# Femtones MINI2 Receiver

[MINI2 Receiver](http://www.femtomes.com/#/MiniII?type=0) is an RTK GPS receiver that delivers high-rate and reliable RTK initialization for centimeter level positioning.
It is intended for applications that require high-precision positioning (e.g. navigation and mapping, etc.).

수신기는 직렬 포트 (UART)를 통하여 PX4에 연결되며, 표준 웹 브라우저를 사용하여 설정할 수 있습니다.

## 배선

The [MINI2 Receiver](http://www.femtomes.com) is connected to a UART on the flight controller (GPS port) for data.
모듈에 전원을 공급하기 위하여, 별도의 12V 전원공급장치가 필요합니다.
12핀 커넥터 핀은 아래와 같이 번호가 지정됩니다.

## 설정

방향 추정을 위해 두 안테나는 같은 높이에 있어야하고, 서로 최소 30cm 떨어져 있어야합니다.
The direction that they are facing does not matter as it can be configured with the [GPS_YAW_OFFSET](../advanced_config/parameter_reference.md#GPS_YAW_OFFSET) parameter.

Configure the serial port on which the [MINI2 Receiver](http://www.femtomes.com/#/MiniII?type=0) will run using [GPS_1_CONFIG](../advanced_config/parameter_reference.md#GPS_1_CONFIG), and set the baud rate to 115200 using [SER_GPS1_BAUD](../advanced_config/parameter_reference.md#SER_GPS1_BAUD).

Once configured the receiver is used in the same way as any other [RTK GPS](../gps_compass/rtk_gps.md) (i.e. with respect to the Survey-in process).

## 추가 정보
