In our lab we detect a lot of reflections and error resulting from these reflections (flat surfaces etc). Depends on the materials involved. where I am for example there are raised floors and lots of metal. Wooden or natural coverings will have drastically different effects but that's probably outside the scope of this thread. The more clear your view to the sky the better. Michael has spoken clearly in the past on multipath for example and the effects there. Just remember this is all radio at it's core. Anything you learned about radio signals in your sixth grade science class (back when you got a great education from the public schools, pointing at certain members of this list) applies here. So when you block a signal you render it less effective in any form. Both the Holux and US-Globalsat sites have good information about the basics of GPS which apply to all tools including Sindero. The Government also maintains both highly technical and consumer oriented information. It's an amazing technology!

Thanks Alex that makes sense. for anyone who has been able to get a signal indoors, how did it do could use really use it as affectively as you can outside. ----- Original Message ----- From: "Alex Parks" <mehgcap@xxxxxxx>

Gps relies on satellites, whose signals are blocked by buildings. You may be able to pick up a signal indoors but there is no way you will be able to navigate a building with it. A jump drive would work but I recommend a cf or sd card which can be left in the unit more easily and does not stick out. The maps come on an 8gb card, but you can get anywhere from a 1gb to 16gb. What size you get depends on how many maps you will need at a time and which maps they are--the Maine maps are much smaller than the California maps.

Have a great day,
Alex

Hi.  Does the braille note gps work indoors yet or is that being
planned?
Also, if I get a jump drive for my m-power , can I save the maps
for the US
on to that drive or what kind of device are they on like a cf
card or an sd
card? I know you can get those little drives with several gigs
have a friend
who just got a 3 or 4 gig one so that is what made me wonder and
if I can,
what gig should I go with just to be sure there is enough space?

Hi.  On the Voice Sense I put in Sendero as the virtual position
and the
Lighthouse as the destination.  It showed that the destination
was 64.37
miles southwest from Sendero.

The Voice Sense plays progress tones, but I don't think they are
three
seconds apart.  I created the route using two slightly methods.
The first
was using the micro hard drive CF card with the whole West of
the US
loaded.  The second test was with only the California maps
loaded in the
flashdisk of the Voice Sense.  In both cases the result was the
same.
Creating a vehicle route took 57 beeps.  The route had 364
waypoints.  To be
honest, this is longer than what I would have thought.  At least
when I've
created many routes in Denver, Chicago, and Fort Wayne, 60 or so
mile
routes do not seem to take as long, but I don't know if POIs or
map areas
have something to do with this.

So, there is the Voice Sense side of things.

If we wwant to figure this out we can run a test.  Let's say we
just have
the maps for California loaded and create a route from Sendero
Group to
the LightHouse and see what the
difference in speed is.  Raul, I am not sure if there is some
progress
tone on the Sense Nav.  On the Sendero GPS, there is a swoosh
that occurs
every 3
seconds to indicate some progress.  Starting: Sendero Group
11188 Maple Lane Davis, CA Ending: LightHouse
214 Van ness Ave San Francisco, CA Could someone perform the
route
calculation on the BrailleNote and someone on the VoiceSense? We
then can
compare notes.  It might be faster on the VoiceSense as Alex
suggested as
there is more processing power and RAM on the VoiceSense.  There
are many
variables that aren't accounted for, but this is just a general
comparison.  Kevin -----Original Message-----

Isn't the chip in the Braille Sense faster? Maybe someone from
sendero
could
tell us if route calculation is noticeably faster.

Hello Eric.  I'd be happy to comment on the Voice Sense side of
things
although I'm not sure how much my comments will mean since I've
only
used the Voice Sense and not the Braille note.  The things i can
comment
on are mainly things which I've seen from reading other user
experiences, but none from me personally.

Eric Brinkman said the following on 12/13/2007 11:26 AM:
Hi,

I am curious whether anyone who has used both the BrailleNote
GPS and
the Voice Sense GPS can comment on any differences between the
two.
Thanks in advance.

Eric
