The LS20031 global positioning system (GPS) receiver module from Locosys receives GPS data on up to 66 channels and outputs the data in more than 6 different National Marine Electronics Association (NMEA) GPS sentences to a TTL-level serial port at a rate of up to 10 Hz. Since the GPS module has an integrated ceramic antenna, you don’t need to buy an external antenna or worry about the many different antenna connectors. The module can typically acquire a fix from a cold start in 32 seconds, and, by saving information about the satellites it was last connected to, the LS20031 can acquire a hot-start fix in less than 1 second.
