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 ...
Intelsat 33e, also known as IS-33e, was a high throughput (HTS) geostationary communications satellite operated by Intelsat and designed and manufactured by Boeing Space Systems on the BSS 702MP satellite bus. [1] [2] It was the second satellite of the Epic NG service, and covered Europe, Africa and most of Asia from the 60° East longitude ...
Sea-based missile defense test STSS satellites target and help to intercept an intermediate-range ballistic missile (IRBM); destruction of the IRBM on impact. July 2011. 8 July 2011; STSS test on short-range air-launched target (SRALT) This test proved the STSS's ability to track dim objects that have extremely short flight timelines.
In 2009, a WAAS satellite sent the initial L5 signal test transmissions. SVN-62 , the first GPS block IIF satellite, continuously broadcast the L5 signal starting on 28 June 2010. As a result of schedule delays to the GPS III control segment, the L5 signal was decoupled from the OCX deployment schedule.
CryoSat-2 uses radar to achieve similar results, while ICESat-2 has a laser system. Radar can penetrate the ice sheet’s surface and through clouds. Laser signals cannot operate when clouds are ...
COSMO-SkyMed (COnstellation of small Satellites for the Mediterranean basin Observation) is an Earth-observation satellite space-based radar system funded by the Italian Ministry of Research and Ministry of Defence and conducted by the Italian Space Agency (ASI), intended for both military and civilian use.

The STAR-2 Bus is a fully redundant, flight-proven, spacecraft bus designed for geosynchronous missions.. It is a satellite platform, designed and developed by Thomas van der Heyden for the Indonesian Cakrawarta satellite program in the early 1990s, now manufactured by Northrop Grumman Innovation Systems with an apogee kick motor to place a communications satellite into geostationary orbit, a ...
The satellite was launched on 1 March 2018 [3] and reached geostationary orbit on 12 March 2018. [8] In May 2018, during the satellite's testing phase after launch, a problem was discovered with its primary instrument, the Advanced Baseline Imager (see Malfunctions, below). [9] [10] GOES-17 became operational as GOES-West on 12 February 2019. [2]
