satellites. The first polar-orbiting weather satellite launched as part of the POES constellation was the Television Infrared Observation Satellite-N ( TIROS-N), which was launched on 13 October 1978. The final spacecraft, NOAA-19 (NOAA-N Prime), was launched on 6 February 2009. The ESA-provided MetOp satellite operated by EUMETSAT utilize POES-heritage instruments for the purpose of data continuity. The Joint Polar Satellite System (JPSS-1, now NOAA-20), which was launched on 18 November 2017, is the successor to the POES Program. On-orbit satellite operations of POES is performed by NOAA's Office of Satellite and Product Operations (OSPO).

s do not repeat on a daily basis. The systems includes both morning and afternoon satellites which provide global coverage four times daily.

Applications

Data from the POES support a broad range of environmental monitoring applications including weather analysis and forecasting, climate research and prediction, global sea surface temperature measurements, atmospheric soundings of temperature and humidity, ocean dynamics research, volcanic eruption monitoring, forest fire detection, global vegetation analysis, search and rescue, and many other applications. One of the key instruments of the current POES system is the High Resolution Infrared Radiation Sounder (HIRS/4). HIRS/4 senses within 20 channels ranging from visible bands to long wave infrared (0.69-14.96 micron wavelengths), to sense variation of temperature, humidity, and pressures within the atmosphere. The data collected from HIRS/4 is collaboratively used with the Advanced Microwave Sounding Unit (AMSU) to advance research in sea surface temperatures, cloud coverage analysis, ozone concentrations throughout the atmosphere and earth's radiance.

is the international humanitarian Search and Rescue Satellite-Aided Tracking System that is responsible for alerting and locating information to search and rescue authorities. COSPAS-SARSAT satellites detect 406 MHz distress signals at all times from nearly any place on the globe. Each 406 MHz beacon has a unique fifteen digit identification (ID) code embedded within its signal which allows rescuers to have an identification of the party in distress before they head out on the rescue.
