Brushless AC Electric Motor
BRUSHLESS DC ELECTRIC MOTOR (BLDC MOTORS, BL MOTORS) also known as ELECTRONICALLY COMMUTATED MOTORS (ECMs, EC motors), or SYNCHRONOUS DC MOTORS, are synchronous motors powered by DC electricity via an inverter or switching power supply which produces an AC electric current to drive each phase of the motor via a closed loop controller . The controller provides pulses of current to the motor windings that control the speed and torque of the motor. The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor , or an induction (asynchronous) motor . The advantages of a brushless motor over brushed motors are high power to weight ratio, high speed, and electronic control. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles.

Intelligence, Surveillance, Target Acquisition, And Reconnaissance
ISTAR stands for information , surveillance , target acquisition , and reconnaissance . In its macroscopic sense, ISTAR is a practice that links several battlefield functions together to assist a combat force in employing its sensors and managing the information they gather. Information
Information
is collected on the battlefield through systematic observation by deployed soldiers and a variety of electronic sensors. Surveillance, target acquisition and reconnaissance are methods of obtaining this information. The information is then passed to intelligence personnel for analysis, and then to the commander and his staff for the formulation of battle plans. Intelligence is processed information that is relevant and contributes to an understanding of the ground, and of enemy dispositions and intents

Air Strato
AIRSTRATO is a solar powered medium-sized unmanned aerial vehicle currently in development at ARCA . There are currently two variants available, AirStrato Explorer with a flight ceiling of 18,000 m and AirStrato Pioneer with a flight ceiling of 8000 m. It can cary a 45 kg payload consisting of surveillance equipment, scientific instruments or additional battery pods for extended autonomy. The first prototype maiden flight took place on February 28, 2014. It was equipped with a fixed landing gear. Two more prototypes were constructed that lacked a landing gear. Instead ARCA opted for a pneumatic catapult as a launcher and landing skids and a recovery parachute for landing. Both prototypes performed take-off and landing testing and low altitude flights

Sun
in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Irradiance may be measured in space or at the Earth\'s surface after atmospheric absorption and scattering . It is measured perpendicular to the incoming sunlight. TOTAL SOLAR IRRADIANCE (TSI), is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere . The solar constant is a conventional measure of mean TSI at a distance of one astronomical Unit (AU). Irradiance is a function of distance from the Sun, the solar cycle , and cross-cycle changes

Unmanned Aerial Vehicle
An UNMANNED AERIAL VEHICLE (UAV), commonly known as a DRONE, is an aircraft without a human pilot aboard. UAVs are a component of an unmanned aircraft system (UAS) ; which include a UAV, a ground-based controller, and a system of communications between the two. The flight of UAVs may operate with various degrees of autonomy : either under remote control by a human operator or autonomously by onboard computers. Compared to manned aircraft, UAVs were originally used for missions too "dull, dirty or dangerous" for humans. While they originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications, such as policing, peacekeeping, and surveillance, product deliveries , aerial photography , agriculture, smuggling, and drone racing
