Signal Processing Software from COAALast updated 2006 Mar 13
Another of our specializations is in the area of signal processing. Packages include such diverse applications as decoding digital radio messages from aircraft, ships, trains, satellites and emergency locator beacons, software to measure radio propagation for amateur radio operators, software to help in the teaching and tuning of stringed instruments, software to detect meteors using radio, software to generate synthetic ATC instructions for pilot training, and much else.
The software was developed for purposes which may not exactly coincide with your own. The software is made available "as is" with no warranties either expressed or implied as to its suitability for any particular purpose. We hope that you might find it useful and we always welcome constructive criticism. Some of the software requires the payment of a small registration fee. Please only pay the fee after you are satisfied that it does what you want. If you do want to register the software, please do so using our registration web page.
If you have an interest in shipping movements,
this AIS decoder application decodes digital position reports transmitted by merchant
ships on VHF and displays them on a radar-like map display.
ShipPlotter
If you have an interest in aviation, this aircraft position plotting program decodes the digital messages that large aircraft transmit and display their content and plots their position on a radar-like chart. It includes support for ACARS, Mode-S and HFDL position reports.
PlanePlotter
If you have an interest in railways, this decoding program decodes the digital messages that are passed between trains and controllers in several European countries. The protocol is UIC and messages include the train number and things like request voice contact, test, increase speed, decrease speed and others.
TrainPlotter
If you have an interest in marine radio,
this application decodes Digital Selective Calling (DSC) on MF, HF and VHF, Navtex, Rhineland ATIS headers and DGPS beacon data. Where appropriate, positions are plotted on a map display.
DSCdecoder
If you have an interest in radio,
this application helps you to receive aeronautical and maritime navigation beacons. Using a unique combination of Fourier Transforms and Boxcar integration, the program can recover the morse code identification of a beacon signal that is weaker than the background noise.
NDBfinder
This application decodes the digital messages transmitted by EPIRBs (Emergency Position Identification Radio Beacons. The program decodes beacon tests as well as distress messages.
EpirbPlotter
This application decodes the digital messages transmitted by the Orbcomm satellites. Orbcomm is a satellite communication system (www.orbcomm.com) providing two-way data and positioning service to small, portable user terminals in the VHF frequency bands. You can use a simple VHF radio receiver (scanner) tuned to the band between 137 and 138 MHz to pick up the strong signals from these satellites. With OrbcommPlotter you can decode the telemetry and find out the positions of the satellites, their operational status and their uplink and downlink channels. Unlike most satellite signals, there are so many Orbcomm satellites that there is likely to be one within range of almost any spot on Earth at any time of the day or night.
OrbcommPlotter
If you are interested in meteorology, this decoder program displays the telemetry from weather balloon ascents that explore the upper atmosphere.
SondeMonitor
CombiPlotter gives you a way of looking at the data in ShipPlotter, PlanePlotter, OrbcommPlotter and SondeMonitor, all on the same chart or map. If you have one or more of those programs installed, CombiPlotter brings all the data together so you can see when airliners overfly cruise ships or when weather balloons have a near miss with a passing passenger jet.
CombiPlotter
Quite a different signal processing application. This time the Fourier Transform Engine is applied to audio signals with particular reference to the performing arts.
Syntonia
If you are interested in recording
meteors by day or by night, under clear skies or under cloud,
then check out R_Meteor.
If you are interested in
the radio propagation effects of sunspots, you may care to check
out BeaconSee.
If you need to set your
PC clock accurately, by shortwave radio, check out Radio Clock.
If you have a GPS receiver with a serial output, you can set your PC clock with this freeware. GPSTime
If you have a portable GPS
receiver and a Pocket PC (iPaq) you can use your own maps in a moving map display and simulated Surveillance Radar Approach with this application.
