Dr. Steve Dimse (K4HG)
first introduced the
APRS
interface to the Internet in
1999.
Is it bad that I demonstrate you a 7 Year Old Technology?
This enabled the feeding of the APRS
information originated from mobile ham station to the Internet. In
this map you can view the mobile hams at the vicinity of VU2NCT
Amateur Radio Club Station. The stations would appear in real-time when they transmit APRS data
on
144.800 MHz to reach the
VU2NCT APRS gateway.
Why javAPRS?
This page uses
Peter Loveall's (AE5PL)
javAPRS [javAPRS
2.7b24 � 2006 Pete Loveall AE5PL] to
demonstrate ham to non-ham communication (Non-hams can only
monitor APRS ham activities using their Internet Browsers) which
definitely have utility during any emergency situation (locating crash
sites, accident sites, traffic jams, position tracking of objects)

Peter Loveall took
over the javAPRS
support from
Steve Dimse,
K4HD.
During the demo,
VU2MUe-9
feeds the real-time RF (Radio Frequency) data via a
KENWOOD radio
interfaced to a computer at VU2NCT and that data reaches you via the Internet
showing its positions & messages on a map (you can in fact track
VU2MUE-9 if you
monitor dedicatedly).
VU2NCT uses
Late Roger Barker's (G4IDE) UI-VIEW to log-in to Rin Fukuda's
(JG1VGX) Tier 2
T2JAPAN APRS server
and then the data is internationally distributed from
T2JAPAN tier 2 server.
VU2MUE-9 can also remotely text message, i.e.
even if he is at a place where there is no Internet
connectivity or where there is no cell-phone network, it could
'text message' you using the radio waves!
In the map above, you can see
VU2MUE-9 moving in the
streets of Delhi when he is

Roger Barker's
(G4IDE) UI-VIEW is a popular Windows based APRS application
used by hams (radio amateurs licensed by the government) all over the
world. UI-VIEW requires a validation from APRS server administrators.
Being a ham I always appreciate others also to become hams so that
they can also use a beautiful software like UI-VIEW and enjoy the
benefits of APRS Technology.
But what if I want to
demonstrate the Amateur Radio APRS capability to a non-ham who does
not have UI-VIEW (or any other APRS applications) installed in his/her
computer?
javAPRS
now gives that flexibility. The map that appears below is an APRS map
accessible by the non hams too. Text messages originated from RF
stations can also be monitored by non-hams which has a utility in
ham radio emergency communication [press 'M' and the read
message at JAVA Console].
