The problem with airspeed sensors

Airspeed sensors have been a major concern for both manned, and unmanned aviation alike. Yet almost every fixed wing or VTOL vehicle is dependent on it. So what is wrong with these sensors and why are they used?

How an airspeed sensor should work

A standard airspeed sensors consists of a pitot tube, a temperature sensor and 2 pressure sensors. The pitot tube has 2 ports (holes), one at the tip (like an injection needle) which is called the dynamic port, and…

Livox Mid-40 LiDAR short review

Hi guys! Recently I had a chance to experiment with Livox Mid-40 - a 230 m range LiDAR using rotational Risley Prisms.

I thought I would share my findings with the community in case it can be considered a viable scanning solution!

The first thing to note about this unit is the weight of 710g that could be a blocker for smaller UAVs. The scanning field of view is 38.4° (circular) and the scanning pattern is as follows:…
