I don't know of any personally, but I'm going to say probably not. If you're looking for dual band / GLONASS + Beidou support high grade receiver, you're typically looking into the $1000-$10,000 area.
The best I've seen in consumer space so far is (surprisingly) the iPhone 5. Full AGPS and GLONASS support, which is better than most Android phones.
Ultimately, I don't know if I can give you explicit advice on the matter, but I would suggest you search for some way to integrate something such as an IMU into your navigation system, if possible. A properly implemented dead reckoning plus GPS is usually pretty hard to fool, as one of the systems will drop errors as soon as something starts to go wrong. However, getting the proper integration might cost you more than you're willing to pay, so it may just be in poor taste for me to even bring it up.
- toomuchtodo 13y agoLots of phones support GPS & GLONASS together: http://en.wikipedia.org/wiki/List_of_smartphones_using_GLONASS_Navigation http://en.wikipedia.org/wiki/List_of_smartphones_using_GLONA... What we should be doing is replacing $1 GPS receive chipsets in phones with procession positions chipsets, and taking advantage of CORS reference stations (http://geodesy.noaa.gov/CORS/ http://geodesy.noaa.gov/CORS/) for sub-centimeter positioning.
