The GP-20U7 is a compact GPS receiver with a built-in high performances all-in-one GPS chipset.

The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.

This 56-channel GPS module, that supports a standard NMEA-0183 and uBlox 7 protocol, has low power consumption of 40mA@3.3V (max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels “all-in-view” tracking, the GP-20U7 is quite the work horse for its size.

Demo

Wiring

The GPS uses a serial connection and needs RX and TX pins.

The library samples using a serial connection with a 9600 baud rate. The library is able to read the latitude, longitude, time, directions, number of satellites, horizontal dilution of precision, Geoidal separation, and antenna altitude above sea level.
