Military satellites were first used as an explorer to capture the images of any enemy or other country's soldiers in the treaty. Satellites are somewhat similar to drones, except that drones need to be piloted manually with human interaction.
Whereas the satellites, once they are in the earth’s orbit, float and rotate around the earth. They use sensors and lenses to capture images. Moreover, satellites require hydrazine-based fuel to continue rotation around the Earth.
According to reports in 2021, there are more than 6,000 military satellites in earth’s orbit. Of those, approximately 3,300 satellites are active.
Why are these Satellites Used?
These satellites are used for military communications and receive signals and images related to ongoing conflicts with armies of different countries. Moreover, it is useful in noticing and tracking other armies' next moves. Apart from this, satellites can provide imagery of forested areas as well, providing the ability to control and secure the area. In addition, these satellites are useful in general use for other than military purposes, such as weather forecasting.
What Will Be the Future of Satellites?
Speaking about the growing military bases of all countries and how the satellites provide ease of operation and communication between military personnel, the future market for military satellites is, without a doubt, bright. The military satellites market is expected to grow at a CAGR of 6.7% during the 2022–2028 period.
Recently, in August 2022, the US and New Zealand launched their second joint military satellite, which is going to be used as a spy. In addition, growing technologies such as high-resolution cameras and sensors are increasing the use of such technologies in satellites as well, which results in more accurate reports and data for military personnel. Other than this, reusable rockets and satellites are cutting the cost of launching the satellites, resulting in higher demand.
Are they Costly?
It depends on the requirements of the army and the features of the satellites. Mostly, they range between around INR 4–5000 crore, which is costly.
Final Thoughts
Whether it is for general purposes or for safety and security concerns, every country uses satellites. There are key market players such as Airbus S.A.S., Lockheed Martin Corp., Northrop Grumman Systems Corp., Thales S.A., and The Boeing Co. that are contributing to the military satellite market's growth.
