<h2>Introduction</h2>
The top and bottom bars of the device window are described [here](../../../sdrgui/device/readme.md)
The ADS-B demodulator plugin can be used to receive and display ADS-B and Mode-S frames broadcast by aircraft. These contain information about an aircraft, such as position, altitude, heading and speed, broadcast by aircraft on 1090MHz. ADS-B and Mode-S frames have a chip rate of 2Mchip/s, so the baseband sample rate should be set to 2MSa/s or greater.
The ADS-B demodulator plugin can be used to receive and display ADS-B aircraft information. This is information about an aircraft, such as position, altitude, heading and speed, broadcast by aircraft on 1090MHz, in the 1090ES (Extended Squitter) format. 1090ES frames have a chip rate of 2Mchip/s, so the baseband sample rate should be set to be greater than 2MSa/s.
As well as displaying information received via ADS-B, the plugin can also combine information from a number of databases to display more information about the aircraft and flight, airports and weather.

@ -42,13 +40,11 @@ This is the bandwidth in MHz of the channel signal before demodulation.
This specifies the channel sample rate the demodulator uses. Values of 2M-12MSa/s are supported, 2MSa/s steps. Ideally, this should be set to the same value as the baseband sample rate (the sample rate received from the radio). If it is different from the baseband sample rate, interpolation or decimation will be performed as needed to match the rates. However, interpolation currently requires a significant amount of processing power and may result in dropped samples.
2 MSa/s should give decent decodes. Higher rates may be experienced with if your hardware allows it (radio device and processing power). However the higher the rate the more processing power required.

Higher channel sample rates may help decode more frames, but will require more processing power.
<h3>6: S - Demodulate Mode-S frames</h3>
<h3>6: S - Demodulate all Mode-S frames</h3>
Checking the S button will enable demodulation of all Mode-S frames, not just ADS-B. Mode-S frames will not effect the data displayed in the table or map, but can be feed to aggregators.
Checking the S button will enable demodulation of Mode-S ELS (Elementary Surveillance), EHS (Enhanced Surveillance) and MRAR (Meteorological Routine Air Report) frames.

The table displays the decoded ADS-B data for each aircraft along side data available for the aircraft from the Opensky Network database (DB) and aviationstack (API). The data is not all able to be transmitted in a single ADS-B frame, so the table displays an amalgamation of the latest received data of each type.
