GP-20U7 provides high position, velocity and time accuracy performances as well as high sensitivity and tracking capabilities. Customers benefit from the strength of both companies. Thanks to the low power consumption technology, the GPS receiver is ideal for many portable applications such as PDA, Tablet PC, smart phone etc.
This module sends six National Marine Electronics Association(NMEA) messages in the form of strings. It is standardized with NMEA 0183 https://en.wikipedia.org/wiki/NMEA_0183 . It is slowly being phased out by NMEA 2000 https://en.wikipedia.org/wiki/NMEA_2000. It is also capable of using the UBLOX protocol. The serial configuration needed for the GP-20U7 is:
- Baud Rate = 9600
- Data Bits = 8
- Parity = None
- Stop Bits = 1
- Handshake = None
A typical output will look similar to the following:
