FreeFlight Systems is a leading provider of UAV (unmanned aerial vehicle) and drone avionics systems and solutions.
Our next-generation products, developed with over 50 years of aviation expertise, are designed to be future-proof and are used worldwide to enhance the safety, efficiency and affordability of unmanned flight.
Our modular and scalable products can be easily integrated into a wide variety of fixed-wing and rotary UAVs, serving a range of commercial, government and military requirements.
1201 Series SBAS/GNSS Receivers
High-accuracy GNSS positioning for UAVs
The 1201 Constellation Series is designed to provide robust, highly reliable GPS position data for ADS-B, IFF Mode 5 and other UAV detect-and-avoid and identification systems.
Ideal for urban air mobility (UAM) applications, the lightweight sensors can be integrated into a variety of OEM drone platforms or retrofitted to existing aircraft.
The standalone unit processes GPS signal data, and Satellite Based Augmentation System (SBAS) signal data where available, that is compliant with the Wide Area Augmentation System (WAAS) standard used in the United States. It provides high-accuracy position, velocity, time, and integrity (PVT&I) data that is crucial for precise UAV navigation applications.
Rated for use in harsh environments, the rugged, low-SWaP (size, weight and power) unit interfaces to TAWS (Terrain Awareness Warning Systems), FMS (Flight Management Systems), NMS (Navigation Management Systems), and other systems requiring GPS data via an ARINC 743 2-wire interface, and meets all standards for a TSO-C145c Class Beta 1 device.
Altitude measurement for safety-critical unmanned aircraft applications
Our UAV radar altimeters provide high-reliability measurements of altitude above terrain for critical drone navigation and safety applications.
Designed with state-of-the-art DSP-based RF electronics, the robust units have been engineered to eliminate spurious terrestrial datalink spectrum interference, including 5G.
Featuring rugged enclosures designed for use in mission-critical and military-grade environments, the radar altimeters can be easily retrofitted into existing unmanned aircraft. They can be interfaced with our RAD-40 and RAD-45 LED display indicators, or with a variety of popular glass displays and legacy analog indicators.
All models feature RS 485/422, RS-232 and ARINC 429, with some additionally supporting Ethernet connectivity and USB On the Go (OTG).
