US researchers have reported the first-ever observation of short-term GPS interference, potentially linked to Russian satellites. The interference lasted up to 10 seconds on the frequency 1575.42 MHz.
Russian satellites, particularly those in the Edinaya Kosmicheskaya Sistema (EKS) constellation, have been identified as the source of mysterious, seconds-long GPS interference bursts across Europe, sparking concerns over potential intentional jamming capabilities.
NASA's CYGNSS and NISAR satellites, designed for cyclone and ice sheet monitoring, have identified a GPS jammer in Iran within several kilometers, potentially helping mitigate navigation risks for aircraft and ships amid rising GPS interference globally.
