Data log:
FDRM is able to keep and store up to 100,000 positions. Each position is detailed as:

  • UTC date
  • UTC time
  • latitude and polarity
  • longitude and polarity
  • altitude
  • speed
  • direction
  • N. of active satellites used to get position

After the first 100K points the FDRM will overwrite old data (FIFO)


Discrete Inputs:
