that's one reason I much prefer android, far more flexible. IOS is fartoo restrictive.

I wonder what makes a receiver different so it works with an IOS
device. I have several bluetooth receivers here, and none of them work
with my iphone, but they work just fine with my android phones.

Les,

More sensitive receivers become important among buildings and

the open, it doesn't much matter what you have.

The acquisition time will be impacted the same way.

Hi Mike,

Thanks for the detailed explanation about GPS receivers.  If one

travels in

an urban area, will the iPhone receiver perform comparably to an

external

receiver?  Also, can you comment on acquisition time of these

receivers

versus the iPhone's built-in receiver?  Thanks.

Les

Great to see all the conversation. Do please change up the subject

line so

we can track the different threads.

We have been testing the Garmin Glo GPS receiver. It is one approved

by

Apple for the iPhone. Because it receives at a rate of 10 times per

second

versus the once per second of other receivers, it won't easily work

with our

notetakers. Chris did get it to work but it wasn't simple.

It will definitely be more sensitive and acquire in more places than

the

built-in iPhone GPS. Remember again that when the iPhone shows a

position,

it can be quite inaccurate if in fact it has no GPS signal and is

just using

the cell signals.

GPS receivers have a sensitivity rating, the lower the DBM, the more
sensitive. The better receivers like the iBlue and QSTARZ have been

in the

minus 150 to 160 range. The Garmin Glo is in the minus 180 range.

It sells for around $99. Here is one more benefit as copied from the

Garmin

website.
GLO can receive position information from both the GPS and GLONASS

satellite

constellations, allowing it to connect to up to 24 more satellites

than

devices that rely on GPS alone. This allows GLO to lock on to

satellites

approximately 20 percent faster and remain connected even at high

speed.

What's more, GLO updates its position information at 10 times per

second -

that's up to 10 times more often than the GPS receivers in many

mobile

devices.
