Building and installing a PilotAware ATOM Station to detect and re-transmit glider and
Mode-S MLAT locations and provide Virtual RADAR SERVER December 2020.

†Note the above picture uses low power RTLSDR do
ngles as these fit the available space.
If the RTL-
SDR’s are larger they can be configur
ed to be inserted in other USB sots in the
configuration program described later. If necessary external aluminium enclosures provided
with the dongles should be removed. Many high quality installations are installed in a
bespoke enclosure. A proper job.
Locating and Naming your Site
Before downloading and configuring the ATOM-GRID software, specific information is
required about your site. These are:
1.
The Location
2.
The Name
Location Information
You will need to have the unique location information for your station to hand.
This information can be obtained by going to
htthttps://pilotaware.com/product/rosetta/p://schellenberg.nl/ogn/index-latlon.html
your computer.
When the program opens, (usually at a location in Europe) drag the red marker to the
position of your installation and you will be given the latitude, longitude and the height
AMSL in metres and Geoidsepar. Only use the 6 digits following the decimal point for the
latitude and longitude and remember that the longitude
will be
–
ve. West of Greenwich
.
Make a note of these values for use in configuring the software for your specific location. A
matrix is provided for this on the next page. The Geoid Sphere will be automatically
calculated in the latest software
so you don’t need to input this
.
