The global market for Multilateration (MLAT) Surveillance systems is estimated at $1.85 billion for the current year, with a projected 3-year CAGR of 6.2%. Growth is fueled by global air traffic recovery, airport modernization programs, and the need for cost-effective surveillance in areas where traditional radar is unfeasible. The single greatest opportunity is the adaptation of MLAT technology for the rapidly emerging Unmanned Aircraft Systems (UAS) and Urban Air Mobility (UAM) markets, creating a new, high-growth demand vector beyond traditional air traffic management.
The global Total Addressable Market (TAM) for MLAT systems is currently valued at an estimated $1.85 billion. The market is projected to grow at a Compound Annual Growth Rate (CAGR) of 6.7% over the next five years, driven by infrastructure upgrades and the need to enhance airspace visibility and safety. The three largest geographic markets are 1. North America, 2. Europe, and 3. Asia-Pacific, with APAC demonstrating the highest growth potential due to new airport construction and modernization initiatives.
| Year | Global TAM (est. USD) | CAGR (%) |
|---|---|---|
| 2024 | $1.85 Billion | - |
| 2026 | $2.10 Billion | 6.6% |
| 2029 | $2.55 Billion | 6.7% |
Barriers to entry are High, characterized by stringent safety certifications (e.g., ED-142 in Europe), significant R&D investment in proprietary algorithms, high capital intensity, and deep, long-standing relationships with national Air Navigation Service Providers (ANSPs).

⮕ Emerging/Niche Players * ERA a.s. (Czech Republic): A highly respected specialist focused solely on multilateration and ADS-B systems, known for technological innovation and flexibility. * Frequentis (Austria): Traditionally a leader in voice communications, now expanding into surveillance and information management to offer integrated tower solutions. * Searidge Technologies (Canada): A subsidiary of NATS, specializing in digital and remote tower solutions that heavily integrate MLAT and camera data.
The price of an MLAT system is a complex build-up of hardware, software, and services. Hardware, including ground-based sensors, central processing units, and network infrastructure, typically accounts for 40-50% of the initial project cost. Software licensing, which covers the core processing algorithms and user interfaces, represents another 20-25%. The remaining 25-40% is allocated to critical services, including site surveys, installation, integration with existing ATM platforms, training, and multi-year maintenance and support contracts.
Total Cost of Ownership (TCO) is a more critical metric than initial purchase price, as ongoing software maintenance and hardware support are significant. The three most volatile cost elements are tied to specialized inputs where supply is constrained and demand is high.

North Carolina presents a strong and growing demand profile for MLAT systems. The state is home to Charlotte Douglas International Airport (CLT), a major hub requiring advanced surface management, as well as numerous regional airports pursuing modernization. The significant military presence (e.g., Fort Bragg, Seymour Johnson AFB) creates parallel demand for military-grade air traffic and range management systems. While there are no prime MLAT manufacturers headquartered in NC, the state's robust aerospace ecosystem—including component suppliers, engineering services firms, and the presence of Collins Aerospace—provides significant local capacity for system installation, integration, and long-term support. A favorable business tax structure and a deep talent pool from leading engineering universities enhance its attractiveness for project deployment.
| Risk Category | Grade | Justification |
|---|---|---|
| Supply Risk | Medium | High dependency on a few semiconductor foundries for critical RF and processing components. |
| Price Volatility | Medium | Exposed to fluctuations in semiconductor, raw material, and specialized labor costs. |
| ESG Scrutiny | Low | Primary product function enhances safety and fuel efficiency (reduced taxi/hold times), a net positive. |
| Geopolitical Risk | Medium | Systems are critical national infrastructure, subject to export controls and "buy national" procurement policies. |
| Technology Obsolescence | Medium | Risk of disruption from next-gen satellite-based solutions or new sensor tech within a 5-7 year horizon. |
Mandate Technology Roadmaps in RFPs. To mitigate obsolescence risk from UAS and AAM integration, require all Tier 1 bidders to provide a 5-year funded technology roadmap. This submission should detail planned upgrades for low-altitude tracking and data fusion. This shifts focus to TCO and future-readiness over initial CapEx, ensuring the selected system remains viable for its full 10-15 year lifecycle.
Qualify a Niche Specialist for Secondary Buys. For smaller, non-hub airport upgrades, initiate a qualification process for a niche supplier like ERA a.s. This introduces competitive tension against incumbents (Saab, Thales), potentially reducing lifecycle service costs by est. 5-10%. It also provides supply chain diversification, mitigating geopolitical risk associated with reliance on a single-nation prime contractor for the entire network.
