Federal investigators report that military GPS jamming interfered with the navigation system of a small medical plane before it crashed into a mountainside in New Mexico last month. According to the reports, the aircraft’s GPS system malfunctioned during the period when jamming occurred in the area. Investigators say pilots had been warned in advance to expect GPS interference because of the jamming. The accounts describe the crash as occurring after the plane’s GPS failed to function correctly while the military was transmitting jamming signals that disrupted GPS reception over the region. The reporting is based on investigator findings released after the crash and focuses on the link between the jamming activity and the GPS disruption. None of the provided sources dispute that the jamming was present, that it affected GPS performance, or that the pilots received prior notice regarding the possibility of GPS interference. The details available from these summaries do not change the broader timeline of the incident: last month’s crash, concurrent regional jamming, and subsequent investigation into the factors affecting the aircraft’s navigation.
