four bands
Landsat-TM has seven bands; IKONOS has four bands; hyperspectral sensors typically may have more than 200 very narrow bands (cf. Landsat’s seven bands). Radiometric resolution refers to the number of potential brightness values that can be stored for a pixel.
What is the sensor of IKONOS?
The IKONOS satellite sensor is a high-resolution satellite operated by MAXAR Technologies Inc. Its capabilities include capturing a 3.2m multispectral, Near-Infrared (NIR) 0.82m panchromatic resolution at nadir.
What is IKONOS in remote sensing?
Launched on September 24, 1999, IKONOS is the world’s first commercial satellite providing very high resolution (up to 1 m) imagery of the earth. IKONOS simultaneously collects one-meter resolution black-and-white (panchromatic) images and four-meter resolution color (multispectral) images.
How many sensors are there in IKONOS 2?
The detectors at the focal plane included a panchromatic sensor with 13,500 pixels cross-track, and four multispectral sensors (blue, green, red, and near-infrared) each with 3375 pixels along-track. Its nadir image swath was 11.3 km….Optical Sensor Assembly (OSA)

What kind of sensor does IKONOS use?
IKONOS Satellite Sensor (0.82m) The IKONOS satellite sensor is a high-resolution satellite operated by DigitalGlobe. Its capabilities include capturing a 3.2m multispectral, Near-Infrared (NIR) 0.82m panchromatic resolution at nadir.
What is the Ikonos satellite?
The IKONOS satellite is the world’s first commercial satellite to collect panchromatic (black-and-white) images with 0,80 m resolution and multispectral imagery with 3,2-meter resolution. The satellite itself was launched on the 24th of September in 1999 from the Vandenberg Air Base, California.
What was the design life of the IKONOS?
Its design life was seven years. IKONOS operated in a Sun-synchronous, near-polar, circular orbit at approximately 680 km (423 mi). IKONOS ‘s primary instrument was the Optical Sensor Assembly (OSA), designed and built by Kodak. It had a primary mirror aperture of 70 cm (28 in), and a folded optical focal length of 10 m (394 in) using 5 mirrors.
Is IKONOS owned by GeoEye?
