Nitro is an advanced terrain following system that revolutionizes aerial surveys and exploration missions, enabling efficient navigation in challenging landscapes. Combining radar technology with precise surface tracking capabilities, Nitro allows flying low altitude geophysics surveys and conquering mountainous terrains with confidence. Its state-of-the-art radar-based system enables flying close to the ground while avoiding obstacles, eliminating the need for extensive preparation like creating digital elevation models (DEMs). Nitro performs optimally in all weather conditions and offers real-time ground surface measurements through the canopy, saving time and resources. Compatible with Ardupilot Quads and VTOL aircraft, Nitro seamlessly integrates into existing setups, offering reliable and efficient results for aerial navigation and geophysics surveys.
