DigitalGlobe Chronology


1997 December 24 - . 13:32 GMT - . Launch Site: Svobodniy. Launch Complex: Svobodniy LC5. LV Family: Topol. Launch Vehicle: Start-1.
  • Early Bird - . Payload: EarlyBird. Nation: USA. Agency: DigitalGlobe. Manufacturer: McLean. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft: Early Bird. Decay Date: 2000-07-27 . USAF Sat Cat: 25123 . COSPAR: 1997-085A. Apogee: 488 km (303 mi). Perigee: 479 km (297 mi). Inclination: 97.3000 deg. Period: 94.10 min.

2000 November 20 - . Launch Site: Plesetsk. Launch Complex: Plesetsk LC132/1. LV Family: Kosmos 3. Launch Vehicle: Kosmos 11K65M. LV Configuration: Kosmos 11K65M 47165-631. FAILURE: Second stage failed to restart at apogee.. Failed Stage: 2.
  • QuickBird 1 - . Mass: 950 kg (2,090 lb). Nation: USA. Agency: DigitalGlobe. Manufacturer: Ball. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft: Early Bird. Decay Date: 2000-11-21 . USAF Sat Cat: 26617 . COSPAR: 2000-074A. Apogee: 614 km (381 mi). Perigee: 80 km (49 mi). Inclination: 65.7000 deg. Period: 91.49 min. The Kosmos-3M second stage entered an 81 x 614 km x 65.8 deg orbit but failed to restart at apogee, and reentered at the next perigee over Uruguay. The loss of the QuickBird 1 satellite was a heavy blow to EarthWatch Inc. QuickBird1 was a 1-m resolution commerical imaging satellite using a Ball Aerospace BCP-2000 bus. Their earlier satellite, EarlyBird, failed after a few days in orbit in December 1997. EarthWatch's rival, SpaceImaging, lost one satellite as well but its second Ikonos was operating in orbit.

2001 October 18 - . 18:51 GMT - . Launch Site: Vandenberg. Launch Complex: Vandenberg SLC2W. LV Family: Delta. Launch Vehicle: Delta 7320-10. LV Configuration: Delta 7320-10 D288.
  • QuickBird - . Payload: QuickBird 2. Mass: 980 kg (2,160 lb). Nation: USA. Agency: DigitalGlobe. Manufacturer: Ball. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft: QuickBird. USAF Sat Cat: 26953 . COSPAR: 2001-047A. Apogee: 471 km (292 mi). Perigee: 471 km (292 mi). Inclination: 97.2000 deg. Period: 94.00 min. The QuickBird commercial imaging satellite was owned by DigitalGlobe (formerly EarthWatch) and used a Ball BCP2000 bus with a launch mass of 1028 kg and a dry mass of about 995 kg. The Delta upper stage entered a 185 x 472 km x 98.1 deg orbit at 1902 GMT. At 1948 GMT it reached apogee and fired again to deploy QuickBird into a 461 x 465 km x 97.2 deg orbit. The Delta then made a series of unusual depletion burns, lowering its perigee to 167 km and changing inclination to 108.9 deg.

    Quickbird 2 was to be operational after a few months of calibration and "ground-truth" checkouts to market high resolution images. The 1.0 tonne satellite was reported to be capable of images with a resolution as small as 0.6 meter, though the standard products were to be coarser. Unlike the comparable quality images from IKONOS images, some of which are currently marketed exclusively to the US military, all Quickbird 2 images may be available in the open market.
