    I'm currently using a Garmin device for my bike navigation. Unfortunately it only support GPS, and from time to time I loose satellites (mountainbiking in the woods).
    I was thinking about buying a smartphone that supports GPS, Galileo, Glonass en Beidou for navigation.
    I have a few questions on this:
    - can all these "providers" be used simultaneously?
    - will it make the accuracy better?

    What is your opinion on this? Would it be a good decision?

    Thanks in advance

    Yes, smartphones that can use GPS + other constellations like Galileo, Glonass and Beidou can use them all at the same time, Yes multiple constellations will make better accuracy

    You are probably losing satellites in tree areas because the receiver in your GPS is not very sensitive, newer GNSS receivers not only use multiple constellations but are also more sensitive so even with GPS only they are less likely to lose signal due to tree cover

    This is a screen from a smartphone using GPS (USA) + GLONASS (Russia) + Galileo (EU) + QZSS (Japan) + Beideo (China)

    A newer smartphone will perform better than an older dedicated GPS, but remember it will have disadvantages such as lower battery life and not waterproof
