If you are experimenting with monitoring fleets, high-altitude scientific experiments, or any kind of project requiring localization of devices, the MKR GPS Shield will offer you the functionality you need, and it is plug ‘n’ play!
The MKR GPS Shield is based on the u-blox SAM-M8Q GNSS (Global Navigation Satellite System) module. It is meant to be used on top of boards in the MKR format, but thanks to its Eslov connector, it is also possible to hook it up to any board having that kind of connector available using a cable.
This module is designed to operate with different positioning services concurrently. It receives and processes the signals from GPS, GLONASS, and Galileo. It interfaces with Arduino boards either through a serial interface when used with headers and put on top of an MKR board, or through an I2C interface and a dedicated ESLOV cable supplied as a bundle.
Configuration Commands and Backup
The GPS module can be configured via special commands. We have included an onboard battery holder for the system to keep the configurations made via software. This can be convenient when e.g. changing the operation mode of the GPS to 1g, something common in high altitude experiments, where specific settings away from the default ones are needed for the device.
Another example is the use of Galileo’s localization option, which is disabled by default but can be enabled by sending a configuration message (UBXCFG-GNSS) to the receiver. You can find a detailed description of all of the commands in the protocol here.
Our Arduino_MKRGPS library handles the two different interfaces and offers a consistent set of APIs designed for full usage of the GPS-acquired information
