VectorNav GNSS/INS Systems for Aerial Photogrammetry

Aerial photogrammetry is expanding into new applications and end uses that were previously too costly or impractical. Professional photogrammetry can produce outputs with horizontal (x,y) accuracies in the range of 1 cm (0.4 in) and elevation (z) accuracies of 2 to 3 cm (0.8 to 1.2 in), which enables precise volumetric analysis. In this section, we are going to focus on photogrammetry and the advantages of using a GNSS/INS to provide a more efficient and cost-effective aerial mapping.
