)
GPS jamming, a technique used to disrupt navigation signals, has been employed in military operations, impacting adversaries’ accuracy in targeting.
Israeli Tactics in Response to Iranian Threat:
Israeli intelligence utilized GPS jamming to confuse Iranian missile targeting teams prior to Iran’s attack on Israel.
Past Instances of GPS Denial:
During the Kargil conflict in 1999, the US denied GPS data to India, hindering Indian military operations.
US Employment of GPS Jamming:
The US utilized “selective availability” technology during the Kargil conflict, degrading GPS accuracy for the Indian military.
Development of Indigenous Navigation Systems:
In response to GPS denial, India developed NavIC, an independent satellite navigation system, ensuring precise positioning and navigation.
Current Scenario:
Israel’s jamming of GPS signals during Iran’s anticipated attack led to confusion among Iranian missiles, resulting in a high interception rate.
Impact and Countermeasures:
Despite Iran’s attempts to counter GPS jamming using the GLONASS system, it experienced reduced accuracy, suggesting limitations in bypassing jamming techniques.
