Digital Aviation Solutions
vtt systems is a leading provider of modern digital solutions for the aviation industry.Our customers include airports, airlines, federal agencies, and fleet operators, as well as other organizations involved in airspace and ground operations.
vtt develops and operates integrated 2D and 3D situational awareness systems for both flight and ground operations.These solutions combine display, monitoring, analytics, automation, and AI-driven learning systems to enhance safety, efficiency, and regulatory compliance across all areas of aviation.
In addition to our SaaS platforms, we design and manufacture dedicated hardware for a wide range of ground-based and airborne applications in our in-house laboratories.
01Solutions
We provide comprehensive digital solutions developed and operated entirely in-house. This includes the operation, maintenance, and technical support of all systems to ensure continuous, reliable performance.
Because safety and reliability are essential in aviation, we place particular emphasis on secure and uninterrupted operation.More than 700 airports and thousands of users worldwide rely on our technology every day.

• AI Systems and Machine Learning• Multilateration Systems (WAM, MLAT)• Spoofing and Jamming Detection Systems• Neural Text-to-Speech and Speech-to-Text• Predictive Maintenance and Asset Tracking• Remote Maintenance and Secure Data TransferAviation Requires Reliable Data
Unlike other providers who rely on privately operated and inherently unreliable data sources, we use only data generated by our own receiver network.This guarantees maximum accuracy and reliability, with dedicated receivers deployed directly at our customers’ sites.
Our multilateration (MLAT) system enables precise detection and localization of aircraft that do not comply with Mode-S or ADS-B regulations — both in the air and on the ground.This allows us to provide each customer with a high-precision MLAT capability tailored to their operational environment.
With a network of over 1,000 receivers worldwide and more than 700 in the United States alone, we operate the most capable privately managed receiver network in the industry.
Data Security and State-of-the-Art IT
All data transmitted from receivers to our backend is end-to-end encrypted, with each device using an individual encryption key.Receiver software is centrally managed, digitally signed, and version-controlled. Our IT infrastructure is fully cloud-based (AWS) and leverages all available tools for data protection, redundancy, and continuous security auditing by independent experts.
Efficiency, Passion, and Innovation
We operate our systems with a small, aviation-enthusiastic team based in the USA, Canada, and Europe.Our lean structure gives us agility, direct communication, and outstanding cost efficiency.

We support airports and aerodrome operators with solutions tailored to their specific operational and regulatory environments.
Our systems provide visual situational awareness and data-driven analytics that help optimize workflows, improve operational efficiency, and maintain a comprehensive, real-time overview of all airport activities.
Through our statistical tools and reporting functions, airports can generate reliable documentation for regulatory compliance, funding applications, infrastructure planning, and maintenance audits.For noise management and public feedback, our integrated Noise Complaint Platform allows airports to correlate citizen reports with actual flight movements, providing transparent and verifiable evidence for authorities and stakeholders.
Our drone detection technology enables aerodromes to take timely countermeasures and ensure that flight operations remain unaffected by unauthorized drone activity.
For smaller, unattended aerodromes, our solutions provide seamless digital documentation and interfaces to electronic flight logs, where required by regulation.
FIDS
Passengers benefit from our customizable FIDS (Flight Information Display Systems), available both on-site and online. This provides regional and smaller airports with a professional public presence and a foundation for growth, passenger satisfaction, and long-term loyalty.
Airlines and Fleet Operators
Collaborative Decision-Making (CDM)We help airlines achieve smooth and efficient turnaround operations.
Accurate, high-resolution data on all ground activities between landing and take-off enables early detection of delays and proactive management of flight schedules.Our systems enhance coordination between handling agents, maintenance teams, and flight operations.
We provide a critical foundation for shared situational awareness, improving decision-making within aerodromes by making relevant surface operations data accessible to all local stakeholders.
Authorities and Regulatory Agencies
We support civil aviation authorities and government organizations with reliable, real-time operational data to enhance situational awareness and regulatory oversight.Our systems deliver an up-to-date operational picture that extends beyond legacy infrastructure, enabling faster and more data-driven decisions.
Aviation Authorities
For aviation authorities, we provide FIR overflight billing systems that ensure accurate, transparent, and traceable accounting processes.
Drone Remote ID
Our integrated drone detection hardware not only supplies data to the respective aerodrome but also enables the real-time transfer of drone movement information into centralized databases for national airspace management.
03Research &Development
Reliable data can only be obtained through reliable hardware.Our decades of experience in electronics, RF engineering, industrial IoT, and encryption technologies ensure dependable and secure solutions for critical infrastructure applications.
We design and manufacture dedicated and certified receivers for UAT, FLARM, ADS-B, ADS-C, ADS-L, and AIS Drone ID, and operate one of the largest independent MLAT/WAM networks in the United States, with more than 800 receivers.Our systems are remotely monitored and maintained by our national subsidiaries.
With extensive RF expertise, we develop specialized antennas for a wide range of frequencies, with a focus on environmental resistance and long-term reliability, even in harsh conditions.
Serial production is carried out by local partner companies to comply with regional manufacturing and certification standards.
