The solution may be LS telecom’s cost-effective antenna radiation pattern measurements using Remotely Piloted Aircrafts.
LS telecom said it “carries out these measurements by means of remotely piloted aircrafts (RPA), which include a measurement and sensor system on board. The RPA circles the antenna and measures the radiation pattern in the horizontal and vertical planes at predetermined altitudes and distances from the antenna.”
TS telecom offers the antenna measurement as a turnkey service “from the preparation and calibration of the remotely piloted aircraft (RPA), to the in-flight antenna performance measurements and the delivery of the results. The deliverables consist of the horizontal (HRP) and vertical radiation patterns (VRP) and effective radiated power (ERP) per transmission service.”
The RPA (which could also be called a drone) flies a pre-programmed flight path that’s accurate on all axes. Measurements can be conducted close to the antenna mast or at greater distances. In case you are worried about a rouge RPA/drone, LS telecom said there are several safety features embedded in the operational and navigational systems in the RPA system, including a “return to take-off point” should the remote control fail.
