Riga, Latvia — November 25, 2025. SPH Engineering announces the availability of two new ground-penetrating radar systems optimized for UAV integration: MALÅ GeoDrone 600 and Zond Aero 600 NG.
Both 600 MHz antennas significantly enhance high-resolution subsurface investigations with drones, supporting applications in engineering surveys, utility mapping, archaeology, environmental studies, and geophysical research.
With the addition of these two sensors, SPH Engineering strengthens its position as the leading provider of drone-based GPR solutions, enabling surveyors to capture consistent, high-quality subsurface data in areas difficult, slow, or unsafe to access with traditional ground instruments.
Operating at 600 MHz, both antennas offer an effective balance between penetration depth and fine near-surface resolution.
Typical penetration from the drone is up to 2 meters, depending on the surface conditions, while SPH Engineering’s True Terrain Following ensures stable antenna height to maintain data quality and repeatability.
Compared to ground-based carts or vehicle systems, the UAV-borne configuration enables operators to:
The MALÅ GeoDrone 600 combines the reliability of MALÅ instrumentation with SPH Engineering’s fully integrated drone workflow. Designed for precision engineering, utility detection, and geophysical mapping, the antenna produces clear, high-quality radargrams suitable for detailed structural assessment and shallow subsurface characterization.
Key Specifications
The Zond Aero 600 NG is a next-generation shielded antenna designed specifically for airborne GPR operations.
It offers a strong signal-to-noise ratio, improved ground coupling at low altitudes, and robust performance over natural terrain—making it particularly suitable for geophysical research, archaeology, and environmental geoscience.
Key Specifications
Both antennas are fully compatible with SPH Engineering’s UgCS flight planning software and the SkyHub drone onboard computer, enabling:
“Adding the MALÅ GeoDrone 600 and the Zond Aero 600 NG to our UAV-GPR portfolio reflects the rapid industry demand for drone-based subsurface mapping,” said Alexey Dobrovolskiy, CEO of SPH Engineering.
“Surveyors, engineers, and researchers can now choose between two high-performance 600 MHz antennas depending on their project requirements. Our goal is to deliver a complete, reliable workflow—from flight automation to secure data logging—that transforms how near-surface geophysics is conducted.”
