Default Google to provide raw GPS measurements

wrote:
An article in the July 2016 GPS World magazine states that raw GPS
measurements will be available to apps in the Android N operating
system, which will be released later this year. This means you can
get pseudoranges, doppplers, and carrier phase from a phone or
tablet!

That is extremely interesting, it would seem to make it possible to use
any pair of Android N devices as a base+rover setup for cm (or least
sub-sub-meter) resolution measurements. (The lack of a proper antenna
will probably be the real limiter.)

With an app which stores all the raw data you should also be able to do
post-processing with a single device plus some reference station data.
