On Wed., Oct. 11, top officials from NOAA and NASA will preview the upcoming launch and mission of the Joint Polar Satellite System, JPSS-1, the first in a series of four advanced NOAA polar-orbiting satellites that will help improve the accuracy of weather forecasts out to seven days. The Launch Configuration Electromagnetic Interference (EMI) measures the electromagnetic emissions and subjects it to expected electromagnetic radiation that the satellite would experience at the launch site.

JPSS-1 is the first in NOAA's series of four, next-generation operational environmental satellites created to circle the Earth in a polar orbit. "The Flight 2 development, build and test have proceeded smoothly and follow the success of the Flight 1 instrument for NPOESS Preparatory Project". As it works, JPSS-1 will gather measurements of atmospheric, terrestrial and oceanic conditions, including sea and land surface temperatures, vegetation, clouds, rainfall, snow and ice cover, fire locations, atmospheric temperature, water vapor and ozone. It was created to be the functional equivalent follow-on to the Advanced Microwave Sounder Units with improved sampling and coverage.

Northrop Grumman is a leading global security company providing innovative systems, products and solutions in aerospace, electronics, information systems and technical services to government and commercial customers worldwide. The data can be used to better predict weather events and hazards, such as a hurricane's track and a hurricane's intensity. Once it's operational, it will be renamed NOAA-20.


According to Space.com, JPSS-1 is meant to build off the work of other NOAA satellites. Instruments aboard polar-orbiting satellites, like ones aboard JPSS-1 and its preceding spacecraft, known as the Suomi-NPP, obtain data on the winds and moisture in the upper atmosphere. This interagency effort (JPSS) is the latest generation of USA polar-orbiting, non-geosynchronous environmental satellites.

The launch is planned for Wednesday, Nov. 15, 2017, from Space Launch Complex-2 (SLC-2) at Vandenberg Air Force Base, California.
