Leica IPAS Freebird is GNSS-IMU processing software designed to improve flight economy and simplify airborne data acquisition workflows.

The software supports accurate image georeferencing by using GNSS raw measurements and tightly coupled GNSS-IMU processing in one step. This helps reduce processing complexity and supports faster, more efficient airborne mapping operations.

Leica IPAS Freebird enables tighter turns between flight lines and does not require continuous satellite lock, contributing to more efficient sensor missions and reduced flight time. According to Leica Geosystems material, it can support up to 25% improvement in flight economy for sensor missions.

The solution is suitable for organisations involved in airborne mapping, aerial surveying, LiDAR data acquisition, photogrammetry, image georeferencing and professional geospatial production workflows.
