Professional drones

Professional drones also known as UAVs, SUAs are drones used for carrying out professional activities or supporting them. A professional drone can in fact be used for aerial photogrammetry, for 3D mapping, for precision farming, etc.

Each drone-UAV, therefore in relation to the type of activity to be carried out, must have characteristics or technical specifications that make it suitable for that activity.

Here, therefore, that knowing how to interpret the technical specifications is fundamental for the choice of a professional drone.

Professional drone – The specs

We must first highlight that acquiring the technical specifications (or specs) of a professional drone is not always easy. Furthermore, not all manufacturers report the same specifications. For example, the manufacturer X can report the maximum tangency quota for his UAV, but the manufacturer Y can omit this information in the technical data sheet. Get ready for this! However, the 4mydrone website shows for almost all drones the technical data sheets complete with all the information that makes it possible to compare the different models of professional drones.

Basic specs of professional drones

In the data sheets of professional drones, we can find different specifications-information. Among these, for a good choice of professional drone, it is important to know how to identify the basic ones which are:

  • Flight time: indicates the maximum flight time with a battery and is shown in minutes;
  • Maximum flight height: the maximum height that can be reached by the drone indicated in meters;
  • Maximum flight distance: the maximum horizontal distance that can be reached by the drone indicated in km;
  • Max payload (weight) transportable: the maximum transportable weight indicated in grams o Kg;
  • Max wind resistance: ie the maximum value in m/ s of wind (constant or gust) sustainable by the drone in flight.

The values given by the professional drone manufacturer for the above parameters are very important as they allow to identify if that type of professional drone is suitable for the activity that we have to carry out.

For example, if we want to carry out aerial photogrammetry with the drone, it is important that the drone has a long flight autonomy, which reaches a suitable tangent altitude for the survey and that it can mount a payload (camera) of an appropriate weight for aerial photogrammetry.

Needless to say that the presence of positioning systems on the drone such as GPS, Glonass, Galileo, RTK, etc., are to be considered fundamental for a professional drone and are part of the basic specifications.

Additional specs professional drones

In addition to the basic specs, when choosing a professional drone you must also carefully evaluate the additional specs of the drone relating to speed, namely:

  • max speed: that is, the maximum horizontal speed of the drone expressed in m/s or Km/h;
  • ascending speed: (valid for drones with rotor): ie the maximum vertical speed expressed in m/s;
  • descent speed: (valid for drones with rotor): that is, the maximum descent speed of the drone in m/s.

These specifications, important but not fundamental, identify performance capabilities which in most professional fields are not strategic.

Payload specs

As you well know that he uses professional drones, the payload is the real “core” of the professional drone. The payload, be it a video camera for filming, a multispectral camera for precision agriculture, or a laser LIDAR for surveys, is in fact entrusted with the most delicate task and in the economy of the drone + payload system is generally the most expensive.

Regardless of the performance capabilities of the payload, which are not the subject of the article, it is well to be able to read the specifications of the paylaod, in relation to the usability of the latter with the professional drone identified.

So the first parameter to evaluate is the compatibility of the paylaod with the professional drone model. In fact, these drones accept only certain types of payload and vice versa.

Consequently, the weight of the paylaod must be evaluated and must be congruent (less or equal), with the max payload transportable by the drone.

Another fundamental data to be able to read from the paylaod characteristics is the paylaod feeding method. In other words, it is essential to know if the paylaod is self-powered and the power supply is included in the weight of the paylaod itself.

For more information on how to read the technical specifications of professional payloads, we recommend reading the article “Professional Payloads – Reading the specifications” of the 4mydrone Blog.

Conclusions

The technical specs are the identity card of professional and leisure drones, but I assume a fundamental importance in the case of choosing a professional drone. Knowing what the basic technical specs are and evaluating them together with the important specifications for a paylaod means having the right knowledge to make a careful choice for your professional drone-UAV.
