The Next-generation INS/GNSS Post-processing Software Full data available upon request at marketing@sbg-systems.com www.sbg-systems.com Thank you Hydro Systems Development (HSD Japan) for their kind collaboration. SURVEYING UNDER BRIDGES MADE EASY This survey has been done with an APOGEE INS under very challenging conditions for the GNSS receiver (red dots). The boat is crossing multiple times three large bridges including one made of steel. With Qinertia and its unique 100% in-house GNSS/INS tightly coupled forward / backward processing, data collected under the bridges are fully exploitable (blue / green trajectory). Quality: Green -> centimetric position; Blue -> decimetric < 30cms; Red -> Raw GNSS data Log duration: 2h15 Processing Time: < 2 mins Example: up to 80 seconds outages and multi-path eff ects 95% positions < 2 cms Max error < 30 cms Easy export to third party software (SBET/ ASCII) The Fastest PPK Software Long GNSS Outages Handling Easy & Powerful Exporter Å GNSS Altitude (m) - Merged Å Altitude (m) - Merged Altitude – Left GNSS only, Right: Post-processed
