An unmanned aerial vehicle (UAV) (or uncrewed aerial vehicle, commonly known as a drone) is an aircraft without a human pilot on board and a type of unmanned vehicle. 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 on-board computers.

UAS: Wasp® AE RQ-12A:
As per information by avinc.com Weighing in at just over a kilogram, the Wasp AE delivers best-in-class capabilities for an unmanned aircraft system of its size, including stealth-like manoeuvrability, superior imagery, encrypted video and exceptional ease of use. Wasp’s gimbaled payload is mechanically stabilized, enabling it to transmit advanced imagery in high-wind conditions, while its advanced avionics allow operators the option of manual or autonomous navigation. The all-environment Wasp combines hand-launch capabilities with deep-stall landing for operations in confined areas on land or water. The aircraft also includes an integrated landing camera that provides operators with exceptional situational awareness as the aircraft approaches the ground.
This low acoustic and efficient propulsion system enables a flight endurance of 50 minutes. Operators can see incredible detail without being detected. This custom designed autopilot includes a Digital Data Link (DDL) compatible with Wasp, Raven and Puma AE Ground Control System (GCS). This mechanical and digital gimbaled payload features an integrated high resolution EO and 640 x 480 IR camera for superior imagery. An integrated landing camera provides operators with excellent situational awareness during landing. A small, portable, reliable, and rugged unmanned aerial platform designed for front-line day/night reconnaissance and surveillance.  Ruggedized for use on land and sea, Wasp AE is AeroVironment's smallest UAS with a gimbaled EO and IR payload. The motor and motor controller battery, payload and control surface actuators are all replaceable in the field within minutes and without the use of special tool.  This increases the operational availability of each UAS.
UAS: RQ-11B Raven®
As per information by avinc.com The Raven system is the most widely deployed unmanned aircraft system in the world, ideal for low-altitude intelligence, surveillance, and reconnaissance missions that depend on rapid deployment and pinpoint manoeuvrability. Lightweight and simple to operate, the Raven is rucksack portable and can be hand-launched for day or night observation. The Raven has an optional stabilized gimbaled payload, and delivers real-time colour and/or infrared imagery to the ground control and remote viewing stations. Thanks to its advanced avionics, Raven can be operated manually or programmed for autonomous navigation. AeroVironment’s common GCS interfaces with all of its tactical ISR air vehicles reducing the level of training required and decreasing the time and cost involved.
Gimbaled EO/IR cameras with IR illuminator. Digital stabilization. Continuous pan, +10 to -90-degree tilt. Dual forward and side-look EO cameras. Digital stabilization electronic pan-tilt-zoom. Optional: Side-look IR Camera, forward-look IR camera. A lightweight, hand-launched solution designed for rapid deployment and high mobility. The Raven features simple operation. autonomous navigation,
auto land, and an inter-operable system interface. With a wingspan of 4.5 feet and a weight of 4.2 pounds, the hand-launched Raven provides aerial observation, day or night, at line-of-sight ranges up to 10 kilometres.
