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.

P
= PilotAware
M
= MLAT i.e. Mode-S
A
= ADSB
l
shows that the reception is local i.e. being picked up by this ATOM GRID station
r
shows that the reception is being sent from another local ATOM GRID station
Please check that you are receiving PilotAware transmissions, Flarm transmissions and ADSB
transmissions within 30 Km.
MLAT derived traffic will only be detected when the MLAT feed is available.
Other Columns in the Home Page
Column 4 shows the age of the received transmission useful for MLAT data
Column 5 shows the ambiguity of the MLAT data useful for MLAT data
Column 6 shows the distance of the received aircraft from the ground station
Column 7 shows the altitude of the received aircraft. G (GPS) Q (BARO)
Rebroadcast
When a FLARM target is detected its latitude and longitude will be re-broadcast.
When an MLAT target is detected then its latitude and longitude will be rebroadcast
Re-broadcasts will only happen if there is a PilotAware unit in the area to pick it up. This
minimises the amount of bandwidth used. If there is no one there to receive transmissions
we will not send them.
Column 8 shows you the detail of the PilotAware equipped aircraft that is enabling and
requesting the uplink.
Please note as the ATOM is primarily for GA aircraft use, the altitude reported on the home
page is limited to 12000 ft ie FL120. This filter declutters the commercial air traffic operating
above this height which is of no interest to the home page. The Virtual Radar screen is
however given information on aircraft at all heights and its display can be easily configured
for convenience.
