CUAV C-RTK

CUAV C-RTK 是CUAV面向大众市场推出的 RTK GPS模块。 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设置和使用在px4上通过 QGroundControl 很大程度上可以即插即用 \ (请参阅RTK GPS 更多信息)。

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. The 6-pin connector provides the interface for RTK GPS, and should be connected to the flight controller's GPS port. The 4-pin connector is an m8n (standard) GPS interface that is intended for (optional) use as a second GPS.

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.

Pinout

The C-RTK GPS pinout is provided below. This can be used to help modify the connector for other autopilot boards.
