meter under dense vegetation.

    A digital terrain model was created using this data set, including a watershed simulation to get situational awareness.

    Data Processing was done with Applanix PosPac and YellowScan Cloudstation to process terrain models.

    The slider shows the entire region with optional 0.5 m and 2 m contour lines to make a final estimate in terms of surface water distribution.

    The captured data enables sustainable management, as well as preventive protective measures for local emergencies. Due to the manageable effort, the data acquisition in such difficult terrain is a suitable instrument to guarantee high data quality and information for decision making with minimal investment.

    Mapping 6500ha in 20 flights is incredible and a real optimization in terms of planning efforts!  The Trinity F90+ & Qube 240 Combo is a beast of a setup!””

    Discover our eVTOL innovation

    A drone is a drone? It is not that simple.


    The Quantum-Systems eVTOL fixed-wing  sUAS unite the convenient handling of a multi-rotor drone and the efficient aerodynamics of an airplane into one system – making them unique.  

    “Automatic transition aircraft” is how Quantum-Systems calls this innovative and patented category of dronesAfter the vertical take-off and reaching the desired flight altitude, the drone has a short phase of transition. During this transition phase, the rotors, driven by electric motors, swivel from the vertical take-off position to a horizontal flight position. The patent for this innovative swivel mechanism and the unique transition technology was granted in 2012. 

    Our sUAS fly as efficiently as a fixed-wing airplanbut allow for the easy vertical take-off and landing like a multi-rotor drone. No runway and no extra equipment are needed for take-off or landingThey land smoothly and controlled on their shock absorbing landing gear. This means reduced harm on the sUAS and sensors for an extended product life. 

    All our systems are designedengineered and manufactured in Germany. We operate out of our Headquarter in Gilching, close to Munich, ensuring short communication lines between the key functions.  


    Easy and safe handling

    A push of a button is enough and the UAV will do its assigned job. The remote control has a clean layout without confusing switches and levers. The TrinityF90+ and the remote controller work together seamlessly to get your job done automatically, while still providing emergency override capabilities.

    Thanks to Quantum’s sophisticated electric VTOL design your investment is never in danger due to a flawed hand launch or a rough belly landing.


    Reliable and integrated design

    We designed the TrinityF90+ as a product that meets the requirements of professionals. We started from scratch with a highly integrated industrial product in mind.

    You can see the result in every detail, such as the optimized electric layout, the efficient cargo container or the clean finish of the outer shell. It truly showcases the best of German engineering.


    Longest flight time in its class

    The ability to switch to gliding mode enables the TrinityF90+ to directly benefit from an enhanced long range capability. We dedicated many hours to optimize the wing geometry to push the glide ratio to an astounding 14:1!

    Using only one specially-designed motor in the rear fuselage increases the flight time far beyond current industrial UAVs by reducing energy consumption to a minimum.


    Small footprint

    The TrinityF90+ comes “ready to fly” (RTF) in a moulded transport case which offers enough space for the whole package with room to add two optional battery packs, accessories, and a tablet PC.

    A padded cover with convenient carrying options makes it easy to transport the package to the farthest operation area. At a size of 100x83x27cm it can be stowed away easily.
