The size and scope of the drone market is booming, with new applications appearing every other day. Drones can be found everywhere, from the delivery of mail or packages, to entertainment for all ages, to security monitoring, to the management of agriculture or industry, to the exploration of a new world of aerial photography.
At first, most drones were simple toys. Recently, however, their flight capabilities have improved significantly, making them safer, more stable, and easier to maneuver, making them increasingly useful in real life.
Key to these capabilities is the use of high-performance MEMS sensors, so the sensor market in uas is growing rapidly:
The market for sensors used in drones and robots is growing strongly and is expected to reach $709 million by 2021, with a compound annual growth rate of 12.4 percent from 2018 to 2021, according to Yole's sensors for drones and robots report.
A high-performance MEMS sensor and advanced software are essential to make drones more than just toys and "even better". The high-precision inertial measurement unit (IMU), pressure sensor, magnetometer, special sensor node (ASSN) and data fusion among sensors on advanced uav have direct and substantial influence on its flight performance.
Limited by size and harsh environment and operating conditions, such as temperature fluctuation and vibration, the requirements of the sensor are raised to a new level. MEMS sensors must minimize these effects and provide accurate and reliable measurements.
Methods to achieve excellent flight performance include: software algorithms (such as sensor calibration and data fusion), mechanical system design (such as vibration reduction), and the selection of MEMS sensors according to the requirements and requirements of uav manufacturers. Let's focus on MEMS sensors through some examples.
