Satellite imaging is considered the most efficient way to monitor the planet. The EO industry is addressing social, economic, and environmental challenges. Initially, the use of satellite imaging was confined to defense and intelligence applications in the government sector. However, with time, the scenario has changed, and it is now used extensively for civilian purposes as well. Landsat, launched in the early 1970s, was the first satellite system used for civil imagery. Following the launch of this satellite, many companies started developing products and services to cater to civilian needs,including land and coastal applications.

Automated container terminals use container handling equipment that requires no human interaction and can be operated using hardware, software, and terminal operating systems (TOS). The first container terminal with full automation features became operational two decades ago. The initial automated container terminal was in the Netherlands, (ECT Delta). The container terminals are built with automated stacking cranes (ASCs) and some terminals use automated guided vehicle (AGV).Automated container terminals are intended for the handling and stacking of cargo into or out of container. Shipping ports and container terminals play a crucial role in facilitating global trade. The use of automation has boosted the volume of ship-borne world trade significantly. Despite these facts, there are several containers terminals in the marine industry, and most of the companies remain small with minimal market share. Most of the cargo is transported in huge ships (also called mega ships). Shipping is widely popular in international trade as it remains the cheapest

means of transport across borders and continents.

Attack helicopters are aerial maneuver platforms usually employed to engage targets using weapons systems. Apart from conducting attack missions, such helicopters are also used for reconnaissance and security operations. They are capable of rapidly deploying mass combat firepower using weapons and supporting the ground forces during critical times for effective battle outcome. They also enable the commanders to reach far-stretched battlefield areas owing to their mobility and flexibility.As of 2016, over 19,480 attack helicopters have been deployed by defense authorities across the globe. A few countries such as the US, China, Russia, India, South Korea,Japan, and Italy possess powerful and advanced attack helicopters, which provide them an edge over other countries. In addition, these countries comprise approximately 50% of the total number of attack helicopters globally.

Benefits associated with having a heliport or helipad nearby are significant, especially when it comes to emergency situations and supporting offshore activities. Also, the presence of heliports improves the economic condition of the state/region by facilitating air tourism. These functionalities are carrying out a major change in the overall growth dynamics of the global market for heliports. Though the sector is still in its nascent stages of development, the possibilities of reduced noise levels from helicopters, safer landing and take-off with effectual lighting technologies, and floating helipads are changing the way people look at heliports and can result in worldwide acceptance and growth of the heliports market.

A rocket launcher is any weapon system that launches a rocket/missile-propelled projectile. Rocket launchers come in various sizes, shapes, and uses. Depending on the method of application, they can be classified into infantry variant rocket launchers like man-portable and large-scale variants like vehicle-mounted rocket launchers. While man-portable rocket launchers can be carried by an individual or group of individuals to the site of operation, vehicle-mounted rocket launchers are the ones that are mounted on any kind of vehicles such as aircraft, ships, trucks, tankers, and armored vehicles.

Avionics are electronic systems used in aircraft to communicate, navigate, and support various complex flight applications. They are the most expensive and critical components in a modern aircraft. Modern avionic systems also aid in improved navigation and routing, provide enhanced situational awareness to pilots, and improve the air traffic management (ATM) process. There is an increasing demand for advanced high-performance avionics in the military sector.

Military aircraft either consist of rotary-wing or fixed-wing aircraft that are used for combat missions or for the transportation of military personnel and military supplies. Many of the global military aircraft fleets are in service for decades. This aging fleet of aircraft needs to be upgraded and retrofitted with modern aircraft systems and components to extend their service life for modern combat and strategic missions.

VTOL aircraft are capable of vertical take-off, landing, and hovering in the air. These can be classified as fixed-wing, rotorcraft, powered-lift aircraft that use powered rotors such as tiltrotor, cyclocopter, tail-sitter, tiltwing, and fan-wing. VTOL aircraft are also capable of short take-off and landing (STOL), conventional take-off and landing (CTOL), and short take-off and vertical landing (STOVL). Apart from VTOL helicopters, the other two types of VTOL aircraft that are being used are

2007 年以来，航运市场运力供给过剩情况逐渐严峻：2016 年散货船、油船、集装箱船三大船型运力较 2007 年增长了 79.9%，而相应的货物周转量仅增加 28.3%。随着航运市场低迷的延续，以及航运供需两端差距逐步扩大，航运运力供给的增长正逐步放缓。Clarksons 预计 2017 年三大船型运力增速将从 2010 年的 10.3%缩减到 2.3%左右。 

Sleeping pods: A sleeping pod is a comfortable seat or, sometimes, a luxury room that can be availed by passengers at airports at a certain cost.A sleeping pod can be offered as single occupancy or shared occupancy, depending on the size of the pod offered at airports. Currently, the single occupancy sleeping pod segment is driving the market as it is more flexible for airport operators to

deploy at any part of the terminal and overcome the terminal space constraint.
