Northrop Grumman reports it has completed the engineering testbed prototype of the National Polar-orbiting Operational Environment Satellite System (NPOESS), which will give civilian and defense users extremely accurate data on weather conditions as orbits the Earth once every 100 minutes. NPOESS data will aid mission planners in forecasting conditions in an operation area to take maximum advantage of the weather.
NG says that they’ve reached the Electrical Engineering Model Test Bed milestone early. “This test bed marks NPOESS’ transition to the final phase of spacecraft development,” said Dave Vandervoet, vice president and NPOESS program manager for Northrop Grumman’s Aerospace Systems sector. “We completed the EEMTB early, ahead of spacecraft integration and test, giving us ample opportunity to find and fix problems to ensure successful satellite integration and test. The spacecraft is now at a higher level of maturity for integration and test than is typical at this stage.”
