Persistent drones are reshaping how mission-critical operations maintain aerial presence—accurately, continuously, and confidently
Hoverfly Technologies’ tethered unmanned aerial systems (TeUAS) are designed to remain aloft for extended durations, functioning more like aerial infrastructure than traditional drones—anchored in place above a fixed location.
TeUAS drones are engineered for elevated permanence—holding position for hours or even days. When long-duration ISR (intelligence, surveillance, reconnaissance), communications relay, or overwatch is needed, Hoverfly’s systems are ready to deploy within minutes.
Most notably deployed by the U.S. Army, where the TeUAS serve as Variable Height Antennas (VHA), they provide persistent, elevated nodes that extend communication networks. The same platforms also support payloads for ISR (intelligence, surveillance, reconnaissance), electronic warfare (EW), radio relay, and counter-UAS missions in harsh and all-weather environments.
Hoverfly began a comprehensive technical review to upgrade its onboard GNSS systems. The team needed a receiver that could consistently deliver sub-metre accuracy, even in crowded radio frequency urban environments or defence settings.
That search led them to Septentrio’s mosaic-X5, a compact, low-power, multi-constellation, multi-frequency GNSS receiver optimised for space-constrained, mission-critical systems. It immediately stood out for its blend of precision, resilience, and integration flexibility—and has since become a reliable component of Hoverfly’s tethered flight systems.
“Our system can be deployed from case to elevation in less than 10 minutes, with an average ascent time of 90 seconds from ground to 200 feet. It’s simple: unbox, assemble, plug into a power source, and you are flying.”
What you will learn
Featuring interviews with Hoverfly and Septentrio, you will learn about the key criteria for GNSS positioning solutions for persistent tethered drones, including multi-constellation, multi-frequency capability, low size, weight, and power (SWaP), and interference mitigation, like jamming and spoofing.
