back to article French firm notches up 50km unmanned drone inspection flight

A French drone company reckons it has flown a power line inspection drone remotely for 50km (30 miles) – and controlled the aircraft over a public 3G network. Flown to inspect power lines belonging to electricity transmission firm RTE, a drone from Delair Tech was successfully piloted for 50km along a pre-approved route next …

    BVLOS?

    Surely "visual line of sight" is redundant, yes?

      Re: BVLOS?

      Not really. Line of sight in this instance would refer to a straight line between the operator and the drone. The drone may have moved far enough away that it is not visible to the Mk.1 eyeball, but there may still be an unimpeded direct line between the operator and the drone that could be used for control (e.g. radio).

      Well, the expression "line of sight" is also commonly (mis)used for any number of wireless comms, unredundanting* the "visual".

      The French authority involved, on the other hand, is DGAC, not DGCA

          Yeah, that was pretty painful. Well done, OP.

          I saw a new one today, "This will legitimate you"

          Yes, I'm going to nuke it from orbit, just to be certain ->

        Indeed: Direction générale de l'aviation civile

      'Surely "visual line of sight" is redundant, yes?'

      In the context of controlling drones, the key part here is visual, which means that you can see the drone with your eyes. However, whilst you may have control Line-of-Sight to a drone, via its RC link, or in this case via 3G, you may not be able to see it with your eyes because it might be foggy, raining or snowing, or simply because it's night and too dark.

      Perhaps we should retroactively change LoS to stand for Line of Signal, rather than Sight, so it makes more sense when talking about a radio transmission being 'within LoS'?

      Actually, I thought the preferred phrase was "beyond visual range", aka BVR ...

    Anything like my 3G/4G provider and the signals to the drone will be delayed 5min - 5hr whilst some electric monkey takes a tea break.

      That's why they are doing this before August.

    Power lines?

    Not an issue for general Aviation congestion then, no pilot wants near them anyway, so an ideal application.

    There are also ingenious "robots" that can crawl the live grid cables and others that can add fibre to them. Electricity Network operators seem to be creative geniuses. At college I foolishly thought it would be too boring, not realising:

    1) It's not.

    2) You get to change job too often and have too much pressure on the leading bleeding edge of tech.

    Too late to change my mind now.

      Creative geniuses or completely mad as in this case.

        Woah. That drone sure comes in peace.

        Also good against protestors wielding placards with various nonsensical statements.

        That flame-thrower drone was interesting. The operator seemed a bit unsure of how to land it considering his confidence demonstrated in burning off the debris though.

    Well, in my experience, visual range for a UAV is less than 3 km. We routinely operate beyond 100 km with relatively simple microwave radio systems and HD video. So, the only innovation here is to use the cell phone system, but I bet that their video isn't HD.

    An excellent use of a UAV

    I would assume that apart from checking that foliage is not getting too close and for physical damage, it also uses thermal imaging to check for high-resistance joints etc. A great deal of money is spent by utility companies on regular inspections of cables and pipelines by helicopter, so this method should save a fair bit as well.

    Why not equip them with ADS-B and traffic avoidance software?

    Now, this IS Powerline Inspection

    and when repairs need to be done, this is how to do it without turning off the power
