CUAV C-RTK
The CUAV C-RTK GPS receiver is an RTK GPS module for the mass market. 一个完整的RTK 系统由至少两个 c-rtk 模块 组成(一个用于基站, 另外一个作为移动站用于飞机上)。 使用RTK，PX4控制器可以获取到它的位置，并且这个位置的精度可以达到厘米级的精度，这比普通GPS提供的位置更加精确。

配置
RTK setup and use on PX4 via QGroundControl is largely plug and play (see RTK GPS for more information).
接线和连接
C-RTK GPS comes with a cable that terminates in a 6-pin connector and 4-pin connector that are compatible with Pixhack v3. 6针连接器提供 rtk gps 的接口, 并应连接到飞行控制器的 gps 接口。 4针连接器是一个 m8n (标准) gps 接口, 可作为第二个 gps(可选)。
:::tip At time of writing PX4 does not yet fully support a second GPS. The 4-pin port need not be connected. :::
The cables/connectors may need to be modified in order to connect to other flight controller boards. The pin mappings for Pixhawk 3 Pro and Pixracer are shown below.
