This sounds like the newbiest of newby questions but I need advice on how to select a USB GPS dongle.
In my recent post "Preaching to the Choir" I said I was trying to convince my friend to use AR in Europe.
We visited him yesterday and after showing him:
* Dragging route to POIs (for Most Beautiful Villages in France)
* Dragging route to follow coast
* Detailed view of towns and villages (I also showed him how to use offline maps in Google Maps for this. The problem with this is you have to download map before you leave the hotel while you have Internet access. AR is always available.)
* Time of day planning
he says he will give AR a go.
He had already ordered the Dell Inspiron 3000 2-in-1 touch screen PC that I had recommended.
I have bought him a USB GPS dongle previously but he can't find it. He suspects he may have thought it was a faulty USB memory stick and thrown it out!
As far as I am aware:
* AR / S&T will only accept NMEA data at 4800 baud.
Is this correct?
[Aside]
I was wondering whether baud should be capitalised because it is named after Émile Baudot. I misremembered Baudin.
The first letter of its symbol is uppercase (Bd), but when the unit is spelled out, it should be written in lowercase (baud) except when it begins a sentence.

It is understandable that I misremembered Baudin because Nicolas Baudin is a famous French explorer of Australia, especially Western Australia where I come from. The two capes on the bottom left corner of Australia are Capes Naturaliste and Geographe after the names of his two ships.

Another interesting factoid is that there are places in WA named after crew members, eg Hamelin Bay, Cape Peron, Lake Leschenaultia, but, as far as I am aware, there is nothing named after him, though the Baudin's Black Cokatoo is. There is one screeching in the distance as I write this. That's why the name sticks in my mind!

Wrong!
South Australia
Baudin Beach, South Australia, named for the explorer, Nicolas Baudin
Baudin Conservation Park, a protected area in South Australia
Baudin Rocks, an island in South Australia
Baudin Rocks Conservation Park, a protected area in South Australia
Electoral district of Baudin, South Australia, in existence from 1977 to 1993
Nicolas Baudin Island, an island in South Australia
Nicolas Baudin Island Conservation Park, a protected area in South Australia
Hundred of Baudin, a proposed cadastral division on Kangaroo Island
Western Australia
Baudin Island (Kimberley coast), off Western Australia
Baudin Island (Shark Bay), off Western Australia
Not surprising that I hadn't heard of the 2 islands in WA. They are very small and a long way away in the middle of nowhere.

* Fransom GPSGate cannot change the NMEA speed. It can only create virtual COM ports.
Is this correct? Is there any PC software that can reduce NMEA speed to 4800Bd?
This is the cheapest USB GPS dongle on AU eBay.

It is a Ublox 7 that, I believe, outputs at 19,200Bd.
Is this correct?
In the fractured English description it says:
VK-172 automatically adapt the baud rate, the baud rate has any data output
Any idea what this means? Does it mean that if you install the Ublox software you can change the data rate?
If there is no software to reduce NMEA speed and if the Ublox 7 cannot be slowed down what cheap USB GPS 4800Bd dongle is recommended?
