The newest JPSS satellite tv for pcnow often known as NOAA-20, launched in November 2017. Previous to that, the NOAA-NASA Suomi Nationwide Polar Orbiting Partnership (Suomi-NPP), which offered the blueprint for JPSS, launched in 2011.
The satellites rotate from pole to pole, observing the whole floor of the Earth twice a day. It passes 512 miles (824 kilometers) above Earth at a velocity of 17,000 mph (27,360 km/h) and crosses the equator 14 occasions a day. And so they all carry the VIIRS instrument.
