OneWeb: Enterprise LEO Connectivity
OneWeb operates a Low Earth Orbit (LEO) satellite network for wholesale connectivity. Its documented service model reaches governments, businesses, and communities through distribution partners, with an architecture built around near-polar orbits and a ground gateway network. The system is designed for enterprise and mobility services rather than a standard direct-to-consumer residential package, so the terminal, gateway, and local service authorization remain part of the delivered solution.
Founded in 2012 to connect schools, OneWeb filed for Chapter 11 bankruptcy protection in March 2020 and was later rescued by the UK Government and Bharti Global. Eutelsat and SoftBank joined the investor group, while the operating model focused on selling capacity to telecommunications companies, internet service providers, and aviation and maritime partners. OneWeb therefore supplies a wholesale network that partners can integrate into their own services for enterprise, government, and mobility applications. Its low-altitude constellation reduces the path length compared with GEO, while its orbit and gateway design determine where that capacity is usable.
Orbital Architecture and Polar Coverage
OneWeb's constellation uses near-polar orbits to extend coverage toward high latitudes. This orbital choice differs from LEO networks whose first shells concentrated on populated mid-latitudes.
High Altitude LEO and Polar Orbits
The first generation OneWeb constellation is designed to operate from a nearly circular Low Earth Orbit at a relatively high altitude for LEO.
- Altitude: Approximately ( miles). This orbit gives each satellite a larger ground footprint than a lower LEO shell such as the 550 km Starlink shell. Fewer spacecraft can cover a selected area, while the longer path produces higher latency than the lowest LEO orbits and much lower latency than GEO.
- Orbital Inclination: The defining feature of the OneWeb constellation is its use of near-polar orbits, with an inclination of approximately degrees. In a polar orbit, the satellites travel over or very near to the North and South Poles on each pass around the Earth.
The Advantage of Going Polar
Satellites in near-polar orbits pass over high latitudes as Earth rotates below them. A completed constellation can therefore support service in polar regions for trans-polar aviation, Arctic shipping, and scientific or government operations in the Arctic and Antarctica. Actual availability still depends on gateways, national authorizations, terminal geometry, and network capacity; GEO has poor viewing geometry near the poles.
Constellation Size and Manufacturing
The first-generation plan specified 648 satellitesin 12 orbital planes, with 49 satellites assigned to each plane and 60 in-orbit spares in the OneWeb maritime brochure. Those figures describe the Gen 1 constellation plan rather than a permanent operational count. In 2026 Eutelsat's responsible-space description lists 654 Gen 1 satellites at approximately 1,200 km, while other operator documents use older dated counts above 600. The plan, the current operator count, and the number of satellites available to a particular service are separate quantities.
OneWeb formed the OneWeb Satellites joint venture with Airbus and built a high-volume production facility in Florida. The facility applies automotive-style assembly methods to spacecraft and has been described as producing up to two satellites per day, reducing production time and cost compared with bespoke MEO and GEO spacecraft. That manufacturing process supported repeated production of the Gen 1 fleet and the later replenishment orders.
Technology and System Operation: Bent-Pipe Architecture
The way signals travel through the OneWeb network is defined by a bent-pipe satellite communication architecture. A user terminal sends traffic to the satellite, the payload relays it to a gateway that is visible from the same spacecraft, and the gateway connects the traffic to the terrestrial network.
Communication Payload: The Ku-Band
OneWeb's Gen 1 user links use the for communication with user terminals. Feeder links between the satellite and gateway sites use the Ka-band. Ku-band is common in satellite communication, including GEO systems, and its user link has a defined trade-off between available bandwidth and attenuation during rain. The bands describe separate sections of the Gen 1 link budget.
No intersatellite lasers in Gen 1
A defining Gen 1 architectural property is the absence of , or "space lasers". OneWeb's Gen 1 satellites use a bent-pipe route through the ground segment and do not communicate directly with one another in orbit. A packet cannot therefore move from one Gen 1 spacecraft to another through an optical mesh in space, unlike an equipped Starlink generation.
This design is known as a "bent-pipe" architecture. The satellite relays a signal from a user terminal to a gateway within its line of sight, while routing and network processing remain in the ground segment. The payload acts as a relay rather than a complete IP router in orbit. The arrangement resembles an old telephone switchboard that connects one line to another.
In this "bent-pipe" approach, the user terminal and a gateway ground station must be visible to the same satellite at the same time. Service therefore depends on the distribution and location of the ground segment.
