// UNMANNED SYSTEMS AND NEXT-GEN WARFARE TERM

Anti-Satellite

Anti-satellite refers to weapons or technologies designed to disable, damage, or destroy artificial satellites orbiting Earth. These systems aim to degrade an adversary's space-based capabilities like communication, navigation, and intelligence gathering.

TECHNICAL DEFINITION

Anti-satellite (ASAT) capabilities encompass kinetic kill vehicles, electronic warfare, cyber attacks, and directed energy weapons specifically developed to neutralize or degrade adversary artificial satellites, thereby impacting space-based intelligence, surveillance, reconnaissance (ISR), navigation (GNSS), and communication (SATCOM) assets critical for national security and military operations.

BACKGROUND

Anti-satellite weapons (ASAT) are space weapons designed to incapacitate or destroy satellites for strategic or tactical purposes. Although no ASAT system has yet been utilized in warfare, a few countries have successfully shot down their own satellites to demonstrate their ASAT capabilities in a show of force. ASATs have also been used to remove decommissioned satellites.

SYNONYMS & ALIASES

  • ASAT
  • Counter-Space Weapon
  • Satellite Killer
  • Space Weapon

USAGE NOTE

Development and testing of anti-satellite weapons are highly controversial due to the risk of creating significant space debris, which threatens all orbital assets.
