Ariadne is good for telling you where you are. Also Sendero Lookaround for
nearest street intersections. For trip planning, MotionX GPS Drive works
quite well.

Hi All,

Really interesting discussion about portable GPS systems. I have an Iphone
4s, so I am wondering what the app would be for me to use as a portable gps?

If memory serves, iPhones, at least at one point, were using a database of
known wifi reference points to enhance navigation. I also have no doubt
cell-based devices can be set to use tower reference points to gain accuracy
as mentioned.

The more open the sky view, the more GPS satellites can be tracked by a GPS
to gain accuracy, but if a device lacks a cellular connection or wifi with
an associated database, options get fewer and fewer, especially for a
handheld unit.

One other item of possible interest (thinking of the taxi comment)-- a built
in GPS in a car will, at least in some cases, use extra tricks, most notably
the antilock brake sensors, to count wheel revolutions and the speedometer
when GPS signals gets lost (especially in say, a tunnel) and estimate
position based on that. It can be pretty accurate because when you turn the
wheels, there is differential between the left and right wheel speeds. (I
think that's called the yaw rate.) That trick won't work so well when
someone is walking with a handheld. I believe many portable car units will
similarly assume continued constant velocity at least for a short time upon
signal loss. I have no idea what a Trekker can do in such a situation.

Here in New York city, when I was wanting to buy a GPS device, an
organization conducted a demonstration of the Trekker Breeze. It
misidentified nearby streets and couldn't estimate the distance to
intersections. I was left with a sense that it doesn't pick up the
satellite signal in an environment of tall buildings. I think it's a
question any city resident considering buying a Breeze might look into
first. A friend has used the iPhone (I believe 4S) in Washington D.C. with
more success, so perhaps the app designed for it is a better bet in an
environment. This is hardly a good sample size, but the demonstration
my interest in the Breeze.

I haven't heard of Captain Mobility before. will have to look it up.

Trekker Breeze is strictly auditory but can't hook up to a Packmate as
you know. IT does give you which streets are in what direction and
more details if you set a route, and will redirect you if you go
off-route. IT's rather accurate and landmarks are excellent as far a
location goes while passing a particular place.

Unfortunately, it seems that everyone has the standard $700 or so when
it comes to the latest GPS. I had to save a llong time to get mine. Do
you have a Lion's Club where you can inquire about a grant? If you
give a good cause to why you need the device, they most often would be
happy to assist in the funds to get it for you. IT may take some
time--sometimes months before you hear back from them--but I have been
successful in obtaining a few adaptive pieces of tech from them. I
understand about thethe finantial cost. Very high for such rather
essential equipment for most of us.

Actually I was looking for a stand-alone gps that is accessible. As an
example, a Garmin. I'm not necessarily lookng for a Garmin, more or

gps where I don't have an extra unit, such as a Braille Note(which I
have), or a PacMate(which I do have). I know Freedom Scientific has the
Street Talk, and I have seen the Trecker Breeze. Not only am I looking
a a one unit gps, but something that is more auditory. I read Braille,
do more auditorily. I'm loking in to the Captain Mobility gps. Has
ever heard about that or know anyone who has had one of those? It seems
that no matter what I do, for an accessible gps, I'm going to spend
of $600. I can't afford that just now. I just started a part-time job
it's not even enough to pay the bills. I have other sources which help
that manner.

I had a question from a gentlemen when I was enquiring about the usb tv
tuners. The gentlemen said he had the Hauppauge usb tv tuenr. I am
as to what model you have. All of your feedback has been helpful thus