Ground segment functions
Because Gen 1 routes traffic through gateways, the ground segment is a central part of OneWeb's operation. The gateway network must be placed so that a satellite serving a terminal can also see a site connected to the terrestrial fibre backbone.
- Satellite Network Portals (SNPs): These secured sites provide gateway functions. Eutelsat documents more than 22 SNP sites with multiple tracking antennas, including antennas in the 2.4 to 3.5 metre range, plus equipment connecting to terrestrial fibre networks. The documented count does not establish a fixed number of antennas at every site.
- Global Distribution: The SNP network includes sites from Alaska and Greenland to Australia and South Africa. A satellite serving a user needs a gateway path to the terrestrial network, so site placement affects coverage and service continuity.
- User Terminals: OneWeb offers User Terminals (UTs) for enterprise markets, including flat-panel electronically steered antennas and mechanically steered parabolic dishes for aviation, maritime, and land mobility applications. The terminal type, antenna tracking method, and service package depend on the customer segment.
OneWeb's Wholesale Business Model
OneWeb's documented commercial model is business-to-business (B2B) and wholesale. The operator sells network capacity to Distribution Partners, which integrate the connectivity into services for their customers. Eutelsat lists telecoms, government, enterprise, aviation, and maritime partners for this model. The public documentation supports a partner-led route to market, while the customer-facing service can still be delivered under the partner's own contract and brand.
Target Markets and Use Cases
The B2B model directs OneWeb capacity toward sectors that need coverage beyond terrestrial networks and predictable satellite connectivity. These sectors include cell-site transport, aircraft, ships, government operations, and remote energy or mining sites where fibre construction is difficult or uneconomic.
- Cellular Backhaul: One of the largest target markets. For mobile network operators like AT&T or BT Group, connecting cell towers in remote and rural areas with fiber optic cable can be prohibitively expensive or impossible. OneWeb offers a satellite-based solution for , allowing these operators to rapidly and cost-effectively extend their 4G and 5G coverage to unserved communities.
- Aviation: Providing high-speed, low-latency in-flight Wi-Fi to commercial airlines and private jets. This allows passengers to have a genuine broadband experience in the air, including video streaming and VPN access.
- Maritime: Delivering connectivity to the maritime industry, including large cargo ships, cruise lines, and luxury yachts, enabling everything from critical operational data transmission to high-speed internet access for passengers and crew on the open ocean.
- Government and Enterprise: Providing secure and resilient communication links for government, defense, and emergency services. It also serves large enterprises in sectors like energy and mining, which often have operations in remote locations far from terrestrial infrastructure.
OneWeb Ownership and Launch History
OneWeb filed for Chapter 11 bankruptcy protection in March 2020 while facing high capital costs and the economic uncertainty of the COVID-19 pandemic.
Later in 2020, the UK Government and Indian telecommunications company Bharti Globalled a joint acquisition, and OneWeb emerged from Chapter 11 protection on 20 November. In April 2021, SoftBank and Eutelsat joined the investor group, with Eutelsat taking a 24 percent stake. The UK obtained a position in satellite communications and positioning, navigation, and timing (PNT) capability. The investment gave it a position in a strategic satellite communications company after Brexit. In 2023, Eutelsat and OneWeb completed a merger that combined the OneWeb LEO constellation with Eutelsat's GEO fleet and created a GEO-LEO service portfolio.
The project relied on Russian Soyuz rockets until the partnership ended after Russia's invasion of Ukraine in 2022. OneWeb then secured launch contracts with SpaceX and India's ISRO to complete deployment of the initial constellation.
OneWeb Constellation Renewal
By 2026-09-10, Eutelsat had ordered 440 additional OneWeb satellites, comprising an initial batch of 100 followed by 340 spacecraft. On the same date it announced a further 229 satellites from Airbus, bringing the new Airbus order total to 669. Eutelsat also selected two dedicated Ariane 64 launches scheduled for 2027 and 2028. The 440 already ordered and under construction are separate from the 229 newly procured units, and neither number means that the satellites are already in orbit. Detailed parameters of a future layer require an operator specification for that configuration.
OneWeb supplies partner-led B2B connectivity for enterprise, government, aviation, maritime, and mobile-network markets. Its 1,200 km near-polar Gen 1 architecture supports high-latitude coverage, while gateway locations, terminal geometry, network capacity, and local authorizations determine where a customer can use the service. The replenishment programme extends the life of the existing network and does not by itself define a new orbital generation. Service continuity still depends on launches, orbit raising, and gateway operations.
