Narrative:

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.
