Civil Global Positioning System Service Interface Committee: Future Leap Second Scheduled
This added second to our GPS clocks is certain to be of assistance when you are trying to reach that next bridge opening! LOL! Isn’t technology amazing?
Yesterday, 18 July, the Air Force entered, into the GPS MCS, a Future Leap Second to become effective on 31 December 2016. As Navigation Uploads are/were performed over the following ~24 hours, GPS satellites will, one at a time, begin broadcasting this Future Leap Second, along with its date of effectivity and the Current Leap Second count, in accordance with IS-GPS-200. When specific satellites will begin broadcasting the new information will depend on the contact schedule over the next ~24 hours, which is dynamic and subject to real-time operations. When specific users will begin seeing the new information will depend on a number of factors, including satellite visibility and user equipment design.
