GNSS-Denied
GNSS-Denied refers to an environment where Global Navigation Satellite System signals, such as GPS, are unavailable or unreliable due to jamming, spoofing, or natural interference. This forces navigation systems to rely on alternative methods for positioning and timing.
TECHNICAL DEFINITION
GNSS-Denied describes an operational environment where Global Navigation Satellite System (GNSS) signals, including GPS, GLONASS, Galileo, and BeiDou, are intentionally or unintentionally unavailable or compromised through electronic warfare tactics like jamming or spoofing, necessitating the use of alternative PNT (Positioning, Navigation, and Timing) solutions for military platforms, missiles, and hypersonics to maintain navigation and targeting accuracy.
BACKGROUND
GNSS jamming, including GPS jamming, is an act of overwhelming global navigation satellite systems (GNSS) receivers with powerful radio signals that drown out the signals from the GPS, GLONASS, BeiDou, or Galileo satellite constellations. It renders the receiver unable to calculate its position or time accurately. Such jamming can disrupt various GPS-dependent devices, from vehicle and aircraft navigation systems to precision agriculture and mobile phone networks. In civil aviation, GPS jamming can disrupt ADS-B transmission. GPS jamming is a particular type of GNSS interference.
