HerePro and electromagnetic field limits

Good morning,

I should do a future test work on electrical lines around 200kv and I would like to replace the GPS Here3 with N. 2 GPS HerePro in RTK configuration

I did some studies on electromagnetic interference and we talk about values around 40kv/m as an electromagnetic field and about 200μT of magnetic field

On Herepro technical data sheet I do not find permeability limit values for electric and magnetic fields

Do you have any advice about the limit values of this GPS?

Alternatively, how can I get closer to a conductor without my brave drone being a flyaway in Greenland? :smiley:
