Potential GPS Interruptions

Mountain Home Air Force Base

2 September 2021

 From September 7 - 12, Mountain Home Air Force Base will be conducting training South-southeast of Bruneau in the vicinity of Saylor Creek Range. It is possible that devices in that area which rely on GPS may experience intermittent interruptions in signal between 10:00 a.m. and 8:00 p.m. during these dates. Those who have GPS enabled agricultural equipment or other devices that rely on GPS may be impacted during this time. We will also work with the Idaho Farm Bureau to disseminate this information.

 The impact of GPS interruptions will not be the same as previous training exercises. We are making every effort to limit the effects of the GPS reliability testing by using narrow and directionally-focused beam that will be targeted at specific aircraft. The equipment being used for the reliability testing will be positioned on the West side of Saylor Creek Range and will be directed West and Southwest. Natural backstops should make these effects unnoticeable to any GPS devices North and/or East of the dedicated area.

 We thank you for your patience and understanding as we undertake a critical training mission to ensure our readiness for national defense! This training ensures that we are prepared for real-world combat and remain lethal and agile. If you have any questions, please contact the Mountain Home AFB Public Affairs office at: (208) 828-6800 or email us at: 366FW.PA.Public.Affairs@us.af.mil.
