- Description
Why DotLas Plus?
Literally, DotLas is a highly integrated device capable of point (= dot) measurement and laser scanning. Thatʼs how this new compound word DotLas came. And Plus here actually refers to something extra, merged applications. By combining the immense power from the existing 2 core technologies in geo-spatial society, it features amazing versatility, and intends to challenge some complex environments where conventional GNSS RTK cannot satisfy. Therefore, it resets the benchmark of GNSS RTK hybrid models and tops itself as the supreme masterpiece in the industry.
Why 1+1＞2 Is True?
① Magicalc = Magic + calculation (Positioning while Satellites Unlocked)
With DotLas Plus, itʼs possible to obtain coordinate information in the way of Mixed Solution in GNSS-unfriendly or even GNSS-denied areas. The SLAM trajectory will help to reverse compute the positional result and continue point measurements when satellites are unlocked. The Magicalc accuracy mainly depends on the unlocked duration, SLAM trajectory distance, and texture details of the new environment.
② AirMeas = Air Measurement (Contactless Measurement)
Have you heard about iPhone AirDrop? AirMeas is somewhat similar to this principle or saying. For some inaccessible zones, DotLas Plus may help to measure in the way of SLAM data capture within scanning range. Just imagine how to measure the center of the manhole cover on the ground, center of a router device installed overhead, etc. Go to the point in pano image overlaid with colorized point cloud, and you will obtain the coordinate automatically instead of reaching there physically.
③ Super Stake-out
On the market, AR stake-out has been applied to more and more RTK receiver models. Generally speaking, AR stake-out goes with visual aided methodology. While AirMeas is to measure the unknown point that is inaccessible, Super Stake-out helps to reach the known point in the way of pano image overlaid with colorized point cloud, which is a powerful reverse application of AirMeas.
About Fixed Solution & Mixed Solution
Fixed Solution means that the GNSS RTK rover and its allocated base station can simultaneously track at least five satellites in common, and then
the rover keeps receiving differential corrections from the base station, which is already widely acknowledged in the geospatial community.
Mixed Solution refers to a reverse computed result scientifically derived from the time synchronization of SLAM trajectory and earlier positional records, which well interprets the Mix&Match Combo. By unlocking the combined power of GNSS+SLAM, it sets out A Brand New Concept to the Industry indeed.
