Hello,
would it be possible to use an hybrid GPS/Galileo receiver instead of
a GPS receiver? Galileo (although it is not available yet, but the
receivers are) will be more accurate than GPS Futhermore building this
into the phone will make that you can use Galileo with the same phone
instead of having to buy something else when you want to use it - the
'usable lifetime' of the phone will be increased.
It's very unlikely that GPS will go away in 10 years.
So, at best you're looking at a slight upgrade - 2-3m error in position
to 1m or a bit less.
For most things, this isn't important.
You're not going to be walking round blindfolded in traffic, using tones
to tell you left/right.
And DGPS can get you better positions with the existing hardware - at
the cost of downloading a couple of hundred bytes.
Currently dual mode chipsets tend to be more expensive.
Eventually - P2 or so maybe it may be a good idea.
