Clarification about the term "GPS Shutdown"

No, but with GPS you're less likely to have to do so.

 

I did previously - ourselves & all our competitors. Tracking of vessels
around the world using GPS & Inmarsat.

Completely irrelevant in our case as we have no stockholders.

Of course - we will shut down until GPS comes back on.

Plenty - 30 or so staff out of work for starters.

24 minutes would be maximum.

Exactly what I asked you, as I am unaware of any workarounds.

For tracking ships remotely.

Read more closely - we are not interested in whether the crew know where they
are - the OWNER ( sitting in his office on the 25th floor of some building in
Singapore) wants to know where all his ships are, just in case something
like...maybe a tsunami or similar...happens to hit. He also wants to be
alerted immediately something goes wrong with the vessel, be it attacked by
pirates or going out of it's designated shipping lane.

Irrelevant in our case. They spend most of their time not near shore.

And then they have to type that information into a system that can transmit
that data back to Singapore - every 15 minutes. It's not going to happen.

Not when they are working around oil fields with cables & pipelines all over
the place.

And our core business. A business that didn't exist before Inmarsat D+/GPS
transceivers became available.

Actually I don't think they did - I'm not even sure it is a rule. I've been
on tens of vessels with AIS sitting in the main navigation area.

Maybe SSAS? That is required to be hidden, but from pirates, not ship crew.

AIS has password protection for certain parameters like vessel name, ship
length & breadth, callsign, etc, to stop tampering by crews, but usually the
installation manuals are left on board & have the password written down.

When did this become a newsgroup moderated by you, already a
self-declared ass?

 

I can keep that from happening at least as long as the
batteries you're carrying will last.

And a second map and compass are not that hard to carry.

If you posit an attack by paper-eating moths, I'm leaving.

 

I recall an account of a man who sailed a converted St. Pierre
dory across the Atlantic to Europe using only a fairly good compass
and a plastic Davis training sextant which cost only about $35 at the
time, some thirty years ago.

Around the same time, I had a cheap Timex watch which lost a
very consistent 18 seconds a month, regardless of my level of
activity. That should be consistent enough drift for navigation.

 

Ideally, in a Catholic church, the front door points west. The
gospel was read from the left side (toward the heathens in the north)
and the epistle was read from the right side (toward the Christians to
the south).

 

Maps can get eaten by paper eating moths before moths can eat a GPS. G'day
mate and don't let the door bang you in the arse as you leave.

 

Well bloke, I haven't seen a bigger dipstick then you. Slag off.

 

Lousy method anyway.

Hang around till nightfall -- it gets considerably easier.

A watch has already been posited for the purpose.

Elementary. Follow the outermost two stars in the Big Dipper
about five times their distancefrom the top of the dipper. If you
didn't know this, why are you discussing mavigation anyway?

It gets more difficult in the southern hemisphere.

Not if you know as little as you seem to know about finding
north.

 

Old ground mate. This thread died. Now I know why they made kill filters.

Which is toward Mecca -- not necessarily due east.

And the dishes can point to anywhere on the equator the
satellite of interest is above. In the central US, this could be well
to either side of south. A better method would be to check the
orientation of solar cells on the telephone kiosks on a freeway. They
should generally point south to get the maximum solar radiation
throughout the day, barring nearby clumps of trees. But if you're lost
on a freeway, I think you have a larger problem anyway.

 

Actually you can then plot an east-west line directly. And it
need not take a whole day, if you've had access to a boy scout manual.

You check the altitude -- before noon the altitude increases;
after noon it decreases.

 

Any chance you'd be willing to provide specific details on
what you've done in practice? So far your arguments seem merely to be
an extended troll -- no more than a child asking, "Why?" after each
answer a parent provides.

 

Obviously it was sited by the same morons who built the
cathedrals right in the middle of the busiest, most crowded parts of
town.

 

Up? And will you have trouble establishing where that is as
well?

Check when you stop to pee. Or do you do that in motion, too?

Because you ask tot goddamned many stupid questions. The pilot
just got sufficiently pissed off.

Of course they're used by both civilians and that subset of
civilians known as terrorists.

Are you going to believe the professionally prepared map or
your own two lying eyes?

And after all this, I have to assume you have the integrity to
use a non-mapping GPS unit. We wouldn't want the device to be misled
by all those unreliable maps within.

 

For all cases -- blub, blub, by blub, blub.

 

As in continuous, heavy, wet tree cover, where a map and
compass aren't fazed..

 

Directly at the sun not required. In any case, when very
young, I looked at an eclipse long enough to get a burn on my retina.
It took a considerable length of time.
