Galileo Gen 2 GNSS is coming

A couple of weeks ago the ESA confirmed that the Galileo satellite constellation is getting a new generation upgrade.

The EU/ESA confirmed 11 new procurement streams which will introduce a variety of changes to accuracy and resilience.

 

Of most interest to sports watch users will be the potential for GNSS accuracy down to 20cm (ahem) which is needed for autonomous cars. However, that service will be provided for free and hence can be used by watches. #Nice

  1. Do you know if that equates to 20cm accuracy at every sampling rate?
    So if watch is set to 1s sampling it will be within 20cm accuracy at every 1s interval?

    For a slower runner at 12min/mi = 2.2m/s that’s almost 10%
    But better news for a 6min/mi runner with 5% accuracy.

    So I imagine that instantons pace will still need a significant amount of watch accelerometer processing.

    1. IDK. i would guess yes but it would depend on the precise tech used in the receiver
      because of the swinging arm there will be processing anyway. your arm varies from stationary to twice your speed when running at a constant speed (i think that’s right).

  2. Is Galileo fully operational now? Could GPS+Galileo result in better watch accuracy in Europe, than GPS+Glonass?

    1. yes i believe its fully operational
      no. it will give increased likelihood of accuracy not increased accuracy per see
      yes i would expect the potential to be better than gps+glonass but it depends on the chip/watch algorithms.

    2. The new models (eg. 955) have a “All systems” option instead of GPS+Glonass, GPS+Beidou, etc, and cycle between 2 systems depending on the actual conditions during the run. So one moment you might be using GPS+Glonass, then 30 minutes later GPS+Galileo, then Beidou, etc (some people can run REALLY far in one session). 🙂

      1. yes i think on the older watches garmin has optimised the GLONASS algorithm the best
        on the newer ones, as you say, all systems appears to be very good and the addition to that of multi-band makes it even better

  3. Garmin nailed it already with the dual band tech. The 1040 shows the capabilities. Remaining inaccuracy most likely wont be fixed due to antenna size constraints in the user devices. I dont expect 20cm accuracy in a watch

    1. antenna is important but so is power.
      spare power capacity means more signal processing.
      Garmin now claim to have spare power. (there’s a quote from one of the execs somewhere)
      i don’t expect 20cm accuracy either but there is still room for some improvement albeit probably unnecessary improvement that wont get.
