After circling our planet for the last year or so in space, we are happy to announce that 40-cm high resolution satellite imagery from KOMPSAT-3A is now ready for commercial sales! If you are a regular user of Image Hunter, you might have already seen some KOMPSAT-3A in your archive searches as we added it in during July.
For those of you who have not heard of the new 40-centimeter (cm) panchromatic and 1.6-meter (m) 4-band multispectral (i.e. blue, green, red and near-infrared) high-resolution satellite, KOMPSAT 3A, here are some of its key specifications:
- KOMPSAT-3A Launch Date: March 26, 2015, 22:08:45 UTC
- KOMPSAT-3A Sensor Resolution:
- Delivered at 40-cm (or 50-cm and 55-cm options) panchromatic & 1.6-meter (m) (or 2-m and 2.2-m options) multispectral
- Native resolution at nadir – 55-cm panchromatic & 2.2-m multispectral
- KOMPSAT-3A Revisit Frequency: (at 40° lat)
- 0.9 days (< 45° off-nadir)
- 2.7 days (< 20° off-nadir)
- KOMPSAT-3A Footprint Width: 13 km (at nadir)
- KOMPSAT-3A Georeferenced Horizontal Accuracy: 9.9-m CE90 (global average, depends on terrain)
KOMPSAT-3A extends the long tradition of the high-resolution KOMPSAT-2 and KOMPSAT 3 constellation, with a marked improvement in resolution and georeferenced accuracy.
