Following on from last week, we wanted to give the Arduino some love and make a GPS guide for it as well. We use C++ and an Uno R4 (but you could easily use an R3 or even an ESP32), to get our live location with the module. We then bring it all home by combining it with a magnetometer and OLED screen to build a nifty little project that gives us distance and direction to any targe location on earth! “How to add GPS to Your Arduino | Add Real-Time Location to Your Project!”
That depends on what your indoors is. We often struggled to get it to work inside of our big metal roofed warehouse, but if we were close to a window we could get our location to about 5 meters of accuracy.
You wouldn’t be able to find your exact location inside the building, but you would probably be able to tell which building you are in if that makes sense.
It is probably going to vary a lot and hard to tell unless it is tested. If you got any more questions let us know!
It depends a lot on your antenna. The smaller rectangular ones (~22mx8mm) pretty much require direct line of sight to the satellites. The larger square ones (25mmx25mm) are much better and will work in many indoor conditions. I have had good success with re-purposed WiFi antennae, although technically they are not properly matched. There are also many ideas around for making your own antenna.
