Jammer resistant drone designs spark search for countermeasures
The Russia-Ukraine conflict has driven another stage of evolution for drones and the counter measures to defend against them.
Strabag orders KlauPPK system
KlauPPK has supplied its high precision drone surveying technology to Strabag for construction services support.
European construction services company Strabag trialled the KlauPPK system deployed on a DJI Inspire 2 UAS with a Klau-calibrated X4s camera. Fourteen control points were placed throughout the 17 hectare test area and surveyed by a ground vehicle. The KlauPPK software was then used to compute the locations in a European geoid model and coordinate system using the available national VRS correction network without running a local base station GPS receiver.
According to the company, the residual errors for all 14 control points partly were in the sub-centimetre area, with a calculated total error of 2.45cm (RSME), which is well beyond the claim of 3cm absolute in X/Y/Z.
Based on this successful trial Strabag has ordered a KlauPPK add-on for an existing DJI-Matrice-M210 copter, and has begun a road construction project with a leased system until the new unit arrives.
