During cruise flight at approximately XA:05; flight crew noted AHRS 1& 2 fault. The reason for the fault was loss of GPS due to military GPS signal jamming. Crew notified ATC and asked for a new clearance; ATC immediately responded with vectors to the next fix. Crew immediately tuned and identified raw-data (ground-based) NAVAIDs for situational awareness. Signal was improved by XA:36; and all systems were normal at XA:43. At this time; the crew notified ATC and resumed GPS navigation.Although there was no negative outcome from this event; perhaps more inclusive language in the GPS NOTAM would be helpful. Crew reviewed NOTAMs and noted that the Phenom 300 was specifically mentioned.
Embraer Phenom 100 Captain reported the complete loss of GPS signal near BAM VOR which he attributed to military activity in the area. He requested assistance from ATC until reliable navigation aids were established.
