I want an alarm when I get near my train station

I have a pocketpc / smartphone with windows mobile and inbuilt GPS chip.

Is there any application that will track my position and give me an audible
alarm when my current location is less than a given distance from a previously
selected position?

The reason is that I tend to fall asleep in the train and want to be woken up
when I am approaching the station where I want to get off the train.

I could use the standard alarm function and have an alarm sound shortly before
the planned arrival but trains can run late, or even early but that's very
unusual.

Using the location I would not even need to research the planned arrival time
- just set it to rouse me 500 or 1000 metres from my destination.

You'd have to leave your phone open on the seat next to you so that it
could track the GPS satellites during the journey. Last time I fell
asleep on a train I woke up to find someone had stolen my phone.

Ouch!

But my cellphone doesn't fold, so I can leave it in its holster when
walking with a GPS Tracker. Safer, obviously.

Inside a train might (probably *will*) be a different issue, however.

My old Qstarz BT-Q818 GPS and/or the Q1000 (I don't recall exactly when
I upgraded) worked well enough in my last couple houses and my current
condo. In my previous-to-current place it worked in my basement office
although it would take several minutes to get the initial fix (and
obviously I can't judge it's moving accuracy in a basement)

Even in my current condo I can typically get a lock sufficient to
pinpoint which wing of the building I'm in from a bathroom on the inner
end (the wall nearest the hallway)

Getting the initial fix can take longer, but once it has a fix it's
surprisingly accurate even in an urban canyon environment it's rarely
more than a couple blocks off.

I don't use it much anymore, but occasionally fire it up attached to the
laptop before a trip (or did, the iPad has virtually replaced both the
GPS and the old laptop. The iPad's GPS isn't nearly as accurate, but
it's "good enough" given the advantages of the form factor)


It's more than sufficient to set a wake-up alarm. It's not necessarily
sufficient to rely on if you're otherwise unable to determine the
station where you're currently located though.

I should have mentioned that my house has a flat
metal roof, thats close to the situation with a train.


You can however see if it gets the direction of movement right etc.



I dont get any satellites showing at all in side my house.

With the Nokia N95 either, and with the separate gps receiver.



anyway.


Not it if the alarm goes off a KM late.


It wont work with ours anyway, because they are all underground.
