Under Electronic warfare Cyber threat, Militaries developing secure, anti-jam mobile, and high-bandwidth Military Satellite Communications anywhere in the world

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Satellite communications networks servicing large number of users comrise of  user terminals, satellites and a ground …

Militaries employing UAV swarms under Network Centric Electronic Warfare concept to counter A2/AD environment

All modern forces depend on unimpeded access to, and use of, the EM spectrum in conducting military operations. Therefore, there is a requirement to gain and maintain an advantage in the electromagnetic spectrum by countering adversary’s systems and protecting one’s own systems.  Electronic Warfare has become now a means to …

Next Quantum Cryptology (QKD) revolution is Quantum Communications between Drone and ground and between drones

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that if Eve attempts to intercept and measure Alice’s quantum transmissions, her …

High Frequency(HF) communications technologies enable Wideband High Frequency net-centric, beyond line of sight communications in battlefield

High frequency (HF) band covering frequency range between 2 to 30 MHz provides over-the-horizon communications with ranges over thousands of kilometers through skywave propagation. It offers an alternative to satellite communications (SATCOM) for many commercial and military applications that requires non-line-of-sight communications.   High Frequency (HF) band  has been considered …
