Hello everyone.
The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.

Does Hololens has GPS/GNSS module inside?
Does Hololens has GPS/GNSS hardware module inside?
If yes, anyone knows the details model?
If not, how does Hololens do the positon fix function ,using sensor or realtime graphic processing position method?
Thanks!

No. It has no such sensors. Which makes sense: the device is meant to be used indoors and there the GPS reception is poor.
It does all its positioning by use of the 4 gray scale camera's. The data is processed by the HPU and the coordinates, movements and so on resulting from that are given to the CPU.
In practice this means the tracking is really, really fast and accurate, but does require enough light to work. It works in the twilight of the evening but it will not work reliably late at night with all the lights out.

Hi, You can however use IP locational services to assist if you working on mapping.
Actually, the HL does do well in some outdoor situations, but more to the point, GPS, even rough estimates, can help A LOT when picking datasets. Esp if you use a hotspot/tether or access like Comcast or such, which have many same-named access points. I think no GPS sensor is a shame. Not that expensive to have included.
GPS would have killed the battery faster. I think it was a good decision to leave it out on the initial release, and add it back in when they've refined the device more.
In the meantime, I've used the below for fairly accurate results.

It definitely needs GPS. This is one one of the letdowns that could have opened a whole class of outdoor applications. GPS plus head direction tracking with head locked holograms could be huge. But no. Not everything needs holograms locked to scene surfaces. So we're pretty much stuck inside. :-(
IP location is almost worthless.

Let me know if it helps anyone out.
