Connecting GPS
|
|
==

|
|
|
Upon connecting GPS, the following possibilities appear:
|
|
|
|
* The copter can remain at the same point when flying outside
|
|
* Autonomous missions may be programmed in the QGroundControl application
|
|
* Flying may be performed by global points in standalone mode using the [simple_offboard](simple_offboard.md) module.

Connection
|
|
---
|
|
|
|
The GPS module is connected to "GPS" and "I2C" (compass) connectors of the flight controller.
|
|
|
|
If GPS is connected, magnetometers are to be re-calibrated in the QGroundControl application via a [Wi-Fi](wifi.md) or USB connection.
|
|
|
|
Next, GPS is to be enabled in parameter `EKF2_AID_MASK` (when EKF2 is used) or `LPE_FUSION` (when LPE is used). When using LPE the weight of the magnetometer should be more 0 (`ATT_W_MAG` = 0.1).
