WayPoints navigation:

Drone waypoints navigation

The WayPoints navigation is one of the most important features of our systems.

It allows to plan the flight very accurately upstream -from a computer (PC) or tablet (Android)- and achieve it at the site of the shooting thanks to the GPS functionalities.

The flight plan can be prepared in the office or even on site, based on geo-referenced maps, such as Google maps for example.

It can then be stored in the memory of the drone to be recalled at any time without having to use the computer or the tablet again, through a few simple buttons of the remote controller.

Several different navigations can be saved and loaded with the drone radio control (even during the flight) to be executed by the aircraft.

WayPoints generator can very easily create navigations that can be changed later.

GPS positioning:

GPS positionning and navigation

With high-performance GPS receiver systems, our drones are able to receive not only the GPS signals of the American GPS (Global Positioning System), but also those of the GLONASS (Global Navigation Satellite System Russian) constellation as well as the Chinese Beidou system.

The accuracy of these data is further enhanced by the use of EGNOS (European Service Geostationary Navigation Overlay) which completes the availability of the RPAS location information.

The advantage to receive and operate several different navigation systems, makes possible for our drones to position faster and much more accurate in space.

The geographical location in 3D is very fast even in distant areas, as our drones capture enough satellites to determine their position accurately. It is not rare to receive 12 to 16 satellites simultaneously.

A strong GPS signal is necessary in order to have a perfect 3D positioning in the space used for the automated flight features of our drones.

Hyper-spectral and multi-spectral cameras:

Drone assisted agriculture selective harvesting

Visible light by the human eye is located in a range of wavelenght from 400nm to 700nm. A multi-spectral / hyper-spectral camera captures the light into its component parts and covers the wavelength invisible to the eye.

Each component is then associated with its wavelength. In simple words, the hyper-spectral and multi-spectral camera sensors collect information in the form of a set of images.

Every frame represents a range of wavelengths of the light spectrum, also known as spectral band. These images are then combined to form a hyper-spectral cube of three dimensional data which allows processing and analysis.

The software processing of such data then allows to represent visually understandable form and targeting desired wavelengths.

Hyperspectral and multispectral imaging technology embedded on drones provides high-precision diagnostics for agriculture, helping to detect crop diseases, weeds, vermin & insects invasion, irrigation problems and environmental stress. This makes easier the management of the necessary treatments that are precisely targeted to the concerned parts of the fields.


Thermal imaging cameras:

Drone thermal imaging

Thermal cameras record the various infrared radiation emitted by the body or objects which vary with their temperature.

Infrared thermography is a technique that provides a thermal image of an object or a place by analyzing its infrared radiation.

The image thus acquired is called a “thermogram” . The thermogram is a video file enriched with metadata for each pixel. The metadata contain the temperature details of the filmed object, at the time of the video recording.

Thermal cameras can be used for thermography, for search & rescue (SAR) or for security & surveillance operations.

Gyrostabilized gimbals with dual cameras (HD & Infrared):

Gyrostabilized gimbals with dual cameras (HD & Infrared) for RPAS drones

The optical zoom (30X) of the HD video camera embedded on our gyrostabilized gimbals can clearly visualize an object at more than one or two kilometers.

Switching to the infrared is instantly and remotely performed by the pilot allowing to combine the powerful HD color vision to the thermal image in a 360° swiveling gimbal.

The 8X digital zoom of the infrared thermal camera and the choice of colors (allowing to better highlight the temperature differences) are both remotely controlled from the ground.

Our gyrostabilized gimbals equipped with dual cameras (HD and Infrared/thermal) and their powerful zoom, are used for security & surveillance operations & in the SAR (search and rescue) domain.

Photogrammetry based on aerial images:

Modelisation 3D sur base d'images

Agisoft PhotoScan Pro is available as an option to all our aircraft and enables UAV operators, architects, surveyors and many other professionals to automatically generate clouds of dense points, 3D models, geo-referenced orthomosaic,  Digital Terrain Model (DTM/DEM), and Digital Surface Models (DSM) from aerial photographies.

Global Mapper: GIS for everyone


Global Mapper  software is an affordable and easy-to-use GIS application that offers access to an unparalleled variety of spatial datasets and provides just the right level of functionality to satisfy both experienced GIS professionals and beginning users.

Equally well suited as a standalone spatial data management tool and as an integral component of an enterprise-wide GIS, Global Mapper is a must-have for anyone who works with maps or spatial data.

Global Mapper is available as an option to all our aircrafts .

Embedded LIDAR system:

Light Detection and Ranging LIDAR on a drone

Light Detection and Ranging (more commonly called LIDAR) is a laser-based remote sensing technology. It is widely used in the domain of geographical information system (GIS) for surveying and mapping natural resources and infrastructures.

LIDAR is well known in the domain of producing high-resolution maps in remote sensing, atmospheric sensing, geomatics, geography, geomorphology, archeology, forestry, contour mapping, laser altimetry, geographic infomatics and related sciences that are relying on high accuracy definition of terrestrial three-dimensional points position and the extremely precise & faithful calculation of the distances and angles between them.

One of the specific features of the LIDAR is that it can penetrate the vegetation, and “see” what is underneath.

Our FOX-C8 HD drone is delivered ready to use with an embedded LIDAR and the software to produce the geo-referenced point cloud.

GPS-RTK positioning:

Drone GPS-RTK positioning

Reaching a centimeter level positioning accuracy in the data collected during drone aerial surveys is essential for geomatics-related applications.

Used in topography, cartography, geodesy, geography, hydrography and all areas related to these sciences, the accuracy of this information is essential.
Our RTK (Real Time Kinetics) positioning systems are designed to achieve this accuracy by implementing GPS L1 – RTK receivers based on the constellations of GLONASS, Galileo Beidou and systems like SBAS (satellite-based augmentation system).

They also incorporate the improvements of the EGNOS system, well known in the field of GNSS (Global Navigation Satellite System) in which the accuracy of GPS positioning is important as well.

A ground station is in permanent communication with the drone allowing a continuous position adjustment of the RPAS (Remotely Piloted Aerial System) during the flight.
Our RTK GPS receivers are fully integrated low consumption components based on measurements of the carrier signal’s phase, rather than the data of its content and combine it with the information transmitted from the ground station in order to continuously perform the necessary corrections and achieve the centimeter level positioning accuracy.
