WorldView-4
WorldView-4, previously known as GeoEye-2, was a third generation commercial Earth observation satellite launched on 11 November 2016, at 18:30:33 UTC. The spacecraft was operated by DigitalGlobe. With a maximum resolution of 31 cm (12 in), WorldView-4 provided similar imagery as WorldView-3, the highest resolution commercially available at the time of its launch.
The spacecraft suffered a failure in one of its control moment gyroscopes in January 2019, and operations were unable to be recovered. It reentered over New Zealand on 30 November 2021.
Work on GeoEye-2 began in October 2007 when commercial imagery company GeoEye selected ITT Corporation to begin work on long lead-time items for the satellite camera system. In March 2010, an initial contract for construction of the spacecraft was awarded to Lockheed Martin Space Systems, which previously built the Ikonos imaging satellite. At the time, GeoEye-2 was planned for launch in late 2012. The spacecraft's preliminary design review was completed in November 2010, while its critical design review (CDR) was completed in June 2011.
Lockheed Martin issued a contract to ITT Corporation in August 2010 to continue work on the camera system, and the company announced the completion of the system's critical design review on 1 March 2011. The system was delivered to Lockheed Martin in April 2012, and was mated to the satellite bus the following month.
DigitalGlobe agreed to purchase GeoEye in July 2012, and finalized the merger in January 2013. At the time, each company had a satellite being prepared for launch: WorldView-3 and GeoEye-2. Because WorldView-3 offered multiple short-wavelength infrared channels in addition to the standard panchromatic and multiwavelength channels, the company chose to proceed with its launch and to place GeoEye-2 into storage.
In July 2014, DigitalGlobe announced that GeoEye-2 had been renamed to WorldView-4 to better match the company's branding, and that, due to a projected increase in product demand, the spacecraft's launch had been scheduled for mid-2016. The total cost of the spacecraft, including insurance and launch, is estimated at US$835 million.
The first public image from WorldView-4 was taken on 26 November 2016 and released on 2 December 2016.
In January 2019, WorldView-4 was announced to have suffered a failure in one of its control moment gyroscopes, and was considered no longer usable. WorldView-4 was insured against satellite failure, and in spring 2019 the company owning the satellite, Maxar Technologies, which had acquired DigitalGlobe in 2017, announced that they had received the full US$183 million insurance payment.
