The China National Space Administration (CNSA) was established in 1993 as China’s civil space authority. By the end of 2024, China operated more than 1,060 active satellites in orbit, a count that has grown more than six-fold since 2015. Chang’e-4 achieved the first landing on the Moon’s far side in 2019. Micius (Mozi), launched in…

Field telephones were standard on the battlefield from the 1910s through the 1980s, with the EE-8 field telephone (1930s–Vietnam) offering a 7-mile range. The SCR-300 Walkie-Talkie, developed by Galvin Manufacturing (Motorola) in 1940, was the first backpack FM radio with about a 3-mile range. SINCGARS, fielded by the U.S. Army in the late 1980s, has…

Telstar 1 (NASA) transmitted the first live television signals via satellite in 1962, linking Europe and North America. Syncom 2 became the first geosynchronous satellite in 1963, and Syncom 3 in 1964 broadcast the Tokyo Olympics to the United States. Intelsat I (Early Bird) was launched in 1965 as the world’s first commercial communications satellite…

The four pillars of quantum technology are quantum computing, quantum communication, quantum sensing (metrology), and quantum simulation. In 2016, China’s Micius satellite demonstrated satellite-based quantum key distribution by distributing entangled photons between ground stations over 1,200 km. IBM aims to build a 4,000+ qubit machine by 2025 and demonstrated a 433-qubit processor in 2022. D-Wave’s…

Global government and military Satcom spending is projected to grow about 7–10% annually, rising from roughly $50 billion in 2024 to $64 billion by 2030. The Ukraine conflict underscored Satcom’s importance, with Starlink keeping forces online for combat and coalition operations. Militaries are shifting to enterprise Satcom architectures that blend military and commercial satellites across…
