The FORMOSAT-2 Advantage

Daily Revisits
When still active in space, FORMOSAT-2 offered daily revisits of any location along its the orbital track. However, there is lack of archive coverage outside these orbits.

Great Clarity
For 2-meter pansharpened resolution, the clarity of features not normally seen in medium resolution imagery (such as airplanes and construction equipment) is stunning.

Monitoring & Mapping
When still active in space, FORMOSAT-2 offered large area coverage, daily revisits and superb clarity. It was an excellent choice for site monitoring, disaster management and relief and regional mapping.

Overview & HistoryFORMOSAT-2 SpecificationsPricing

Launched on May 21, 2004 from Vandenberg Air Force Base, CA by the National Space Organization (NSPO), FORMOSAT-2 is the first medium resolution satellite developed by the Taiwanese. FORMOSAT-2 featured optical sensors with 2-meter (m) panchromatic and 8-m multispectral (i.e. blue, green, red and near-infrared/NIR) resolution. With an orbital height of 891 kilometers (km), FORMOSAT-2 offered daily revisits over any location within its fixed orbital track.

FORMOSAT-2 collected its last image on June 20, 2016 and was decommissioned shortly thereafter on August 1, 2016.
