Abstract
With the help of a GPS receiver (e.g. GY-NEO6MV2, ublox 6m), the long-term position can be calculated. Therefore, the GPS position values will be averaged.
Currently, GPS is used
- to receive current date and time
Wiring:
GPS TX (3.3V compatible) -- Arduino RX GPS RX (3.3V compatible) -- Arduino TX GPS VCC -- Arduino VCC 5V GPS GND -- Arduino GND
Visualization of GPS data
GPS data (course, speed, position etc.) can be plotted by pfodApp:
GPS error
Typical GPS error is 2-5 meters (at a sample rate of 1 Hz). As this is not sufficient as a replacement for a perimeter wire, GPS can only be seen as an extension or for global navigation (navigation from one lawn to another lawn) or to improve the result of a sensor fusion.
