My orbital analysis revealed that I had reduced the wrong stars for my final three obs of 07027C of July 14 UTC. Also, I mistakenly omitted my first obs of 07027C of Jul 15 UTC, and included a duplicate of my 3rd obs. The following are the correct data for both 07027A and C: 31701 07 027A 2701 G 20070714081148560 17 25 0043291-175507 37 S 31708 07 027C 2701 G 20070714081309810 17 25 0042112-173846 28 S 31708 07 027C 2701 G 20070714081318870 17 25 0045973-163847 77 S 31708 07 027C 2701 G 20070714081442810 17 25 0130754-054286 28 S 31708 07 027C 2701 G 20070714081501270 17 25 0141637-030781 96 S 31701 07 027A 2701 G 20070715085105880 17 25 0016038+080756 18 S 31708 07 027C 2701 G 20070715085257850 17 25 0012558+090210 18 S 31708 07 027C 2701 G 20070715085325330 17 25 0036719+151501 57 S 31708 07 027C 2701 G 20070715085454850 17 25 0217166+340438 18 S Here are updated elements: NOSS 3-4 (A) 0.0 0.0 0.0 4.9 v 843 X 1186 km 1 31701U 07027A 07196.35974419 .00000020 00000-0 20000-4 0 04 2 31701 63.3811 327.1319 0231996 149.9377 211.5215 13.65511037 01 Arc 2007 Jul 12.36 - 15.37, WRMS residuals = 0.020 deg NOSS 3-4 (C) 0.0 0.0 0.0 4.9 v 850 X 1183 km 1 31708U 07027C 07196.36099867 .00000019 00000-0 20000-4 0 05 2 31708 63.3645 327.1105 0225346 150.5490 210.8466 13.65058100 09 Arc 2007 Jul 14.34 - 15.37, WRMS residuals = 0.013 deg These elements are based on short arcs and not many points, so they are likely to vary a bit as the observational arc grows. Manoeuvres to-date: 1. Within about one day of 2007 Jun 24 UTC, 07027A and C raised their mean altitude by 0.63 km and 0.38 km, respectively, resulting in station-keeping, with C trailing A by about 35 s. 2. On July 12, near 17:00 UTC, 07027C raised its mean altitude by 1.6 km. Both objects remain more than 89 km below their nominal operational mean orbital altitude, of about 1106 km (initial orbit typically is elliptical, about 1006 x 1206 km). Argument of perigee remains about 30 deg lower than nominal, and inclination is about 0.05 deg lower than nominal.
