Based on its past behaviour, an orbit-raising manoeuvre can be expected before its mean motion reaches 14.84 rev/d, sometime before day 105.4 (14 April), at the present rate of decay. My records show only one case of previous operational satellites in this series for which the mean motion was permitted to go higher than 14.84 rev/d. In 1995, on day 233, both 88099A and 92083A reached mean motions in excess of 14.846 rev/d, and then manoeuvred a day or two later. If USA 129's mean motion is permitted to go as high this time, then the manoeuvre could be as late as day 111.5 (20 April), at the present rate of decay.
