What This Article Covers

1.Over 1,650 vessels experienced GPS/AIS interference in West Asia on March 7, 2026, a 55% weekly increase, amid the US-Iran war.

2.GPS spoofing (providing false location) is more dangerous than jamming (blocking signal), risking collisions and navigation errors in vital sea lanes.

3.India's NavIC system and alternative navigation aids like INS and GBNAs are crucial for mitigating such electronic warfare threats, especially in border regions.
