+# 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.).
+
+The receiver is connected to PX4 via a serial port (UART) and may be configured over Ethernet using a standard web browser.

+The following firmware options need to be selected when buying the device:
+
+- 5Hz, 10Hz, 20Hz
+- INS
+- HEADING
+- OBS
+- RTK
+- BASE

+
+## 接线和连接
+
+The [MINI2 Receiver](http://www.femtomes.com) is connected to a UART on the flight controller (GPS port) for data.
+To power the module you will need a separate 12V power supply.
+The pins on the 12-pin connector are numbered as shown below.

+
+## 配置
+
+For heading estimation the two antennas need to be on the same level and at least 30 cm apart from each other.
+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).
+
+## 附加信息
+
+The MINI2 incorporates the following components:
+
+- [FB672](http://www.femtomes.com/#/FB672): Compact, dual antenna, dual frequency GNSS OEM board (delivers centimeter accurate position and precise heading).
+
+  ![FB672](../../assets/hardware/gps/rtk_fem_fb_1.jpg)
+
+- [FB6A0](http://www.femtomes.com/#/FB6A0): Compact, quadruple frequency GNSS OEM board (delivers centimeter-accurate positioning)
