4/16/19 - We began working again the morning of the 16th to resolve the lingering issue. After setting up our GPS equipment the number of satellites began to drop until eventually our equipment was not tracking any satellites. We are in the vicinity of an aiport and an Air Force base. Prior to this incident we were using a different frequency equipment which we found was supposed to have issues with the frequencies being used at the AFB/Aiport. We changed our equipment to run on 900 mhz frequency to avoid any interference and the equipment was running as it should. Then we began having issues as listed above. We have had a certified troubleshooter of equipment on site and they are in agreement that there is some type of interference or jamming occurring.

NAVCEN: The U.S. Air Force points to Interface Specification IS-GPS-200, paragraph 20.3.3.5.2.2, Almanac Reference Time, which states: "The almanac reference time, t(oa), is some some multiple of 2(12) seconds occurring approximately 70 hours after the first valid transmission time for this almanac data set (reference 20.3.4.5). The almanac is updated often enough to ensure that GPS time, t, shall differ from t(oa) by less than 3.5 days during the transmission period." They go on to point out "For this reason, beginning late on JDay 094 [April 4th], the GPS constellation began, one satellite at a time, broadcasting almanacs with almanac reference times which, when un-truncated as necessary, translate(d) to a calendar date of 7 April 2019 (after the associated 1024-week rollover), correctly, and IAW IS-GPS-200."

NAVCEN: The GPS Operations Center reviewed the GPS Constellation and Control Segment and determined it to be healthy, stable and robust during that time. It continues to provide precise positioning navigation and timing information to military and civilian users around the world.
NANU in question were sent as a precautionary measure. Information that was received from these satellites was still accurate.
NAVCEN: The GPS Operations Center provided the following response: In reference to your question, no maintenance activities were initiated prior to the SVs being set UNHEALTHY. Moving forward, the GPS Master Control Station will work to ensure the NANU more closely tracks the exact time the SVs are set UNHEALTHY to avoid misconceptions. Again, thank you for bringing this matter to our attention.
NAVCEN: PRN4 is being used to test SVN36. This testing was published in NANU 2018042. "ON APPROXIMATELY 10 OCT 2018 SVN36 WILL RESUME TRANSMITTING L-BAND UTILIZING PRN04. AT L-BAND ACTIVATION, SVN36/PRN04 WILL BE UNUSABLE UNTIL FURTHER NOTICE. ADDITIONALLY, NO BROADCAST ALMANACS WILL INCLUDE SVN36/PRN04 UNTIL FURTHER NOTICE."

NAVCEN: Equipment alarm records provided by the reporting source indicate similar errors across several timing units used by the reporting source and appear to be typical for this equipment. Errors were momentary (less than one second) with an average of approximately 90 momentary errors per site over the course of a year. Some equipment initiated more alarms, but there seemed to be no correlation between times, locations, or types of alarms. Redundant antenna and receiver systems did not alarm at the same time. The reporting source contacted their equipment manufacturer who identified a firmware issue. Reporting source now believes the problems are equipment issues and will provide more information if it becomes available.

NAVCEN: There is no activity in the GPS constellation of satellites that could be causing the problem indicated. GPS equipment is not assigned a specific satellite. Rather the equipment will track all satellites in view, usually 8-12 of them depending on location. However, given this type of date time problem and the subsequent failure of your equipment, there is a high probability that your equipment was affected by the 2019 GPS rollover event. If your equipment is showing a date other than todays date, this is a problem with how your equipment is handling the updated GPS week number value. We recommend you ensure your equipment software is up to date, refer to your equipment manual, update your application, or contact your application developer or equipment manufacturer for assistance. We recommend all users share these reports with their application developer or equipment manufacturer. This real world feedback can help developers and manufacturers improve their products.

NAVCEN: We have contacted the GPS Operations Center and they have informed us that: “After a recent ground system software update, we received reports of some users experiencing negative issues. As a result, we re-verified that our software update was indeed in complete compliance with IS-GPS-200 standards. Nonetheless, in order to continue to support all of our users to the maximum extent possible, we rolled back the software update to a previous version so that we can take the time to consult with the affected receiver manufacturer and proceed forward in a way to ensure dependable access to GPS for all users. In this case, as always, Air Force officials continue to work with their counterparts in the U.S. Coast Guard to analyze and respond to all user concerns.”

NAVCEN: 5 January 2017 the Civil GPS Service Interface Committee Executive Secretariat release the following message: Beginning 25 January 2017, Air Force Space Command (AFSPC) will conduct a limited duration test implementing an increase of the L1 C/A power level on the GPS Block IIR-M and IIF satellites (19 vehicles). The C/A power will remain within IS-GPS-200-H specifications and the power increase is not expected to increase the noise floor by more than 0.3 signal-to-noise ratio in the worst case. AFSPC reports, "We assess that there will be no adverse impacts to civil, commercial or military GPS users, but anyone who experiences issues during this test should address them through established reporting channels." Civil, non-aviation, GPS users should contact the U.S. Coast Guard Navigation Center at 703-313-5900 or online at http://www.navcen.uscg.gov/?pageName=gpsUserInput. Civil aviation GPS users should contact the FAA and file a report at https://www.faa.gov/air_traffic/nas/gps_reports/. All other nonoperational concerns or inquiries regarding this test should be directed to Air Force Space Command at a3sm.wf@us.af.mil.
