Windows device's inbuilt GNSS problem ---- Windows Location API & NMEA --- Incompatible
Windows 7 launched over 4 years, however, the two most major maps providers did not provide any app support the Windows Location API, like Google Earth and Nokia Maps OEM licensees (including Streets and Trips), especially Google, sometimes in worldwide's many places just Google Earth/satellitic maps is useful, especially non-cities zone.
The industry's all-purpose standard is with NMEA serial data stream and not a way like the Windows Locator Service. The WLS's information way makes itself difficult to share to other systems, is incompatible.
As yet, at the x86 Windows as we seen of all these external GPS mouses are with the NMEA serial data stream and a virtual COM port, NO Windows GNSS mouse you saw, 4 years!
MS's Vista, Bing, WP, WinRT, these are not successful marker, but the Windows Location API is much worse. Mr. Ballmer Should earlier retire in 2005, not by the time 2014.
But, the PC makers should not be tied a death by MS.
For a GNSS module (BCM4752/BCM47521) no limited to be just a way designable to a Windows sensor API, PC makers can take a flexible design to do it able to be switched dual modes between the NMEA 0183 specs and the Windows location sensor.
It is almost no new parts added on, just new firmware, drivers and a new design.
The design should make an inbuilt GNSS module switchable in between dual working modes:
Mode 1 = an inbuilt USB-based GPS receiver (NMEA 0183)
Mode 2 = an inbuilt Windows GNSS sensor (Windows Location API)
In such a way, you can easier utilize all of the GPS software --- NMEA 0183 specs and Windows Location API.
Also, Can we ask PC markers to offer a update to make up Windows tablet the WLS Sensor changed into an inbuilt USB-based GPS receiver? (That to displace off the old Windows GNSS Sensor way)
For an inbuilt USB GPS receiver is still able to work for the Windows Location API via software, it is just similar to an external GPS. Well then, no problem, never mind of the Windows Location API.
