Diagram of AN/SPY-3 vertical electronic pencil beam radar conex projections. X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM).
WorldView-3 (WV 3) is a commercial Earth observation satellite owned by DigitalGlobe.It was launched on 13 August 2014 to become DigitalGlobe's sixth satellite in orbit, joining Ikonos which was launched in 1999, QuickBird in 2001, WorldView-1 in 2007, GeoEye-1 in 2008, and WorldView-2 in 2009.
The APG-63(V)3 radar is a more modern variant of the APG-63(V)2, applying the same AESA technology utilized in Raytheon's APG-79. The (V)3 is currently being retrofitted into F-15C/D and deployed in Singapore's new F-15SG aircraft and Saudi Arabia's new F-15SA aircraft. Raytheon delivered the first prototype APG-63(V)3 system in June 2006. [2]

Sentinel-3 is an Earth observation heavy satellite series developed by the European Space Agency as part of the Copernicus Programme. [ 4 ] [ 5 ] [ 6 ] As of 2024, it consists of 2 satellites: Sentinel-3A and Sentinel-3B .
If r > 1, then the series diverges. If r = 1, the root test is inconclusive, and the series may converge or diverge. The root test is stronger than the ratio test: whenever the ratio test determines the convergence or divergence of an infinite series, the root test does too, but not conversely. [1]
