Subject: On Star
From: "Ron" <rgilson@adelphia.net>

Just got an On Star equipped vehicle and decided to check it out. When I
called the operator she located me about 2000 ft north of my actual
location. She made a statement that was my last recorded position. I had
never moved my car from the time I placed the call. Does the GPS data only
get transmitted at the beginning of the call? Can the On Star operator
actually track a vehicle or is it a one shot beacon? Does the GPS and phone
run 24 hours a day? Seems like it must but where does all the power come
from since this must be close to a draw of 1/2 amp. This equals 24 amp hour
every 2 days. Doubt if the car would start after 3 days in the cold north.
Seems like good old APRS tracking draws less power and is more accurate. Of
course I can't have my doors unlocked if I loose my keys. I'm waiting to
hack data and put it on 144.390. Any ideas???
Thanks

Don't think this is only a European thing.... a few hams in the U.S. still
think ham radio has something to do with radio and not just the internet.

Yes... you fix the problem at the source. Kind of a no brainier and I don't
understand why some pushing internet solutions to a RF problem can't see
this. Granted, I can see the internet as a good educational tool, but where
the rubber meets the road, any fix rests solely in the RF domain.

p.s. I love to hear some of your ideas to improve APRS or another alternative
of it. I'm aware of some of the work you guys have done with DAMA and FlexNet
and some of these technologies might make a good fit into some "aprs like'
AVL protocols. The only new thing on the horizon here of late has been
OpenTrak, which is a more concise and accurate AVL (APRS) position location
format. But to the best of my knowledge, it doesn't define the transport
layer, which I am most interested in.

Ron and the Group,
While working for Orange County Emergency Management (NC) we had a vehicle
stolen that had the OnStar system. They were able to track the vehicle in
motion... so it is updating all the time. I think they had to place a
"system call" to the vehicle, though, to get the data flow. So I don't
think they are actively tracking all vehicles all the time. They also have
VERY strict protocols for making such calls. We as the reporting agency
could NOT have the car tracked. The owner actually had to call OnStar and
provide them with information and pass codes in order to start the process.
BTW, we recovered the vehicle 17 minutes after it was taken on I-85... It
worked well! :)

It's in the manual downloadable from their website! Go to:
http://www.gpstracker.com
Note that TigerTronics has a separate domain for the TigerTrack vs their
other products ( SignalLink inteface, Baypac modems, etc) which are at
www.tigertronics.com
Click on "GPS Tracking" in the lefthand frame on the gpstracker home page.
Scroll down the resulting page to "MORE INFORMATION" and click on the
link "Download the complete Installation Manual from our GPS Products
Support Page" .
BTW, maddeningly, the DB9 connector on the TigerTrak is sexed exactly
BACKWARDs from the TinyTrak; i.e. a female connector for direct
connection to a PC, that then requires a cross-over male-male
gender-changer to connect to a GPS in everyday operation! Why?????

I have changed the internal battery. ran it on a seperate battery with the
radio on a seperate battery and my vehicle on a seperate battery. Does not
change the fact that it is a piece of crap. Others on the lists have had
the same problems.

Does anyone know anything about the Icom D-Star radios as far as whether
anyone is using them and for what?
Plusses and minuses?
Or what could we use them for in HAM radio?

As far as I know, they are still vaporware..... (at least in the US).
It is a semi-proprietary protocol developed in Japan for digital radio. A
ham club presentation I recently attended on digital voice (focused mainly
on the AOR digital voice modem for HF) touched on the system briefly.
The presenter says the system was developed by the Japanese government as a
digital land mobile radio standard and then licensed to the ham mfrs to get
some practical experience and working systems into the field.
As implemented by Icom, it consists of a 1.2 GHz mobile transceiver capable
of 128KB/sec data stream (not absolutely certain -- trying to recall a
flyer I saw on the system about a year and a half ago) that can be used for
both voice and data.
In turn the repeater/duplex base station that the mobile communicates with
has an Ethernet output for Internet interconnection, and interconnect to
other similar repeaters via a backbone of 10 GHz digital radio links. The
10 gig links have some sort of IP router-like function embedded so that
digital transmissions received at one site can be forwarded or linked to
desired other sites.

Unless you are using external software to use the D7 in packet mode instead
of APRS mode, leave the destination address as APK002. The D7 uses Mic-E
encoding for positions which uses a variable destination address (see
spec.). The APK002 destination address is used for message packets.
As for the second question, there has been a lengthy discussion on the SIG
about that. My recommendation is RELAY,WIDE2-2 but I am sure others will
chime in with their suggestions.
