Likewise, the transmitter radio is a big metal antenna in the TV center that produces a powerful signal and sends them from one end of the earth to another. Interfacing the GPS module to your project is as easy as writing a couple of lines of code. I now realise that was likely the gyro. Stop at the point where the signal strength is maximum. Nonetheless, the two could be dissimilar in shape or appearance. The satellite then increases that signal and brings it to the receiver antenna on the planet. and then calculates its own distance from those satellites. In most cases, you are probably looking for a simple, small-in-one solution where GPS receiver and antenna would be on the same package. For Dual or co-phase installations, use 72-75 ohm (RG-59A/U) coax. You will need a multimeter (preferably digital for ease of reading) with probes, and antenna (s). Then there is a rudimentary map to show your position on it, time, altitude, and speed if you are moving. But I'm guessing a DC ohm meter should.
