Viasat has announced plans to deploy a critical Trajectory-Based Operations (TBO) facility in the Asia Pacific region, aiming to support next-generation air traffic services. The initiative centers on the use of Iris and TBO technologies, which are designed to modernize air traffic management by enabling more efficient and predictable operations.
Iris provides secure, satellite-based datalink services that facilitate initial 4D trajectory sharing between aircraft and controllers. This capability helps avoid holding patterns, optimize flight routes, and maintain continuous climb and descent profiles, leading to reduced fuel consumption and lower emissions. Additionally, Iris integrates with global standards such as Flight and Flow Information for a Collaborative Environment (FF-ICE) and System Wide Information Management (SWIM), promoting real-time collaboration among airlines, air navigation service providers (ANSPs), and airports. This integration aims to create a unified ecosystem for smarter flow management and harmonized operations.
The underlying architecture of Iris combines Viasat’s L-band satellite constellation with secure ground facilities to provide reliable data links for both air traffic services and airline operations. After successful implementation in Europe—where it has optimized flight paths, reduced delays, and contributed operational as well as environmental benefits—Iris is now being introduced in Asia Pacific. The program also aligns with Single European Sky ATM Research (SESAR) objectives and International Civil Aviation Organization (ICAO) standards.
Joel Klooster, SVP Aircraft Operations and Advanced Air Mobility at Viasat, commented: “Iris’s continued momentum and success in Europe highlights the role satellite connectivity plays in transforming air traffic management. Asia Pacific is one of the fastest growing regions for air traffic, requiring coordination across many countries and regions. Introducing Iris to the region as an enabler of TBO will help support the increased air traffic volumes in an efficient manner and enable more predictable operations across its 39 diverse states, laying the foundation for harmonized air traffic management in one of the world’s most exciting regions.”
The new Integration Test Facility (ITF) is expected to become operational in 2026. According to Viasat, this facility will enable comprehensive testing and integration of advanced technologies aimed at improving aviation connectivity and safety standards worldwide.
