Corporate jet Captain reported GPS jamming in ZBW airspace. The jamming began as another aircraft passed overhead and lasted approximately five minutes.

Narrative

We were cruising at FL410 (+/- XA21z) enroute to HYA - ZZZ. Aircraft Y was crossing our path (right to left at at 30*-40* angle at FL430) and just as he crossed directly overhead; the first of many CAS (Crew Alerting System) messages illuminated to include: in order of occurrence: White CAS= Turn Coordinator then AT FAIL; followed by many Amber CAS too many to remember; however I believe Avionics Fail then; GPS Both on 2 on lower left PFD (Primary Flight Display). I notified ATC of the event and asked if there were any other planes reporting GPS jamming event or if any anomalies from military. I was talking to Boston Center VHF. He stated we were the first to report such event; and they were not aware of any issues. I pulled up GPS POSITION DATA and #1 GPS was all blanks. The messages cleared and GPS #1 came back on-line within a few minutes; and we continued flight without incident / or deviation. I quickly selected HDG (Heading) MODE to prevent any issue with possible Spoofing and then re-selected NAV MODE and I asked the FO to hand fly plane during the event. He did a great job maintaining altitude; course; and airspeed. I did also report this to the next ATC frequency; and the supervisor on this freq. asked a few questions for information purposes. I also asked this supervisor if they could tell me if Aircraft Y was a military aircraft...wondering if this plane had caused the event...he could only tell me it was Aircraft Y; unsure of anything else.Suggestions: Event only lasted 3-5 mins; no altitude airspeed or route issues.Upon landing rollout; we did get multiple AT Hold FAIL Red CAS msgs...I pulled the CB (Circuit Breaker) to prevent re-occurrence once we were off the runway.We shut plane down at FBO. No CAS messages were noted on return flight to ZZZ1.
