Leica VADASE
Leica VADASE (Velocity and Displacement Autonomous Solution Engine) provides an in-depth look into fast movements using unique processing algorithms. In real time, accurate high-rate velocity and displacement information of various activities and structures are provided to engineers and researchers for a complete, precise and reliable monitoring solution. Leica VADASE delivers actionable information independent of any GNSS RTK correction service in real time. Displacement events are streamed out or recorded onboard a single stand-alone GNSS receiver, and the user can be notified by email. With this instant information, professionals receive a deeper understanding of how structural movements occur and can take necessary actions to mitigate damages and potentially save lives with:
– Fully-autonomous, stand-alone receiver – no GNSS RTK correction services needed
– Instant information on fast relative displacements up to 20 Hz delivered in real time
– Integration into early warning systems
