![]() The M300 RTK is equipped with ToF sensors that provide real-time information on the surroundings of all six sides of the aircraft. Infrared ToF sensors resolve the distance to an object using time-of-flight techniques, measuring the round-trip time of an infrared light signal. Forward / Backward / Left / Right: 0.7 - 40 m.If one or more of the sensor pairs are down, the ToF sensors and the remaining vision sensors can still keep the drone functioning safely. The vision sensor pairs provide binocular machine vision, which senses changes in the aircraft’s position and attitude, visually positioning the aircraft while helping it sense obstacles. Meanwhile, the compasses are backed up by the two antennas in the RTK modules, so that in the case where the RTK modules are blocked, the compasses can still help the drone maintain course. The M300 RTK has two compasses to ensure that it continues on the right course even if one of the compasses fails. Dual CompassesĪ compass provides heading information for the drone. The M300 RTK’s GNSS module supports GPS, GLONASS, Beidou, and Galileo satellite positioning systems, and is also backed up by the dual RTK antennas, providing the aircraft with accurate positioning capabilities wherever the mission takes place. In addition to maintaining the drone’s heading, the dual RTK antennas also back up the compasses so that the drone can safely and stably navigate complex environments with electromagnetic interference, such as near power lines or metallic structures. The RTK system is also capable of writing centimeter-level accurate metadata in the images taken, which meets the high accuracy requirements of the surveying and mapping industry. These data allow the aircraft to perform actions such as flying with manual commands through the remote controller, following an automated flight path, or hovering steadily and precisely. The Real Time Kinematic (RTK) system is a positioning system that generates aerial data including latitude, longitude, and altitude readings for the drone’s flight control system. The M300 RTK’s dual barometer redundancy design allows the drone to switch to the backup barometer if the primary one fails, ensuring flight stability and aircraft reliability. ![]() Dual BarometersĪ barometer determines relative altitude based on atmospheric pressure and provides precise altitude readings for the aircraft. In the unlikely case that the main IMU fails, the backup IMU will activate within two hundred milliseconds to maintain flight safety and reliability. The M300 RTK is designed with an industrial-grade IMU redundancy, in addition to fault diagnostics mechanisms and redundancy switching algorithms. Flight Control Sensor Redundancy Dual Inertial Measurement UnitsĪn inertial measurement unit (IMU) measures the aircraft’s real-time three-axis acceleration and angular velocity, and helps calculate the aircraft’s velocity, position, and attitude angle. These redundancies and safety mechanisms include dual flight control system sensors, dual control signal links, dual intelligent batteries, dual transmission links, obstacle sensor system redundancies, and three-propeller emergency landing. The Matrice 300 RTK platform is designed with extensive system and sensor redundancies to maximise flight safety and reliability.
