the circuit takes a little bit of time to lock on to a specific satellite but with a second GPS unit for checking and a few weeks of troubleshooting, the homebrew receiver is up and running.

In a paper published this week in Nature, Google researchers demonstrated they were able to use GPS signal measurements ...

The generic receiver consists of the following functions ... Its function is to receive the GPS satellite signals while rejecting multipath and, if so designed, interference signals. The preamplifier ...

The basic operation of GPS is as follows: signals transmitted from at least three satellites are used to calculate the position of the receiver on Earth (latitude and longitude), and a fourth ...
