IKONOS-2 was an Earth-imaging satellite of DigitalGlobe Inc. which launched in 1999 and ceased operations in 2015.
It is part of ESA's Third Party Missions Programme, in which ESA has an agreement with DigitalGlobe to distribute data products from the mission.
|Date of launch||24 September 1999|
|Status||Decomissioned in March 2015|
|Orbit Height||681-709 km|
|Orbit Type||Sun-synchronous near-polar|
|Repeat Cycle||14 days|
At the time of its launch, IKONOS-2 brought imagery rivalling that of military satellites to the commercial market.
Its objectives were to provide this grade of material to non-military users.
Optical Sensor Assembly (OSA)
OSA had a primary mirror aperture of 70 cm and a folded optical focal length of 10 m using five mirrors. 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 3,375 pixels along-track. Its nadir image swath was 11.3 km.

|Spectral range MS (µm)||0.45-0.53, (blue)|
|Spatial resolution||1 m PAN (0.82 m at nadir),|
4 m MS (3.2 m at nadir)
|Pixel quantization||11 bit|
|Off-nadir pointing angle||±30° in any direction|
|Swath width (single image)|
|11.3 km x 11.3 km|
11 km x 100 km (length)
|Field of regard (FOR)||±350 km at 1 m GSD|
