Reception Logger 0.1b
Monday, July 2, 2007, 07:32 PM
The first beta version of Reception logger is ready :)
The GUI is not great but its enough for the first beta.
I hope to continue to add more features such as it saving and reloading old reception data.

The app is now nearly ready. Just need to give it a good run and put into a JAR format and let people play around with the beta.
Outline are included for the maps as well :)

( 3.1 / 758 )AirNav RadarBox Reception Plotting
Monday, June 25, 2007, 04:31 PM
Using the socket data from RadarBox 2007 I have created a application which plots of the reception of aircraft from your antenna. Based on the idea of Polar Diagram Plotter (by Andy (Threemiles) for SBS-1.
Anyhow as you can imagine there is a bit of maths involved in the app such as determining the bearing from your home location. Unfortunately there a few bugs at the moment but getting there.
Reception of my location
The app also creates a outline file which can be loaded into Radar Box as well. Hopefully if I can iron out the maths bug should have a beta to release to anyone with a RadarBox by the weekend :)

( 3 / 787 )ADS-B Antenna
Wednesday, June 6, 2007, 03:28 PM
As mentioned in my last post I was able to get the data out of ANRB. I have decided my first add on would look at two things:
- Distance from Antenna
- Lowest Altitude received
Distance was being done so I could work out how good my line of sight was with the indoor antenna and how line of sight really affects transmissions. Distance of gps coordinates shown below:
sqrt(x * x + y * y)
where x = 69.1 * (lat2 - lat1)
and y = 69.1 * (lon2 - lon1) * cos(lat1/57.3)
Altitude was being done so I could check to see whether I was getting ground signals and whether it was only from specific aircraft on certain days.
Furthermore I linked the above in with google maps. The google API was very helpful and the page below has been produced which I will update every day or so with new entries for the moment.

( 3 / 726 )ANRB Output
Tuesday, June 5, 2007, 02:54 PM
Been working on a java app to connect to the ANRB output to produce some reports on the traffic picked up by ADS-B. After finally connecting to the right port had trouble getting the data as it didn't follow the normal java spec of sending with a new line.
Instead my code had to read each char and work backwards. Anyhow finally getting the following below:
$PTA,20070605125824,4CA2C0,RYR3676,6925,,,0,,51.7968,-0.6261,,,,,,
non,date,hex code, flight no, height, speed, bearing, fpm,?,lat, long,
Using the above data, should be able to make some nice reports. Standby for some apps :)
