“…Magnetic field sensors based on the force effect on a permanent magnet have been used for current sensing. Simple devices such as [39], [40], [41], [42] suffer from poor sensitivity and poor accuracy. However, the old definition of the ampere was based on force, and the Kibble balance was a very accurate instrument.…”

We review recent advances in magnetic sensors for DC/AC current transducers, especially novel AMR sensors and integrated fluxgates, and we make critical comparison of their properties. Most contactless electric current transducers use magnetic cores to concentrate the flux generated by the measured current and to shield the sensor against external magnetic fields. In order to achieve this, the magnetic core should be massive. We present coreless current transducers which are lightweight, linear and free of hysteresis and remanence. We also show how to suppress their weak point: crosstalk from external currents and magnetic fields.

Today Unmanned aerial vehicles (UAV) have found widespread use and may have been using them to capture various events or take photographs of operational areas; but the fact is that UAVs or quadcopters, which are some of these flights, are still at the beginning of their journey and can be future applications will be more widely used. Given the geographical situation and the current situation in the world, the country needs to step up with the world in order to strengthen the defense forces. One of the tools that have been used in recent decades to other tools due to their characteristics and their unique features, including the absence of human casualties, the study and more precise missions, and ... are of interest to many countries, including our country, are unmanned aerial vehicles. Many researchers have been carried out on these devices today. In the same way, our researchers in our country have done a lot of researches on this device in recent years and tried to make these birds with the least cost and with the highest efficiency. This paper also attempts to analyze the flights with the ability to carry the camera. At first, its components, including wings, body, tail, and landing gear, are optimally designed and then aerodynamically and instrumentally analyzed, so that this research used to build these flights species in the future.

“…UAV systems also offer various applications other than mapping such as surveillance, archeological, geohazard studies, monitoring, and fire disaster [10][11][12][13][14][15][16][17][18][19][20][21][22]. The UAV system is equipped with various intelligent sensors such as barometer, Inertial Navigation System (INS), Global Positioning System (GPS), flight control, navigation control, sonar, and infrared and Electronic Speed Controller (ESC) [23][24][25][26][27]. There are many kinds of UAVs available in the market which are affordable.…”

Unmanned Aerial Vehicles (UAVs) can be used for close range mapping. In engineering survey works, the conventional survey involves huge cost, labour, and time. Low-cost UAVs are very practical in providing reliable information for many applications such as road design. UAVs can provide the output that meets the accuracy of engineering surveys and policies, especially for small-scale mapping. UAVs are also a competitive technology which is stable and rapidly developing, same as other surveying technologies. This study investigates the performance of multirotor UAV for road design. This study involves four phases which consist of preliminary study, data collection, data processing, and analysis. This study focuses on the UAV as a tool to capture data of the ground from a certain altitude. The analysis includes UAV flight planning, image acquisition, and accuracy assessment of road design. It can be concluded that UAVs can be used to provide data for road design with reliable accuracy.
