Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) is a program designed to provide advances in meteorology, ionospheric research, climatology, and space weather by using GPS satellites in conjunction with low Earth orbiting (LEO) satellites. The term "COSMIC" may refer to either the organization itself or the constellation of satellites (also known as FORMOSAT-3 in Taiwan). The constellation is a joint U.S.-Taiwanese project with major participants including the University Corporation for Atmospheric Research (UCAR), the National Science Foundation, the Naval Research Laboratory (NRL), the Air Force Research Laboratory (AFRL) on the U.S. side and the National Space Organization (NSPO) on the Taiwanese side.
The total cost of the project is US$100 million, 80% of which is being provided by NSPO, and the remainder by various U.S. agencies.[1]
After experiencing several delays, the launch of the COSMIC satellite constellation atop a Minotaur launch vehicle from Vandenberg AFB occurred at 01:40 GMT, on April 15 2006, despite heavy fog.[2] The satellites, which orbit at an altitude of 500 miles, will take over a year to move into the correct positions to provide full global coverage.

[edit] Instruments
The COSMIC satellites are be equipped with three primary forms of instrumentation for remote sensing, as follows:
- GPS Occultation Experiment
- Tri-band beacon (TBB)
- Tiny Ionospheric Photometer (TIP)

[edit] Deployment
All 6 microsatellites were launched on a single launch vehicle and deployed into a single parking orbit after launch. The spacecraft will then be deployed into separate orbital planes through the use of precession due to the oblateness of the Earth and raised to a final orbital altitude over the course of several months. Scientific data will be collected during the deployment process.
