This error has caused problems in prediction files, tracking, and data records. The NORAD and COSPAR IDs for GLONASS-120 and -121 where incorrect. The correct numbering is as follows: Western Russian =20 GLONASS GLONASS Kosmos COSPAR COSPAR NORAD Orbit = Freq. Number Number Number ID ID SIC Number Plane = Channel Slot ----------- ------- ------ --------- ------- ---- ------ ------ = ------- ------ GLONASS-119 731 2459 2010-007A 1000701 9119 36400 3 = -3 22 GLONASS-120 732 2460 2010-007C 1000703 9120 36402 3 = 03 23 GLONASS-121 735 2461 2010-007B 1000702 9121 36401 3 = 02 24 CODE will begin providing prediction files using the correct numbering today; older data will be corrected in the next day or two and will be replaced in the archives shortly thereafter. Please update your station files as soon as possible with the=20 appropriate numbers so that all new GLONASS-120 tracking data=20 will be accounted for correctly. We regret the problems this=20 confusion has caused.
