{% endcontent-ref %}
{% endstep %}

{% step %}

### Connect Antenna to Aircraft and Module

Install the Antenna per the manufacturer instruction
{% endstep %}

{% step %}

### Setup & Power On RS2 Base Station

Assemble the RS2 base station per manufacturer instruction.&#x20;

Verify base station fix type being used:

* Self-Survey for **Relative Accuracy**.
* Known location or built in NTRIP for **Global Accuracy**.

{% endcontent-ref %}
{% endstep %}

{% step %}

### Connect Sentera Ground Radio to RS2

Connect the ground radio to the RS2 using a USB-C to USB-C cable.&#x20;
{% endstep %}

{% step %}

### Power Up Aircraft&#x20;

Power the aircraft on per manufacturer instruction.&#x20;
{% endstep %}

{% step %}

### Verify Session Start & Fix Type

Wait for the sensor to boot and start a session. The session start on the sensor is indicated by the LEDs on the sensor being solid green.&#x20;

Verify the GPS fix type using the external LED on the module or use the camera indicator icon in the upper right-hand corner of IGC.&#x20;
