OneWeb’s 648 KU-band satellite constellation in 650 nm low Earth orbit promises global connectivity with 100 Mbps download speeds and super-quick, 50-millisecond latency times.
expect download speeds of up to 195 Mbps and 100 Mbps nominal speeds with 50-millisecond latency times. Sat- com Direct, among other firms, offers complete OneWeb avionics and monthly subscription packages. Gogo now is offering Galileo, a hybrid ATG/SatCom IFC system, com- bining its 5G ATG AVANCE package with OneWeb LEO KU-band SatCom. There’s a choice of two electronically steered, phased-array antennae, a 22-pound FDX unit tailored for turboprops and light jets, and a 45-pound HDX unit suited to installation atop large cabin aircraft. Galileo installation prices typically will run $240,000 to $270,000, says Gogo president Sergio Aguirre.
The third choice is SpaceX’s Starlink, a dark horse in the business aviation LEO IFC competition that choos- es to keep its business aircraft avionics developments cloaked in secrecy. Starlink uses both KU- and KA-bands for transmissions between aircraft terminals and satel- lites to achieve up to 150 Mbps download and 50 Mbps upload speeds. Currently, there are more than 4,500 ful- ly functioning Starlink satellites in 300 nm orbit. SpaceX plans to grow the constellation 12,000 satellites, possi- bly up to 42,000 space vehicles, arranged in 184 nm, 300 nm, and 600 nm shells. The company is launching about 60 Starlink satellites per month.
