- Enable GPS yaw fusion by setting bit 3 of [EKF2_GPS_CTRL](../advanced_config/parameter_reference.md#EKF2_GPS_CTRL) to true.
- Enable [UAVCAN_SUB_GPS](../advanced_config/parameter_reference.md#UAVCAN_SUB_GPS), [UAVCAN_SUB_MAG](../advanced_config/parameter_reference.md#UAVCAN_SUB_MAG), and [UAVCAN_SUB_BARO](../advanced_config/parameter_reference.md#UAVCAN_SUB_BARO).
- Set [CANNODE_TERM](../advanced_config/parameter_reference.md#CANNODE_TERM) to `1` if this is that last node on the CAN bus.
- The parameters [EKF2_GPS_POS_X](../advanced_config/parameter_reference.md#EKF2_GPS_POS_X), [EKF2_GPS_POS_Y](../advanced_config/parameter_reference.md#EKF2_GPS_POS_Y) and [EKF2_GPS_POS_Z](../advanced_config/parameter_reference.md#EKF2_GPS_POS_Z) can be set to account for the offset of the ARK GPS from the vehicles centre of gravity.
### ARK GPS Configuration
You may need to [configure the following parameters](../dronecan/index.md#qgc-cannode-parameter-configuration) on the ARK GPS itself:
| Parameter | Description |
| ----------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- |
| <a id="CANNODE_NODE_ID"></a>[CANNODE_NODE_ID](../advanced_config/parameter_reference.md#CANNODE_NODE_ID) | CAN node ID (0 for dynamic allocation). If set to 0 (default), dynamic node allocation is used. Set to 1-127 to use a static node ID. |
| <a id="CANNODE_TERM"></a>[CANNODE_TERM](../advanced_config/parameter_reference.md#CANNODE_TERM) | CAN built-in bus termination. Set to `1` if this is the last node on the CAN bus. |
## LED Meanings
You will see green, blue and red LEDs on the ARK GPS when it is being flashed, and a blinking green LED if it is running properly.
