Actuator

An actuator is a type of motor that is responsible for moving or controlling a mechanism or system.


Active Isolator

Active isolation device incorporates real-time recording instrumentation on the ground integrated with some form of actuator contolling the device to which it is mounted.


AHRS

Attitude and Heading Reference System.


Autonomous

Some aircraft are controlled not by a human sending radio signals but by internal programming that tells it where to fly using its on-board GPS system to fly from one predetermined point to another.


Advanced Micro Processors

A microprocessor is a computer processor that incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit. Since 2011 low cost, low power ARM devices capable of 10,000 MIPS are available, ( MIPS Millions of instructions per second )


Backlash

The maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence.


Brushless Motor

A brushless DC motor is essentially a dc motor without the mechanical commutation of the brushed dc motor. A sensor and electronic controller take the place of the commutator producing better efficiency.


COAs

Certificates of authorisation, which are approvals to fly UAVs domestically granted by the Federal Aviation Authority


Control Loop

Most automated systems use some form of control loop for dynamic adjustment to maintain a constant, common applications include:
Temperature thermostat
Vehicle cruise control
Aircraft autopilot
Boat bilge pumps


Drone

A autonomous pilotless aircraft or missile


GCS

Ground Control Station


Gimbal

A pivoted support that allows the rotation of an object about an axis.


GPS

Global positioning system


Gimbal

A gimbal is a pivoted support that allows the rotation of an object about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support.


Gyroscope

(from Greek "to look") is a device for measuring or maintaining orientation, based on the principle of preserving angular momentum


IMU Sensor

An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes, sometimes also magnetometers.


Line-of-Sight

The line between two points; specifically : the straight path between a camera and an object when unobstructed.


LWIR

Long Wave Infrared


MFTD

Multi Function Threat Detector


MWIR

Medium Wave Infrared


Passive Isolator

An isolator which has no feedback capability between the device and the separate grounded element.


PID Controller

Proportional–Integral–Derivative Controller, P accounts for present values of the error, I accounts for past values of the error, D accounts for possible future values of the error, based on its current rate of change. Basically take a control loop add to this some further refinement by measuring the error size, duration of the error and rate of change then you have a highly effective level of automation.


SWIR

Short Wave Infrared


UAS

Unmanned Aerial System.


UAV

Unmanned Aerial Vehicle


UCAV

Unmanned Aerial Combat Vehicle
