What is the difference between the ellipsoid, mean sea level, geoid, geoid height, and orthometric height — and which one is right? Learn how the ellipsoid elevation your GPS receiver captures relates to the geoid, how to convert between the two so you can start using your data, and why most GPS receivers don't output the orthometric height you rely on.
For iOS and Bluetooth™ to be useful together, an accessory (like the high-accuracy Arrow GNSS receiver) and a device (e.g., a tablet) must support in common one of Bluetooth's standard profiles. A Bluetooth headset, for instances, would use HeadSet Profile (HSP).
