Using Desmos, triangulation can be demonstrated. There are some initialization items that must occur. Visualizing the lines of bearings (LOBs),can quickly show where an emitter could be. Introducing errors or changing angles can also show how easily the data can be adjusted to represent the wrong location.
- [Instructor] Now I am going to…show you how some of this works.…If you go to the link above, I actually…have pre-built a lot of this for you.…You would just need to enable or modify things as you want.…Desmos is a free, or paid version available,…calculator that can do some fun graphing stuff.…There are a lot of sources out there on this.…One I like comes from everything2.com.…It has some good descriptions and easy examples…to follow, which is what I based this off of.…
We need to initialize some points.…Just type in these bits into Desmos.…These are the locations you measured LOBs,…which in order for triangulation to work,…you need multiple LOBs from multiple locations.…Oh, don't forget, under options put it in degrees.…We basically want to create three rays from our locations.…Copy and paste these in.…
For R3, put 0.1.…Zero doesn't work well in the math.…Where the three different rays or LOBs…intersect is where the target emitter will be.…Triangulation is pretty easy, right?…Ha!…Let's make it move around a little.…
