It is a complete GPS Module that is based on the Ublox Neo 6M. This module uses the latest technology from Ublox, allowing to give best possible positioning information.
It also includes an external GPS Antenna and a UART TTL connections. This module has on board rechargeable li-ion battery so that the module can hot start in most cases and can obtain the GPS lock faster.
The UBlox NEO 6M GPS Module Engine is very good, and comes with a binary output of very high precision.
It is also suitable for indoor applications due to high sensitivity. The on board battery also allows for storage of configuration settings in EEPROM.
It allows for flexibility in mounting GPS Module, allowing the antenna to be positioned such that it will always face the sky for best performance.
