Some phones have barometers for GPS (not sure how that works) so I wouldn't be surprised to see that. Perhaps Google are building their own weather center out of human drones.
- cvs268 13y agoBarometers measure pressure. And knowing the pressure at your location(assuming its atmospheric pressure and that U are not in a sealed chamber) one can calculate the altitude(mean height above sea-level). This further improves the accuracy of your location when using GPS to calculate Latitude and Longitude.
- joshu 13y agoGPSs measure altitude too. Do you have any idea how a GPS works?
- revelation 13y agoIt's used for a quick fix and no you don't have altitude unless you have enough satellites.
- Isamu 13y agoThe Galaxy Nexus uses the Bosch BMP180 barometric pressure sensor. This means you can get a faster GPS location with fewer satellites. That's the main motivation for it. http://www.bosch-sensortec.com/homepage/products_3/environmental_sensors_1/bmp180_1/bmp180 http://www.bosch-sensortec.com/homepage/products_3/environme...
