OneWeb’s global broadband vision ------------------------------------- OneWeb claims its low Earth orbit satellite network can deliver fast broadband to ships, aircraft and the most remote locations on Earth ------------------------------------- BROADBAND SYSTEM Terminal: Encrypts data and sends to satellite fleet overhead (at up to 32Mbps*) Satellite: Signal beamed to network portal on Earth (at up to 177Mbps) and back into internet Time: 1/10th sec ------------------------------------- SATELLITE CONSTELLATION 74 of planned 648 OneWeb satellites launched to date Satellites, each with life expectancy of five years, occupy 12 polar orbits Mar 2020: OneWeb asks U.S. Federal Communications Commission (FCC) to approve expansion of its constellation of satellites to 48,000. Company files for Chapter 11 bankruptcy protection ------------------------------------- WHY LOW EARTH ORBIT IS FASTER OneWeb low Earth orbit (LEO): 1,200km Latency (delay in sending and receiving data): 50-100 milli- seconds (ms) Note: Doubts remain as to viability of OneWeb to double as sat-nav system Galileo sat-nav system, medium Earth orbit (MEO): 23,222km Latency: Around 370ms Geostationary orbit (GEO): 35,000km Latency: 560ms ------------------------------------- Jun 2020: UK government enters into joint venture with India’s Bharti Global to buy loss-making OneWeb for $1bn. UK set to lose access to EU Galileo system after Brexit ------------------------------------- *Megabits per second – 1 byte = 8 bits, therefore 32Mbps = 4 megabytes (MB) of data per second Sources: OneWeb, The Parliamentary Review, Financial Times, E&T © GRAPHIC NEWS
