Examples

Now let's take a closer look at the basic GNSS position example included in the SparkFun u-blox GNSS Arduino Library.

Example 1 - Position, Velocity, Time

The first example in the library demonstrates initializing the SAM-M10Q (or any other supported u-blox module) and then receiving position, velocity, and time data from the module. Open the example by navigating to 'File' < 'Examples' < 'SparkFun u-blox GNSS v3' < 'Example1_PositionVelocityTime'. Select your Board and Port and click 'Upload. Once the code finishes uploading, open the serial monitor with the baud set to 115200.

For the best results, make sure the SAM-M10Q has a clear view of the open sky. The first time running this example will take ~23 seconds for the module to get a lock onto any satellites. After this initial cold start, the battery on the board will provide power to the hot start circuitry in the module to assist with warm/hot starts during power cycles to drop the time-to-fix down to just one second. This hot start lasts up to four hours between power cycles.
