NOAA-18 Spacecraft Status Summary


Spacecraft Letter:   N International Designation:   2005018A
Catalog Number:   28654 Launch Date:   05/20/2005
Operational Date:   8/30/2005 Operational Status:  PM Secondary
GAC:   Yes HRPT:   Yes   STX-3/HSB   1707.0 MHz
LAC:   No APT:   Yes   VTX-2   137.9125 MHz
LTAN:   17:40:01 Inclination Angle:  98.74 deg
