re: Re: Moving Targets...This is easy, gentlemen...with Moving Trains in the
Wilderness!..Our specialty...
Hello Shaun, and Global Colleague Ladies and Gentlemen....
This is very easy to do and it is one of our specialties for many years.
Do a web search and you will see. We're always happy to help! We have been
reading through weeks of agony and nice ideas here in this forum, but we've
been totally busy with the INTELSAT Global Operations Representatives 2000
Meeting, just finished, and can only now get to this.We designed the
comprehensive answer to your problem Shaun (and much more) several years
ago; and it is easier and cheaper than many of our friends out there are
thinking. We are happy to reply.
In a nutshell...with a little creativity, and...certainly no cables are
required, too! (Why? Expensive cables 'disappear' to unscrupulous scrap
metal merchants in the wilderness, sold 'by the pound/kilo', and fibre just
gets cut by angry, vengeful metallic cable thieves! High grade copper has
its 'price' after the shiny new insulation is burnt off.)
1. Anybody have a yacht out on the Great Barrier Reef? Install a hybrid
tracking antenna for Ku band on each train at the locomotive or
baggage/goods car where your team is located...in a nice little low dome to
keep things forever clean, and designed to be largely invisible to vandals.
We can show you how to have no RF problems even on electrified
lines....25,000V, for example!
2. Connect it to INTELSAT for a low cost uplink solution and global outbound
connectivity. Want voice, too? A unified Extreme Thin Route VOIP stream in a
very thin, yet quality controlled link does the trick, with on-demand
service.
3. With a little creativity, one can also have a cheap DVB receive-only
signal coming down...and all the Internet speed you can dream of at low
cost. You may be able to use an existing service and piggy back your
downloads on a system already up. We can make suggestions.
4. Again, please forget about Leos and Meos and highly elliptical
orbits...your system doesn't need them. Keep it SIMPLE and Rugged...this is
for trains, remember...and use COTS solutions we have already developed and
anybody can do. Run it all on INTELSAT on the same bird. Keep life simple
and cheap and Carrier Grade. We can work with our correspondent friends at
TELSTRA to help you set it up quickly...get you local names to call, and
such.
5. Please Don't Worry about the few tunnels. We answered that problem years
ago in all its ramifications, including safety of highly valuable, even
nuclear cargoes traveling through the wilderness where there are no radio or
terrestrial links of any kind, by including a GPS system we designed on
Trimble Navigation gear we do...though we can do it on anything you like.
There are a lot of low cost bells and whistles we can add, but Please
remember that you do not 'park' your trains in tunnels, and it only takes a
few seconds to go through them. So, by default, from an operational safety
perspective, if HQ loses your cheapo satellite ID return signal for more
than a few seconds (think of it as a beep with a GPS locator ID included),
your train is in trouble>>>'right there on the map on the monitor'. Remember
every train has a known length...and every tunnel has a known length....and
we know where your train is at all times in the beautiful Australian
wilderness (right?)...and we know the speed your train is traveling at, in
real time....and at what speed your train should be traveling...so we can
set an alarm on the master console (hundreds of miles away) to go off if you
don't come out of *that* tunnel after XX seconds, when your train normally
re-registers by satellite from that nice little Ku band hybrid antenna we
installed! If necessary, we call out the rescue helicopters in seconds to
help you and they can be airborne and en-route to your precisely known
location in a single handful of minutes!
6. We'll lease all the gear to you, too, so, it comes out of taxes and you
can upgrade promptly at the right times, software included...so this is much
easier for the railroad (or other service provider) to justify in the
business plan. Some things on trains don't need to be screwed in for
decades!
Everyone please accept our apologies; no... we are not pitching a
product/service, but please don't hesitate to drop us a line....We would
love to work with you. We developed this comprehensive satellite, wireless,
GPS and wireline answer (and more), many years ago for secure global
transport of trains and ro-ro containers in Central Europe..and for even the
individual sensitive cargoes on various cars/carriages on each train. It
uses Cheap, Commercial-Off-The-Shelf *Everything...and it is "Carrier Grade"
service. Australia was one of the model 'environments' we originally
identified for such a solution as we developed for transport across the
entire Eur-Asian Continental Market Area, particularly starting in Central
and Eastern Europe...where problems can begin, so to speak. It is part of a
comprehensive global secure transport solution we presented to the European
Commission, DG XIII, years ago, in cooperation with the Czech Railways. We
designed it for and with them, as you can read on the web.
