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 …

Sensors are usually thought of in terms of physical devices that receive and respond to electromagnetic signals – from everyday sensors in our smartphones and connected home appliances to more advanced sensors in buildings, cars, airplanes and spacecraft. However present day physical sensors are severely limited in range to continuously …

Military today is more reliant on space than ever before including ISR, Electronic warefare, Communications, Command and control and ballistic Missile defence. The joint warfighter uses space to satisfy an ever expanding and diverse set of requirements such as  cutting the fog and friction of war or to enable net-centric …

US, Russia and China are in race for Hypersonic Weapons that shall provide prompt global strike capability.  Russia’s Avangard hypersonic missile system became operational in Dec 2019, defence minister Sergey Shoygu has said. The intercontinental weapon can fly 27 times the speed of sound and, unlike a regular missile warhead, …

Remote sensing of the environment, and especially Earth observation, is witnessing an explosion in terms of volume of available observations, which offer unprecedented capabilities towards the global-scale monitoring of natural and artificial processes.   Satellite imaging payloads, mostly operate a store-and-forward mechanism, whereby the captured images are stored on board …

The warning bells has ringed in US, as  Kim has finally succeeded in developing an ICBM operational capability through which it can deliver a nuclear weapon anywhere in the United States, according to analysis based on Images released by North Korea. North Korea released dozens of photos and a video …

Search and Rescue (SAR) is receiving a lot of attention recently due to several high-profile incidents on land, in the air and at sea. Flight MH370 left Kuala Lumpur was bound for Beijing in March 2014 when it disappeared, with 239 people on board. Even after the largest and most …

The space is also becoming increasingly militarized many countries are developing killer microsatellites and other antisatellite weapons (ASAT) that could be used to damage other satellites.   Potential adversaries have the ability to focus on temporary, reversible effects such as jamming or dazzling which denies or disrupts the satellite versus …

Historically, there was a necessity for a third party that demanded a payment to perform transactions or submit information to ensure the accuracy of transactions and create a reliable history. Blockchain eradicates the need for an intermediary through creating a trustless medium of exchange and immutable public ledger. It creates …
