ALPS 2
ALPS1 allows you to shoot a group of photos or videos in real time, obtaining coordinates for hundreds of points within minutes. It outpaces traditional RTK in data acquisition speed.
With laser measurement, ALPS1 has a broader working range and fewer blind spots, enabling remote measurements in areas with poor GNSS signal quality. Previously challenging spots, like spaces under rooftops and areas with obstacles, are now easily measurable
