- 001d8e8c-e9b1-4418-9941-f41321c2c500 definition "WV110 was designed and developed at ITT Corporation's Space Systems Division of Rochester, NY. The objective of the WV110 instrument is to provide high-resolution panchromatic as well as 8-band multispectral imagery for enhanced mapping and monitoring applications (including stereo imagery due to rapid retargeting capability). In September 2008, BATC started with the integration of the WV110 camera. On Feb. 24, 2009 the WV110 camera had been integrated into the WorldView-2 spacecraft and system-level testing has commenced. Imager type Pushbroom imager (or a line scan imaging system) Imaging mode Panchromatic (Pan) Multispectral (MS) 8 bands (4 standard + 4 additional colors) Spectral range 450-800 nm 400-450 nm (coastal blue) 450-510 nm (blue) 510-580 nm (green) 585-625 nm (yellow) 630-690 nm (red) 705-745 nm (red edge) 770-895 nm (NIR1) 860-1040 nm (NIR2) Spatial resolution at nadir 0.46 m GSD (0.52 m at 20º off-nadir) 1.8 m GSD (2.4 m at 20º off-nadir) Swath width 16.4 km (multiple adjoining paths can be imaged in a target area in a single orbit pass due to S/C agility) Detectors Pan: Si CCD array (8 µm pixel size) with a row of > 35,000 detectors MS: Si CCD 4 arrays (32 µm pixel size) with a row of > 9,300 detectors Data quantization 11 bit Geolocation accuracy of imagery ≤ 3 m (using a GPS receiver, a gyroscope and a star tracker) without any GCP (Ground Control Points) Optics TMA telescope with an aperture diameter of 1.1 m, focal length = 13.3 m, f/12 TDI (Time Delay Integration) 6 selectable levels from 8 to 64 in Pan and MS FOV (Field of View) > 1.28º Instrument size 3 m tall Spectral band Center wavelength (nm) Minimum lower band edge (nm) Maximum upper band edge (nm) Pan (WorldView-1) imager 650 400 900 Pan (WorldView-2) imager 625 447 808 MS1 (NIR1) 831 765 901 MS2 (red) 659 630 690 MS3 (green) 546 506 586 MS4 (blue) 478 442 515 MS5 (red edge) 724 699 749 MS6 (yellow) 608 584 632 MS7 (coastal blue) 427 396 458 MS8 (NIR2) 908 856 1043 Parameter / Spacecraft QuickBird-2 (QB) WorldView-1 WorldView-2 Launch date Oct. 21, 2001 Sept. 18. 2007 Oct. 08, 2009 Orbital altitude (SSO) 450 km 450 km 770 km Spacecraft mass at launch 931 kg 2500 kg 2800 kg Spacecraft bus size 3 m x 1.6 m Ø 3.6 m x 2.5 m Ø 4.3 m x 2.5 m Ø Spacecraft bus type BCP-2000 BCP-5000 BCP-5000 Solar array span 5.2 m 7.1 m 7.1 m Spacecraft power 1.14 kW (EOL) single junction GaAs cells 3.2 kW (EOL) triple junction GaAs cells 3.2 kW (EOL) triple junction GaAs cells Battery 40 Ah NiH2 100 Ah NiH2 100 Ah NiH2 Attitude actuation Reaction wheels CMG assembly CMG assembly S/C body pointing capability ±30º (nominal in any direction) ±40º (nominal in any direction) ±40º (nominal in any direction) Onboard propulsion 4 x 4.4 N hydrazine thrusters Yes Yes Spacecraft design life 5 years 7.25 years 7.25 years RF Wideband downlink 320 Mbit/s 800 Mbit/s 800 Mbit/s Onboard data storage 128 Gbit 2.2 Tbit 2.2 Tbit Payload (builder) BHRC60 (BATC) WV60 (ITT) WV110 (ITT) Telescope aperture 60 cm Ø 60 cm Ø 110 cm Ø Swath width 16.5 km 16.4 km 16.4 km Pan resolution at nadir 0.61 cm 50 cm 46 cm MS resolution at nadir 2.4 m - 1.8 m (8 bands) Monoscopic area coverage 1 x > 4 x > 4 x Single pass mono coverage 1 strip of 350 km 1 strip of 650 km 1 area of 60 km x 110 km 1 strip of 650 km 1 area of 96 km x 110 km Single pass stereo coverage Single scene (<10º off nadir track) 3 strip x 55 km 2 strip x 110 km 1 strip x 220 km 3 strip x 55 km 2 strip x 110 km 1 strip x 220 km" @default.
