Meridian
Sub-centimetre RTK/PPK photogrammetry for terrain modelling.
Initialising inspection bay
Overview
Meridian is a multi-frequency RTK/PPK photogrammetry platform that reaches sub-centimetre accuracy without dense ground control, generating bare-earth digital terrain models (DTM) across corridors and large sites.
01
Multi-frequency RTK/PPK
Sub-centimetre positioning with minimal ground control points.
02
Bare-earth DTM
Filtered terrain models for design, drainage and corridor planning.
03
Grid flight autonomy
Automated overlap and speed optimisation for large mapping runs.
