USAF to test increased GPS signal power Jan. 25

January 24, 2017  - By

Beginning Wednesday, Jan. 25, Air Force Space Command (AFSPC) will conduct a limited-duration test implementing an increase of the Ll C/A power level on the GPS Block IIR-M and llF satellites — a total of 19 satellites.

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.

“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,” said Gen. John W. Raymond, U. S. Air Force (USAF) commander, in a “Memorandum for Distribution.”

Military users can contact the GPS Operations Center at DSN 560-2541, while civilian users can contact the U.S. Coast Guard Navigation Center at 703-313-5900. In the event of unexpected critical impacts, a process to cease testing operations has been put in place.

The AFSPC point of contact for this test is Maj. Jeffrey Koch, DSN 692-0233, commercial 719-554-0233.
