The KOMPSAT-3 Advantage

50-cm Zoom Processing
Through SI Imaging proprietary Zoom processing, 50-cm panchromatic and 2-m 4-band multispectral products are now available.

14-bit Depth
With industry leading bit depth, KOMPSAT-3’s sensors are more sensitive to small changes in surface reflectance. This is crucial for accurate spectral analysis.

Afternoon Collections
KOMPSAT-3 is the only multispectral satellite to collect imagery in the afternoon. This can be important for agricultural studies as chlorophyll concentrations vary throughout the day.

Cloudy Area Tasking
In some area, skies tend to be clearer in the afternoon, for instance over tropical islands. For these locations, KOMPSAT-3 is the choice for a new collection.

An Older Sibling, KOMPSAT-2
Launched on July 28, 2006, KOMPSAT-2 features 1-m panchromatic and 4-m 4-band multispectral imagery. Ask your Apollo Mapping sales representative for pricing and coverage details!
Overview & HistoryKOMPSAT-3 SpecificationsPricing

Launched from Japan’s Tanegashima Space Center on May 17, 2012, KOMPSAT-3 is the first sub-meter optical satellite developed and operated by the Korea Aerospace Research Institute (KARI). Orbiting our planet at 685 kilometers (km), KOMPSAT-3 collects 70-centimeter (cm) panchromatic and 2.8-meter (m) 4-band multispectral (i.e. blue, green, red and near-infrared/NIR) imagery. Introduced in 2020, Zoom processing by SI Imaging enhances the sharpness of raw KOMPSAT 3 imagery to produce 50-cm panchromatic and 2-m 4-band multispectral products.

KOMPSAT-3 separates itself from other multispectral high-resolution satellites with afternoon collection times and 14-bit depth imagery. This makes the Korean satellite an excellent choice for agricultural studies as well as a compliment to imagery collected in the morning.
