Sequoia's components (GPS, IMU, Magnetometer)


The Sequoia sunshine sensor has a built-in GPS module. While the GPS modules integrated into drones make it possible to keep an eye on their position during a flight, the Sequoia GPS module allows the position of each captured image to be identified. The GPS module makes it possible to significantly increase the precision of the data collected by the sensor without using data collected by the transport platform: plane, drone, tractor, etc. The integration of a GPS module into the sensor fulfills the objective of rendering Sequoia fully autonomous, thus dispensing with image monitoring by the autopilot of the drone. As a result, it can be used in any drone.


The Inertial Measurement Unit (IMU) is a unique feature of the Sequoia sensor. This technology (patent pending), installed in a multispectral sensor for the first time ever, makes it possible to refine the precision of the image calculations by providing data on the orientation of the sensor. The inertial measurement unit thus makes it possible to compensate for variations in the orientation of the sensor due to the movements of the drone. The sensor therefore no longer needs a stabilized basket and can be directly hooked up to any drone. The sunshine sensor also has an on-board Inertial Measurement Unit.


The magnetometer enables the sensor to maintain a heading. Acting like a compass, the magnetometer indicates north to the sensor and thus provides a direction to the captured images. This element fulfills the objective of making Sequoia adaptable to all drones, particularly those that do not have a communication interface with their on-board sensors.
