Trimble has launched the Trimble GNSS Smart Target Base Station for high-accuracy mapping from Unmanned Aerial Vehicles (UAVs). The announcement was made at INTERGEO 2017, the world's largest conference on geodesy, geo-informatics and land management.
The system consists of a survey grade, multi-frequency, multi-constellation GNSS reference station complete with a foam Ground Control Target with integrated carrying case. The Smart Target Base Station logs the raw GNSS observables required to perform centimeter level post-processed Differential GNSS positioning of UAVs, and acts as a photo-identifiable Ground Control Point (GCP) for quality control.
Cost effective, simple to operate, and supported by both the Applanix POSPac UAV GNSS-Inertial post-processing software for Direct Geo-referencing on UAVs and Trimble UASMaster Photogrammetric software, the Smart Target Base Station makes aerial mapping from UAVs easier than ever. Simply place the foam target with its receiver in the project area, stake it down. With the included Smartphone app or web UI, users can remotely begin logging the raw GNSS observables data collected by the target that is required for post processing.
At the end of the mission, you can retrieve the target and download the raw GNSS data along with the data collected from the Trimble APX UAV GNSS-Inertial system installed in the UAV. Global coordinates of the reference station are computed automatically using the Trimble Centerpoint RTX post-processing service in POSPac UAV, or if local coordinates are desired, the foam target can be centered over an existing reference point.
The Trimble GNSS Smart Target Base Station operates autonomously for up to 4 hours with an embedded lithium ion battery. Extended operation can be achieved with a user supplied external USB battery. It is now available globally through Applanix sales channels.
