 External GPS receivers can be connected to your mobile device via Bluetooth and used in <MobileAppName /> to achieve higher [GPS accuracy](../gps_accuracy/). 
 
 There are several [extra position variables](../../layer/position_variables/) that can be useful to record when doing the survey with external GPS, such as the GPS antenna height, GPS device name as well as metrics like horizontal, vertical or position dilution of precision (HDOP, VDOP, PDOP).

 ## GPS antenna height
-External GPS antenna is often used on a surveying pole. To obtain the correct ground elevation, it is necessary to subtract the height of GPS sensor above the ground from the measured elevation.

+In Android, there are two ways how to use an external GPS device in the <MobileAppNameShort /> :
 - directly through the app as an external receiver
 - connecting GPS receiver to your mobile device using an app that will provide mock location
 
-It is strongly recommended to use the direct connection in <MobileAppName />. It is easier, quicker, provides more data, such as HDOP and fix quality. The app will report which device is used and take care of reconnecting in case of lost connection. Using mock location should be used only when it is not possible to connect the GPS receiver directly via <MobileAppName />.
