Firefly is Pixxel’s operational hyperspectral constellation, delivering high-resolution VNIR (Visible–Near Infrared) imagery designed for frequent global monitoring.
The Firefly sensors provide hyperspectral imagery across 135 spectral bands spanning the 470–900 nm range, at a 5.4-meter Ground Sample Distance (GSD). Users can select up to 45 bands per capture, enabling application-specific spectral optimization.
