Viasat Non-Terrestrial Network (NTN) Satellite Connectivity for Connected Vehicles
Viasat, Inc.
Viasat’s Narrowband Non-Terrestrial Network (NB-NTN) satellite connectivity technology for the automotive industry is a pioneering, standards-based solution that enables connected vehicles to switch between terrestrial cellular networks and satellite communication.
This innovation allows vehicles to remain "always-on" with connectivity, with the capability to eliminate cellular dead zones that have historically limited safety, diagnostic capabilities, and the efficiency of modern, connected vehicles. Built using 3GPP Release-17 and above NTN standards, this innovation allows cars, trucks, and logistics fleets to connect directly to Viasat's highly reliable, global L-band satellite network; by utilising cost-effective line-fit methods, or retrofitted chipsets with simple roof-mounted antennas. This removes the need for traditional, proprietary satellite hardware and can pave the way for mass take up of satellite-enabled connectivity for the automotive industry. In practice, standards-based NTN can operate as an intelligent, automatic back-up as follows: In remote areas or cellular "black spots", the technology can automatically transition to Viasat's geostationary satellite network to maintain a continuous, bi-directional flow of critical telemetry, messages, and safety alerts In urban areas, the vehicle communicates via traditional terrestrial cellular networks, while satellite connectivity can act as an effective ‘overlay’ to ensure services reliability and resilience. As the automotive industry shifts toward software-defined vehicles (SDVs), autonomous driving, and proactive fleet management, Viasat's NB-NTN connectivity technology can help solve one of the sector's most persistent bottlenecks: unreliable coverage. Our industry leading innovation and demonstrations directly support the industry across three critical pillars: 1. Revolutionising Vehicle Safety & Telematics Terrestrial cellular networks cover only a fraction of the earth's landmass. NB-NTN connectivity for vehicles now can help save lives on roads by keeping drivers connected with emergency services wherever they are. Further in the future, autonomous and semi-autonomous vehicles - including the 33 million driverless cars projected to be on global roads by 2040 – could access satellite connectivity to enable the next generation of connected transport systems. Right now, Viasat's NB-NTN technology can ensure reliable, consistent communication. This supports: Enhanced Safety Applications: Continuous access to emergency SOS services, automated accident detection, and real-time hazard alerts, regardless of location. Passenger safety and experience: Safety is the number one priority for public modes of transport and satellite connectivity allows for enhanced safety measures, such as remote monitoring of vehicle conditions, driver behaviour analysis, and real-time updates for emergency response systems. Predictive maintenance alerts: Connected vehicles could send real-time updates to drivers or transport operators, including updates like tire pressure, engine temperature, and fuel or oil levels. Improved information could alert drivers a breakdown Fleet tracking and management: Real-time visibility significantly enhances safety and fleet management by accurately identifying where transport assets are at any time, understanding fuel usage, and providing feedback on whether drivers are adhering to safety procedures, as well as broader driver behavior. This improve safety, sustainability and efficiency for last-mile deliveries and logistics firms, so quality can be tracked for even the most perishable items, such as foodstuffs or medicine cold chains. Improved supply chain management: With more reliable and accurate data about the movement of goods, major supply chain operators could plan routes more efficiently and access real-time traffic updates for drivers. It could also allow real-time updates for drivers to improve driving efficiency, for example by slowing down if traffic is up ahead. This all works to save miles, fuel, money, and emissions for operators. 2. Fostering a Cost-Effective, Open Ecosystem for All Viasat is one of the founding member of the Mobile Satellite Services Association (MSSA), which is advocatng for an open, standards-based approach. By integrating satellite capabilities directly into standard automotive chipsets, we can aim to dramatically lower hardware costs, reduce engineering complexity, and accelerate the commercial timeline—with mainstream adoption projected to scale starting in 2027. Through Viasat's NB-NTN connectivity, we are helping the automotive sector bridge the gap between space and terrestrial networks, delivering the robust, resilient, and always-on safety architecture required for the future of transportation. 3. Building Industry Ambition via Proven, Real-World Reliability & Performance The technical feasibility and robust performance of this solution have been thoroughly demonstrated in rigorous real-world environments, including the following demos: Successful World-First Trials in Paris & Sacramento: Collaborating with BMW and the 5G Automotive Association (5GAA) in Paris and showcasing world-first voice call capabilities during Mobile World Congress 2026, we proved that critical emergency services, hazard warnings, and GPS tracking continue to function flawlessly via our networks when terrestrial coverage drops. Voice Capabilities Demonstration: At MWC Barcelona, alongside Cubic3, we demonstrated live, bi-directional satellite-enabled voice calls directly over our satellite network, proving that vital voice communications can be supported using AI compression. The Brazil Highway Trial: In partnership with GuardianSat, Quectel, Acceleronix, Viasat equipped a variety of vehicles to travel over 35,000 km across a rugged 250 km highway corridor between Curitiba and Blumenau—a region notorious for cellular black spots. Over 40 days of testing, including periods of severe heavy rain, the system achieved outstanding metrics and vehicle telemetry data (tracking over 1,000 parameters, including precise GPS location, acceleration, and exhaust temperatures) was successfully transmitted to headquarters in just 3 to 5 seconds on average.
