SI-22 Dual-Spectral Surveyor

Overview

The SI-22 is designed for energy auditors and building performance contractors who need a single flight to produce both a geometric surface model and a radiometric heat signature. The 45 MP RGB module builds the orthomosaic while the 640 × 512 thermal sensor, calibrated to ±2 °C, records surface temperatures at 30 Hz, so thermal anomalies on a facade or a solar array can be pinpointed without a second sortie. Both sensors are rigidly mounted on a common three-axis gimbal, which keeps them geometrically aligned and lets the software fuse the two layers without registration drift. RTK positioning is accurate to 1 cm + 1 ppm and the flight controller compensates for lens distortion on the fly, so measured surface temperature and modelled geometry land on the same coordinate. A single battery gives 32 minutes of flight and about 2.2 hectares of coverage at 100 m, and the IP43-rated body tolerates light rain and dust for extended site work.
