As GPS outage and testing NOTAMs get larger and more frequent, it’s just one more risk all of us in civil aviation need to pay attention to and mitigate in our flight operations. The information below shows the number of healthy GPS satellites, since 1998. Because of this issue it's important to get pilots to record all comm frequencies in use in addition to their position and time when they experience an inflight GPS outage. [0]

U.S. Department of Transportation Federal Aviation Administration 800 Independence Avenue, SW Washington, DC 20591 1-866-TELL-FAA (1-866-835-5322) * Make/Model/ SW Rev. WAAS RNP. WAAS Satellite Status. outages operated by DWI • EURONOTAM ÆEGNOS Availability outages operated by ESSP • GISE combines the services: • GPS RAIM & EGNOS outage information available through AUGUR website and via NOTAM Proposals • G NSS I nformation S ervice for E urope ADS-B XML Service. Of course, one last way to mitigate this potential risk might just be to go VFR and have a more scenic flight at the same time! The FAA developed the Wide Area Augmentation System (WAAS) to improve the accuracy, integrity and availability of GPS signals ... Should an outage occur during the approach, reversion to LNAV minima or an alternate instrument approach procedure may be required. The number of satellites in the GPS constellation comes from the SEM almanac for that day. Outage Summaries available for 2020/06/15 09:01 - 2020/06/18 08:01 UTC. Real-Time WAAS and GPS Monitoring. Avionics: Outages Yes, Click to View. Check the GPS signal bars while transmitting a verbal count on each of those frequencies for at least 30 seconds to see if this is a problem with your comm radios. Service Availability Prediction Tool (SAPT) Getting Started with ADS-B.

e.g. Flight Information Entry Form. The number of unhealthy satellites for that day comes from the Satellite Outage File.
WAAS IGP Status. There was a cancelled, very large proposed GPS outage (NOTAM) centered on NAWS China Lake which specifically warned that the EMB-505 Phenom 300 business jet specifically should avoid operating in the Western US during this mysterious GPS outage/jamming test event. GPS and GLONASS use different frequencies. AOPA is working with the FAA to incorporate GPS outage graphics into its Notam Search system, and some flight planning providers are looking for ways to provide the graphics to their users as they do now with temporary flight restrictions. Somebody with a broadband jammer could interfere with both simultaneously, but if somebody were intending to test GPS jamming susceptibility they could do it without interfering with GLONASS or other users in L-band. WAAS LPV. The interference generated may make the GPS signal unreliable and the outage cone described by NOTAM lets you know that you can't trust the GPS signal during this time. SPS PDOP.

of GPS receiver used: * What was your altitude at the time of the anomaly ( MSL )? They're both L-band-ish, but don't occupy the same frequencies within the band. GPS Satellite Health Information.

This outage is due to department of defense GPS interference testing taking place 17-18 Nov 2015.
12500 MSL If contacted, what is the name of the Aviation facility you reported the GPS Anomaly to (ARTCC, TRACON, ATCT, FBO etc.)?
