The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting. [1]
The satellite has a mass of 1297 kg, including 269 kg of propellant and 264 kg payload. It is designed for a minimum lifetime of 2 years. Scientific data are stored on a digital recorder with a capacity of 1.3 gigabits and transmitted at a rate between 56 and 512 kb. Polar is the twin satellite of Wind.
Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites. [2] The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commonly choose a Sun-synchronous orbit, where each successive orbital pass occurs at the same local time of ...

This visualization illustrates how JPSS-1 (now NOAA-20) orbit phasing and raising works relative to Suomi NPP, the notional way can be maneuvered a quarter-orbit along-track separation from NOAA-20 prior to launch of NOAA-21 (JPSS-2), and how a three-satellite constellation operates on a Sun-synchronous orbit node-crossing including sensor-swath footprints as the world turns below.
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits , a service that was, until the advent of the PSLV in 1993, only ...
This was the first developmental flight of the PSLV-D1. [1] The IRS-1E satellite which was proposed to be launched was derived from the engineering model of IRS-1A incorporating a similar camera and an additional German-built monocular electro-optical stereo scanner.
PSLV-C5 was the fifth operational launch and overall eighth mission of the Polar Satellite Launch Vehicle program. This launch was also the fifty-second launch by the Indian Space Research Organisation (IRSO) since its first mission on 1 January 1962.
