FORMOSAT-2 for daily imaging of your areas of interest
Earth observation systems offer more or less broad coverage and ever-finer detail, but their revisit frequency is still limited for surveillance purposes. FORMOSAT-2, the first and only high-resolution satellite with a daily revisit capability, overcomes this obstacle to provide a new response to your surveillance needs.

Daily monitoring capability
The ability to acquire repeat imagery of an area of interest every day with the same sensor, from the same angle and under the same lighting conditions guarantees a timely flow of compatible data.

FORMOSAT-2's very specific orbit means it can acquire any scene in its coverage area every day (geosynchronous orbit) under the same lighting conditions (sun-synchronous orbit) and from the same angle. The satellite can also be tasked to cover a specific area and period of interest.

This combination of high resolution and daily revisits is unrivalled today in the civil high-resolution satellite market.

Unprecedented viewing features
Unlike other very-high-resolution satellites, FORMOSAT-2 guarantees the same viewing parameters every time, so you know how many images you will obtain and you can be sure they will register perfectly.

FORMOSAT-2’s local equator-crossing time is 9.30 a.m., where most optical satellites currently operating cross one hour later. This slightly earlier time, combined with daily revisits, increases the chances of acquiring useful imagery in equatorial regions where convective clouds form throughout the morning

Resolution for change detection
FORMOSAT-2’s spatial resolution — 2 metres in panchromatic (black and white) and 8 metres in multispectral (colour) mode — is an additional asset for surveillance. Ideally suited to strategic and operational intelligence missions, it is able to identify and characterize military sites, naval bases, air bases and refugee camps; perform reconnaissance of ships, aircraft and other assets; and surveillance of strategic or industrial facilities.

Blue band a plus
Like very-high-resolution satellites, FORMOSAT-2 has four bands: blue, green, red and near-infrared. Combined with the red and green bands, the blue band affords the ability to produce natural-colour composites without special processing. Used alone or with other channels, it also provides specific information for mapping shallow waters, distinguishing between bare earth and vegetation, mapping forests and identifying crops, and making atmospheric corrections.

A unique and effective response

FORMOSAT-2's unique advantages offer:

  • Guaranteed data acquisition: with the Priority option, the satellite can be tasked daily until it acquires the image you want, increasing the chances of obtaining imagery in unfavourable weather conditions.
  • Fast delivery: data are posted on an FTP site within 24 to 48 hours of acquisition, thus ensuring maximum currency of information.
  • Close tracking capability: imagery can be acquired daily or at regular intervals to keep track of fast-changing situations, providing a reliable revisit capability for your projects over the long term.
  • An ideal complement to submetric data: the combination of very-high-resolution archive imagery and FORMOSAT-2 multidate imagery provides a cost-effective monitoring solution.
  • A new coverage solution: FORMOSAT-2’s revisit frequency means you can quickly acquire coverage of your area of interest.

FORMOSAT-2 is a precious aid for defence and disaster management, as well as for mapping, agriculture, land planning and forestry.
