Follow-On Mission FORMOSAT-3/COSMIC Mission

Mission

Establish an operational mission for near real-time numerical weather prediction 8,000 (threshold) profiles per day (the objective is 10,000)

Demonstration of near real-time numerical weather prediction 1,600~1,800 profiles per day

Spacecraft

NSPO will design, procure, and integrate 12 satellites at NSPO NSPO will integrate new GNSS P/L provided by JPL & perform P/L system Integration & Test at NSPO

NSPO define system requirement NSPO & Orbital design spacecraft ; UCAR provide P/L suite EDU and FM1 I&T at Orbital FM2 to FM6 I&T at NSPO

Follow-On Mission FORMOSAT-3/COSMIC Mission

Launch Vehicle

NOAA will provide 2 to 3 (TBR) launches into selected orbits / inclinations

Use the US Air Force MINOTAUR L/V through UCAR’s Acquisition

Ground

NOAA’s strategy to use US, Europe and Asia Ground Networks

Use USN ground stations for the first 2 years, and then supported by NOAA ground stations for the following 3~5 years

Operations

High degree of automated ground system for 12-satellite constellation

6-satellite constellation operations

Current Status and Near Term ActivitiesCurrent Status and Near Term Activities

Follow-On Program Proposal and FORMOSAT-7/COSMIC-2 Agreement have reached the final stage for formal approval and signature at NSC.

The Mission Feasibility Design Review at mission level is planned to be held in February.

NOAA is coordinating Level-1 requirement document and NSPO has been drafting mission requirement document. These two documents will become the baselines for the Follow-On mission. The Mission Definition Review is planned to be held in late March.

NSPO has been developing spacecraft straw- man design. The Mission System Requirement Review is planned to be held in late March.
