How can this be, given that (a) VHF ACARS is 'line-of-sight', I am in the UK and some of these plots are in India, and (b) the aircraft can't possibly be in all those positions at the same time, can it?.

Q: Sometimes I can see a string of red triangles spread out across the world.

Don't expect to see a screen full of red triangles within five minutes of running your system.

A: The ratio of ACARS messages which contain position reports, to those which don't, is very small.

Q: Although my ACARS message log is big, I am not seeing many plots on my screen.

A: Yes, please take a look at this video from Nic Storey.

Q: Can I use a low-cost USB TV receiver dongle as a receiver for ACARS?.

Plane Plotter attempts to establish this mode of operation in the sound card and will report an error if the mode is not supported by the sound card, or if the sound card is being used by another application.

A: The sound card must be capable of operation at a 48 KHz sampling rate and of yielding a 8-bit mono result.

Details for the RPi are here and for the PC here.

There is now a program available for the Raspberry Pi which allows simultaneous decoding of multiple ACARS frequencies using the low-cost RTL dongle. Traffic appears to be evenly shared between all four frequencies, so if you have the facility to scan them all, then do so.

The mode is AM, so use the line, headphone or speaker output, and not from a discriminator tap!. * See ChangeLog for information on the currently implemented releases of NADCON and VERTCON.There are four main ACARS frequencies for the UK and Europe.

Orthometric Height Height Transformations (VERTCON).

Latitude,Longitude,and Ellipsoid Height Transformations (NADCON).

State Plane Coordinates, NAD 27 (GPPCGP 2.0).

State Plane Coordinates, NAD 83 (SPC83 2.1).

Universal Transverse Mercator Coordinates (UTMS 2.1).

NCAT incorporates the capabilities of the following NGS computer programs, which originally were stand-alone products: Only orthometric-to-orthometric and ellipsoidal-to-ellipsoidal height transformations are currently possible in NCAT. Please note that, although either orthometric or ellipsoidal heights can be used as inputs to NCAT, at this time NCAT does not convert between orthometric and ellipsoidal heights. NADCON and VERTCON provide local error estimates for each transformation, and do not support transformations which are outside the boundaries of the supported areas (generally, CONUS, Alaska, Hawaii, Puerto Rico and the US Virgin Islands, American Samoa, and Guam and Northern Mariana Islands). Transformations are provided for a wide range of frames/datums and regions in the National Spatial Reference System.

NCAT currently uses NADCON* to perform three-dimensional (latitude, longitude, ellipsoid height) coordinate transformations and VERTCON* to perform orthometric height transformations. For coordinate conversion, NCAT allows conversion between lat/long/height, SPC, UTM, XYZ, and USNG systems. NGS Coordinate Conversion and Transformation Tool (NCAT) allows users to easily convert between different coordinate systems and/or transform between different reference frames and/or datums, in a single step.
