Satellites are not just TV shows and internet in areas where cable connections are not available. This is also the wireless communication that the military most deserves. The American army is about to put an entire network of nano-satellites in orbit that will provide its soldiers with communications no matter where they are.
Military engineers are designing a small and inexpensive satellites built under the SMDC-ONE project (ONE stands for Orbital Nanosatellite Effect), whose mission is to provide soldiers with uninterrupted communications, regardless of where they are in the world.
Dr. Travis Taylor, chief scientist in the military space space research division, explains that new nanosatelites can be termed cellular transmitters that will function in space. These devices are designed to withstand the tough conditions of space and are cheap enough to easily replace damaged ones.
The military needs 12 such small orbiting satellites to cover the entire planet. So far, the project is still in a very early stage of development and before the devices are brought into space, engineers have to solve a few problems that have emerged at the design stage.
One of them is the question of the satellite drive. You can not use standard motors because they could explode, destroying the device. The researchers used a 3D printer to create a new engine, filled with liquid nitrogen oxide and equipped with a spark plug. This is a much safer solution.
Military satellites will also be slightly larger than communications satellites. In addition to communication modules, they have optics that allow high resolution terrain imagery to track the movement of enemy troops.
