Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) is a program designed to provide advances in

National Space Organization
(NSPO) on the Taiwanese side.

The total cost of the spacecraft and launch was US$100 million, 80% of which was 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

Vandenberg AFB occurred at 01:40 GMT, on 15 April 2006, despite heavy fog.[2]
The satellites, which orbit at an altitude of 500 miles, required over a year to move into the correct positions to provide full global coverage.

A follow-up constellation, COSMIC-2, launched 25 June 2019 on a Falcon Heavy rocket.

Instruments

Components of a FORMOSAT-3 satellite

The COSMIC satellites are equipped with three primary forms of instrumentation for remote sensing, including:

Deployment

All 6

oblateness
of the Earth and raised to a final orbital altitude over the course of several months. Scientific data were collected during the deployment process, along with experimental validation and calibration.

Status

Model of FORMOSAT-3

FM2's power system lost 50% of its output in February 2007, while FM3's solar panel also malfunctioned since August 2007. As a result, both satellites are operating in a degraded state, capable of returning data only during specific solar angles. FM6 went out of control in September 2007, but control was restored by 16 November of the same year.[4][5] FM3 had severe power problems since 6 July 2010. It was declared not functional since then. FM4, FM5, and FM6 have had battery aging problem.[6]

The data published by the COSMIC-1 constellation has been used in

weather models to improve the quality of weather forecasts.[7] On 1 May 2020, the satellite constellation was retired.[8]
