C/NOFS
Template:Infobox Spacecraft C/NOFS, or Communications/Navigation Outage Forecasting System is a satellite designed to investigate and forecast scintillations in the Earth's ionosphere. It was launched by an Orbital Sciences Corporation Pegasus-XL rocket at 16:55 GMT on 16 April 2008.
The satellite, which will be operated by the USAF STP, will allow the US military to predict the effects of ionospheric activity on signals from communication and navigation satellites, outages of which could potentially cause problems in battlefield situations.
C/NOFS has a three-axis stabalisation system, and is equipped with seven sensors. It will be placed into a low Earth orbit with orbital inclination of 12°. It carries the CINDI experiment for NASA. Launch was originally scheduled for 2003, but has been delayed due to a number of issues.
