Additionally, occasional CSactions to manage clock offsets may also inhibit the ability toprovide specified almanac time parameter accuracies.”Project Officer <strong>Resolution</strong>: Reject.While the information is useful, it does notbelong in this document. Should becaptured as a probability of occurrence ifincluded at all.Concurrence:Rationale: Clarification of reality. As one example, after weperform a necessary, periodic timing adjustment on a satellite,it can and will take literally hours [empirically, on averageabout 24 hours], before we will have uploaded the entireconstellation with new almanac time parameters reflecting thetiming adjustment. Additionally, user sets that downloadalmanacs based on the time of applicability (tOA), can andwill experience the elapsing of additional hours [empirically,as much as 24 hours], before such user equipment willrecognize the update.20 Mar 08
