- NOAA 14 (National Oceanic & Atmospheric Administration) Weather Satellite: Objectives: To continue the Advanced TIROS-N program by working as a companion with NOAA-10, 11 and 12 in order to provide continuous coverage of the Earth and to provide high-resolution global meteorological data. NOAA-14 is the sixth operational satellite in the Advanced TIROS-N series (NOAA 13 never officially became operational as it failed during its 21 day checkout period). The satellite carried the AVHRR, TOVS, and the solar proton monitor. All of which were present on previous NOAA satellites. The ERBE instruments, the SBUV radiometer and the SARSAT systems were also flown on this satellite. NOAA-14 was placed in a near circular, (470nm) polar orbit. NOAA 14 replaced NOAA 11 whose cloud cover imaging instrument had failed a few months before this launch. Besides an imaging radiometer, it carries optical sounders to monitor temperature and moisture content in the atmosphere, and counters to measure energetic electrons and protons. A gas leak caused some difficulties in attitude control shortly after launch, but this has been resolved. The motor for the Microwave Sounding Unit on the NOAA 14 spacecraft has stopped working. Records show the unit is from a delivery made to Martin Marietta dating back to 1984! The microwave sounder returned to normal operation in May 1995 after a software patch was installed to cope with any repeat failure. Its life expectancy remains uncertain. In Feb 1995, the SARP failed, the SBUV/2 Cloud Cover Radiometer (CCR) failed, and DTR 4A/B was deemed inoperable.
