Hi
I am trying to build my own gps system with my own coordinates system. The reason behind it is that I need to make it work in a covrrrd area. I need to move an object and I should read it’s coordinates (x,y,z) with great precision.
I can’t rely on a normal GPS as I have no coverage.
Any ideas?
I truly appreciate your support.
Unless you intend to launch a new satellite system, you and me plus every other GPS user is constrained to using what is available. However there are others, including uber, who have found GPS implementations wanting. From the Uber engineering blog
Since the (literal!) launch of GPS in 1973, we have advanced our understanding of the world, experienced exponential growth in the computational power available to us, and developed powerful algorithms to model uncertainty from fields like robotics. While our lives have become increasingly dependent on GPS, the fundamentals of how GPS works have not changed that much, which leads to significant performance limitations. In our opinion, it is time to rethink some of the starting assumptions that were true in 1973 regarding where and how we use GPS, as well as the computational power and additional information we can bring to bear to improve it.
While GPS works well under clear skies, its location estimates can be wildly inaccurate (with a margin of error of 50 meters or more) when we need it the most: in densely populated and highly built-up urban areas,
The other possibility is developing your own positioning system that does not rely on satellites for use in a specific (inverse square law between accuracy and size of area to be covered) but then wouldn't be gps...
Instead of GPS, which uses an array of satellites orbiting the earth, and at very best has an accuracy no better than 10 feet, it sounds like you need to use something similar to virtual reality sensors that are able to detect location within a defined area. However, I thinks that's way beyond the limited computational power of arduino.
Hi Waelk,
What size object are you positioning and what coverage area do you need. Also, when you say “great precision” are you talking about meters or millimeters?

Boeing uses such a system to assemble their airplanes from the various sub-assemblies. Reporting mm precision.

Any ideas?
Pozyx will work.
