In order to make drone surveying accurate, Japan-based Aerosense has commercialized its AEROBO Marker solution for drone surveying using the u‑blox NEO‑M8T timing module. Using this high-performance positioning module, Aerosense engineers could solve the high position accuracy challenge while developing their solution, according to u-blox.
“Created to compute absolute time to within 20 nanoseconds using incoming GNSS signals, the NEO-M8T lets users access RAW GNSS data output, making it attractive for positioning applications that rely on post-processing GNSS data to enhance location accuracy”, said u-blox.
Aerosense’s surveying solution is designed to reduce the time spent surveying construction sites. By combining ground markers equipped with a GNSS receiver with surveying drones and cloud-based data processing, they have converted huge workloads into a user-friendly application for anyone.
The surveying operation on the site involves setting up ground markers fitted with u‑blox NEO‑M8T high-performance GNSS receivers. The smart ground markers send the GNSS data they receive to the cloud, where it is post-processed using a static surveying algorithm to achieve high accuracy.
AEROBO’s solution can transform high-resolution drone images into a survey-accurate map by using the absolute geographic coordinates of specific points on the surveyed terrain. Images gathered by overflying the terrain with the drones are combined to create centimeter-precise outputs, including orthomap views, 3D models, and point clouds, according to the announcement.
