Dynamic dumphfdl wrapper that changes listening frequencies based off of HFDL activity.

• Front-end UI
• Derive bands from SPDU via provided system table config instead of current shortcut.
• Allow more dumphfdl command line argument passthrough
• Allow more arguments to be configurable via environment variables
• Use Airframes SPDU API to immediately hone into active frequencies
• Use "heard from" data from aircraft's HFNPDU messages

First, install a stable Rust toolchain. Make sure the cargo command is in PATH environment variable after completion.

Second, clone this repository:

  git clone https://github.com/airframesio/hfdl-autopilot

Third, compile and build hfdl-autopilot:

cargo build --release  

hfdl-autopilot --bin /usr/local/bin/dumphfdl --sys-table /usr/local/etc/systable.json -v --port 7270 --chooser tracker:target=Albrook --timeout 150 -- --soapysdr driver=airspyhf --output decoded:json:tcp:address=feed.airframes.io,port=5556

Schedule when band changes should occur.

--chooser schedule:7:00=21,19:00=8

Only stay within a single change and never change. This is the same as running dumphfdl normally. The only advantage this offers is the automatic grouping of frequencies within a 256-384 KHz "bands".

--chooser single:band=13

Change bands once inactivity timeout invokes.

Valid types:

• inc - on timeout, move on to the next highest band; if already on the highest band, move to the lowest in the list
• dec - on timeout, move on to the next lowest band; if already on the lowest band, move to the highest in the list
• random - on timeout, choose a random band that we haven't visited in the last 6 sessions

--chooser rotate:type=random,start=21,ignore_last=8,prefer=21@7:00/10@19:00

Track messages to/from a specific ground station. Move on to a new band if inactivity timeout occurs or we haven't heard a message to/from target for timeout seconds.

--chooser tracker:target=Agana,last_heard_timeout=600

By default, hfdl-autopilot will expose a simple REST API on port 7270. This API allows users to query session state information such as flight position reports (via HFDL link layer), latest ground stations frequencies, and message statistics.
