Simple Tracker Enhancements

Some ideas:

  • Assisted GPS A-GPS enables a faster time-to-first-fix (TTFF) for the GPS modem. Use A-GPS to improve your tracker time-to-first-fix.
  • Predicted GPS (P-GPS) provides up to two weeks of predicted assistance data to the device. It enables a faster time-to-first-fix (TTFF) for the GPS modem. It also offers power saving by reducing the frequency of requesting new assistance data. Use P-GPS to improve your tracker time-to-first-fix and reduce its power consumption.
  • Make your tracker work indoors. GPS does not work inside the building as it is impossible to get a GPS signal indoors. Modify the code to trigger Cell-Based location services when the GPS modem fails to get a fix. You could use either Single-Cell LTE Location(SCELL) which gets the location of the closest cell to the tracker (accuracy 1000m) or Multi-Cell LTE Location(MCELL) which searches for all nearby cells to the tracker and triangulates it (accuracy 300m)
  • Control the frequency of tracking remotely through CoAP. Create another CoAP resource on the server and program your nRF9160 DK or Thingy:91 to observe this resource and update the tracking frequency accordingly.

We have several samples in our SDK that show you how to use A-GPS, P-GPS, SCELL , and MCELL
