Template: dump1090-mutability/auto-start Description: Start dump1090 automatically? dump1090 can be started automatically via an init-script. Otherwise, the init-script does nothing; you must run dump1090 by hand. . You can modify the options used when automatically starting dump1090 by running "dpkg-reconfigure dump1090-mutability" as root, or by editing /etc/default/dump1090-mutability. Type: boolean Default: true Template: dump1090-mutability/run-as-user Description: User to run dump1090 as: When started automatically, dump1090 runs as an unprivileged system user. This user will be created if it does not yet exist. Type: string Default: dump1090 Template: dump1090-mutability/log-file Description: Path to log to: When started automatically, dump1090 will log its output somewhere. This log will contain any startup errors, and periodic statistics reports. Type: string Default: /var/log/dump1090-mutability.log Template: dump1090-mutability/rtlsdr-device Description: RTL-SDR dongle to use: If you have only one dongle connected, you can leave this blank. . Otherwise, you can provide the serial number (more reliable) or device index (first device = 0, but the ordering is unpredictable) to choose a particular dongle to use. . To run dump1090 in "net only" mode, specify the literal word "none". Type: string Default: Template: dump1090-mutability/rtlsdr-gain Description: RTL-SDR gain, in dB: The tuner gain used by dump1090 can be provided as a value in dB, or "max" to use the maximum gain available, or "agc" to use the tuner's AGC to control the gain. If unsure, choose "max". Type: string Default: max Template: dump1090-mutability/rtlsdr-ppm Description: RTL-SDR frequency correction, in PPM: The oscillator in each RTL-SDL dongle is not perfectly accurate. You can choose a correction factor, in parts-per-million, to correct for this. The correction factor varies from dongle to dongle, and also varies with operating temperature. You can find a suitable value with "rtl_test -p" or "kalibrate". If you don't know the value for your dongle, choose 0. Type: string Default: 0 Template: dump1090-mutability/decode-fixcrc Description: Fix detected CRC errors? dump1090 can fix unambiguous single-bit CRC errors detected in received messages. This allows weaker messages to be decoded. It can slightly increase the rate of undetected errors, but this is not usually significant. Type: boolean Default: true Template: dump1090-mutability/decode-lat Description: Latitude of receiver, in decimal degrees: If the location of the receiver is provided, dump1090 can do local position decoding in cases where insufficient position messages are received for unambiguous global position decoding. Type: string Default: Template: dump1090-mutability/decode-lon Description: Longitude of receiver, in decimal degrees: If the location of the receiver is provided, dump1090 can do local position decoding in cases where insufficient position messages are received for unambiguous global position decoding. Type: string Default: Template: dump1090-mutability/decode-max-range Description: Absolute maximum range of receiver, in nautical miles: If the maximum range of the receiver is provided, dump1090 can filter out impossible position reports that are due to aircraft that transmit bad data. . Additionally, if the maximum range is larger than 180NM, when local position decoding is used (when insufficient position messages have been received for global position decoding), it is limited to only those positions that would unambiguously decode to a single position within the given receiver range. . This range should be the absolute maximum range - any position data from further away will be entirely discarded! Type: string Default: 300 Template: dump1090-mutability/net-http-port Description: Port for internal webserver (0 disables): dump1090 can provide an internal webserver that serves a basic "virtual radar" map. .

Type: string Default: 30004,30104 Template: dump1090-mutability/net-bo-port Description: Ports for Beast-format output connections (0 disables): dump1090 can forward ADS-B messages to other software in several formats. This setting controls the port dump1090 will listen on for Beast ("binary") format output connections. Type: string Default: 30005 Template: dump1090-mutability/net-sbs-port Description: Ports for SBS-format output connections (0 disables): dump1090 can forward ADS-B messages to other software in several formats. This setting controls the port dump1090 will listen on for SBS BaseStation format output connections. Type: string Default: 30003 Template: dump1090-mutability/net-heartbeat Description: Seconds between heartbeat messages (0 disables): If there is no other data sent on a network connection, dump1090 can periodically send an empty heartbeat message to ensure that the connection stays established. This setting controls the interval betweeen heartbeat messages. Type: string Default: 60 Template: dump1090-mutability/net-out-size Description: Minimum output message size: To avoid sending many small network messages, output connections will accumulate data waiting to be sent until either a minimum size is reached or a maximum delay is reached. This setting controls the minimum size, in bytes. Type: string Default: 500 Template: dump1090-mutability/net-out-interval Description: Maximum output buffering time: To avoid sending many small network messages, output connections will buffer data waiting to be sent until either a minimum size is reached or a maximum delay is reached.

A blank value will bind to the wildcard address, allowing connections on all interfaces. . The default value of 127.0.0.1 will allow connections only on localhost, i.e. only connections that originate on the same machine. Type: string Default: 127.0.0.1 Template: dump1090-mutability/stats-interval Description: Interval between logging stats, in seconds: dump1090 will periodically log message reception stats to its logfile. This setting controls how often that is done. Type: string Default: 3600 Template: dump1090-mutability/json-dir Description: Directory to write JSON aircraft state to: As this can be written frequently, you should select a location that is not on a sdcard. The default path under /run is on tmpfs and will not write to the sdcard. . A blank path disables writing JSON state. Type: string Default: /run/dump1090-mutability Template: dump1090-mutability/json-interval Description: Interval between writing JSON aircraft state, in seconds: dump1090 periodically write a list of aircraft, in JSON format, for use by the virtual radar view when using an external webserver. This setting controls the directory to write to. . Here you can control how often the JSON state is updated, which determines how frequently the virtual radar view updates. Type: string Default: 1 Template: dump1090-mutability/json-location-accuracy Description: Receiver location accuracy to show in the web interface: dump1090 can provide the configured receiver location to the web map, so that the map can show distances from the receiver. . For privacy reasons, if you are making the map publicly available you may not want to show the exact location of the receiver. There are three options available to control what is shown: . approximate: dump1090 will provide the receiver location rounded to the nearest 0.01 degree of latitude and longitude. This gives a location that is accurate to within about 0.5 - 1km. . exact: dump1090 will provide the exact receiver location. . none: dump1090 will not provide the receiver location at all; distance display will be disabled. Type: select Choices: approximate, exact, none Default: approximate Template: dump1090-mutability/log-decoded-messages Description: Log all decoded messages? dump1090 can log all decoded messages as text to the logfile.
