I used a program called ALM2TLE from http://www.geocities.com/kiwi_36_nz/alm2tle/alm2tle.htm to convert the Yuma almanac data from http://www.navcen.uscg.gov/gps/almanacs.htm I used the data in the 327.ALM file http://www.navcen.uscg.gov/ftp/GPS/archives/yuma/327.ALM And got the following for PRN 2 = NAVSTAR 56 (USA 180) GPS PRN=02 1 00002U 00 0 0 04329.69758772 .00000000 00000-0 00000-0 0 0004 2 00002 54.8641 285.1031 0115895 107.9364 47.3126 2.01378381 00007 So while it's active, it's not at the typical mean motion for gps satellites. So to me it still drifting. Here's the results I got with PRN 24=NAVSTAR 23 (USA 71), using the data in http://www.navcen.uscg.gov/ftp/GPS/archives/yuma/324.ALM GPS PRN=24 1 00024U 00 0 0 04326.71092105 .00000000 00000-0 00000-0 0 0009 2 00024 55.4313 288.0119 0095448 282.5282 261.8924 2.00562181 00004 Compared to the tle from the oig PRN 24 1 21552U 91047A 04326.95263297 -.00000067 00000-0 00000+0 0 3407 2 21552 55.4331 288.0311 0097502 282.1137 76.7751 2.00556755 98047 So it good enough to tell where it approx is.
