Submit Processed Kinematic (PPK) has been the positioning tech of selection for the previous few years. Drone operators have seen some great benefits of PPK over RTK within the quest elevated effectivity and accuracy with much less dependence on Floor Management Factors (GCPs). Now Exact Level Positioning (PPP) is coming into focus as a technique to obtain excessive accuracy, with its personal distinctive traits, benefits and drawbacks. Klau Geomatics has now launched refined processing that brings PPP and PPK collectively in an optimised extremely correct resolution that works anyplace with none base station information.
PPP will not be that new, it has been round for a few a long time. Solely just lately has the know-how reached an accuracy stage appropriate for drone surveying, mapping and inspection purposes.
PPP makes use of exact satellite tv for pc clock and orbit corrections, decided from floor monitoring stations across the globe. It doesn’t require any base station information or radio hyperlinks to realize excessive accuracy.
Historically it took 14 days for the clock and orbit correction information to be obtainable. Klau Geomatics has created a revolutionary new hybrid PPK/PPP processing service with entry to the ultimate clock and orbit corrections simply minutes after the mission.
The important thing worth proposition of Klau Geomatics PPP/PPK is that it’s autonomous, it really works anyplace, requires no different person inputs, akin to base station information and radio/GSM hyperlinks, both quickly after the mission in put up processing (like PPK) or actual time (like RTK). It simply works by itself to realize this very excessive accuracy, whatever the location of the person. Correct datum and tectonic plate movement corrections, particular to completely different international locations and areas, are mechanically utilized to ship essentially the most correct options.
Actual time PPP is effective to these requiring exact actual time navigation. Revolutionary specialist drone options carrying cameras and sensors could require cm stage accuracy for drone navigation or exact actual time sensor information integration. Excessive precision GNSS information fed into an INS (Inertial Navigation System) will allow extra correct Kalman filtering for exact stay sensor orientation.
Drone supply is one other utility requiring correct positioning, to journey lengthy distances (past the vary of RTK and different differential programs) to land on a small goal.
Close to Actual Time PPP is extra relevant to inspection, surveying and mapping. The drone inspection trade now sees the necessity for absolute accuracy to analyse change over time on 3D belongings. Klau Geomatics NRT know-how makes that straightforward and repeatable, anyplace. The exact corrections are utilized to information from custom-tuned KlauPPK GNSS receivers within the KlauPPK put up processing software program to allow centimetre stage accuracy anyplace on the earth with out the necessity for RTK, CORS or native base station information.
Hybrid Processing. In some areas akin to US, Europe, Japan, New Zealand and Australia, the achievable accuracy is much more refined because of the Klau Geomatics hybrid terrestrial multi station and PPP algorithm. Information from as many as 15 dependable long-range CORS stations, the place obtainable, are utilized to the processing. The improved PPP resolution achieves 1-3cm XYZ absolute accuracy in lots of components of the world.
The identical KlauPPK software program workflow applies, to synchronise digital camera occasions, apply lever arm corrections, handle coordinate programs and geoids, apply website localisations, seize floor factors, and so forth. As an alternative of selecting a base station, which needs to be inside 20 miles of the positioning, or establishing an RTK radio hyperlink, customers with an energetic KlauPPK subscription can course of a excessive accuracy trajectory, anyplace, with out some other inputs. The annual subscription permits limitless processing of information from KlauPPK .
Enterprise drone operations can now deploy a number of crews anyplace on the earth and apply one easy constant workflow to the operation with out concern for the ‘survey’ points of sourcing and managing base station information, whether it is obtainable in any respect.
That is highly effective new know-how and might be a differentiator for these at the forefront of UAV options.
