GPS Receiver .................
 

:)Can someone tell me what Bluetooth GPS receiver works well with the N800 running OS2008. I would also like to know the mapping software most users are using? I am thinking of just using Maemo Mapper. Any suggestions will be apprecaited. :confused:

Re: GPS Receiver .................
 

i-blue 737 or 757. Well, pretty much any MTK-based GPS device will do you. But I use and love both i-blues.

Just for the future, fyi, filling your topic title with periods is neither necessary nor appreciated. :)

Re: GPS Receiver .................
 

Hi All... First time, long time.

I'm not an owner yet but hope to be soon. Got burned on Ebay so waiting for resolution. Anyway...in regards to the a GPS unit, will any give vocal directions?

TIA

Take a look at this thread: http://www.internettablettalk.com/fo...ead.php?t=1970

Re: GPS Receiver .................
 

Thanks for the advice and comments on the use of "periods" Will refrain in future

Re: GPS Receiver .................
 

I searched the thread and could not find anything about voice or vocal directions. Thanks anyway.

Re: GPS Receiver .................
 

I use the Holux GPS units (forget the models, but they are small and work well). Install 'flite' for text to speech, and Maemo Mapper will use it and give you verbal instructions as needed... IF you have a route downloaded, and are using it.

I like the Wintec G-Rays 2 (WBT-201). It has good reception. It is a logger, so it keeps logging your track to internal memory even when you turn off/disconnect your N800. Software to configure it and download the tracks is ported to maemo already. It works very well with maemo mapper.

Re: GPS Receiver .................
 

The Global tops, since they do 5hz natively including the HUD model:

the new iTrek coming out does too, and may have a better bluetooth handling (when you disconnect, the GTs turn off after a while except for the HUD model - the iTrek will go to sleep and power up when the BT link is reestablished according to their blurb).

Re: GPS Receiver .................
 

I did a quick search on amazon and found a GPS receiver that is supposed to work just fine and is under 50 bucks. Amazon is a really good place to try for any accesories IMO

Re: GPS Receiver .................
 

5Hz sampling is a waste of time and money on a consumer GPS. You haven't moved far enough in .2 sec to make any difference. Any bluetooth GPS will work fine, AFAIK they all use NMEA protocol and standard bluetooth connections. I have an F-tech with solar cell, which gives somewhat longer run times during daylight. I don't think that's very important, however. It cost about $35 and works fine with everything I've tried it on, including Palm, Windows, and Linux.

The GPS receiver doesn't give you voice directions, mapping, or anything else. Software does that. Standalone units, such as the Garmin Nuvi, have both the hardware and software in one unit, and you don't need anything else with them. They even have mp3 players and bluetooth for phone connections in most models, so you can call the restaurant you're being guided to. You pay for that capability, of course.

My TomTom works

Re: GPS Receiver .................
 

Internal GPS on my N95-3 using Symarctic ExtGPS.

Pros: A-GPS in my phone, which I'm going to carry along anyway,
Cons: GPS and Bluetooth in phone use a lot of battery power, GPS is only an 8 channel unit (but I have no problems with getting a quick lock, unlike some N95 users).

Re: GPS Receiver .................
 

Hi, I can vouch for the i-Blue 737 too. I'm a newbie and was able to get it up and running with Maemo Mapper in no time. Out on the road, the performance is outstanding. Way better than my Holux GPSlim 236 which is pretty much useless in bluetooth mode. Good Luck!

Re: GPS Receiver .................
 

yooper,
Can you please expand on that? I'm considering the GPSlim 236, 240, and M1200. More inclined to buy the 240 or M1200 b/c of size, but I'm wondering what issues you have with the 236 and Bluetooth, since I think they are similar devices.

Re: GPS Receiver .................
 

My GPSlim was easy to connect to the N800. The bluetooth works fine. HOWEVER, I won't recommend the GPSlim 236 because sometimes it is reluctant to connect to the satellites. If you search for "GPSlim 236 intermittent" you'll probably be able to find some complaints.
If I was buying a unit now, I would look for one that logs your route internally. You could use it to track a vehicle, a person (yourself), etc.

Re: GPS Receiver .................
 

Does anyone know if it's possible to use my razr's GPS VIA bluetooth?

Re: GPS Receiver .................
 

I got a GPSlim 240 and it works fine. The only thing that bugs me is that I have to plug it into usb to charge it. I don't always have my laptop with me, so I'd rather plug it into a wall plug.

I don't know what is meant by "pretty much useless in bluetooth mode". Is there some other mode? Anyway, as I say, mine works perfectly most of the time. When I was on a cruise ship off Mexico, there were some times it didn't work, but I was scooting the GPSlim up close to my window and it didn't have that much sky available... Maybe I should have gone outside...

Re: GPS Receiver .................
 

The GPSlim is rather old technology, and won't work as well as newer units which can track more satellites. As for the charging problem, just get a USB charger. You can get them for both 12VDC (cigarette lighter) and 120VDC, for less than $10 each. You just plug it in, put the USB cable into the port, and charge.

Re: GPS Receiver .................
 

I have TT ver 3 and although it will pair with N800 unable to get it to work with MM.
Had old Fortuna Clip on which worked a treat, now trying without much success to get Zycast SG289 data logger to work:(

Re: GPS Receiver .................
 

I like the idea of a logger. But I also like the idea of a 51 channel (The new Freedom 2000) receiver as opposed to the 16 channel.
The sensitivity looks about the same on both. Does the number of channels and the All -in-Sight on the Freedom make a difference in and under dense pine cover?

Thanks

Re: GPS Receiver .................
 

Another vote for GlobalTop MTK based bluetooth GPS receivers. Excellent performance - time to first fix is great, superior performance in the urban jungle. So glad I went that route.

Re: GPS Receiver .................
 

5Hz - You can't go much distance, but you can change angles. This is where I noticed it most, going around a cloverleaf interchange. A 1Hz would update every 60 degrees, the 5hz about every 12. The speed measured is also updated faster or slower (one Globaltop product is a "heads up" display with speedometer, and you really want that going at 5hz).

I also have a datalogging application which makes use of the extra resolution.

But just for position, it is probably not worth it to go at 5hz, but then even .2Hz might be enough.

Re: GPS Receiver .................
 

A 51 channel receiver won't help much. There aren't that many satellites in orbit, much less that many in view at any one time. That's just marketing hype. You're lucky to see even 15 at a time.

Re: GPS Receiver .................
 

Hey I have the Navicore personal Nav kit I got it from amazon for 224. Ive been using it and it is great. Maemo Mapper is nothing compared to the navicore kit. navicore has much more features plus you dont need to download maps it comes with a 2gb mem card with preinstalled maps. BUT for some odd reason I cant use it (including Wayfinder) when I upgraded to os 2008. so I went back to os 2007.

Re: GPS Receiver .................
 

Sorry, I don't know and I bought the WBT-201 last autumn, so didn't have much dense cover yet. Still, I do orienteering runs and the reception also under conifers was pretty good. My naive (i.e. don't have much comparisons) impression is that the sensitivity is very good.

Re: GPS Receiver .................
 

But that's not why it's got 51 channels.. or even 32, or 20. It's for a different reason: Shorter initial lock time. The GPS receiver starts by scanning for satellites, it doesn't know which ones are visible, on which frequencies, or where they are, or maybe even where it is itself (which all makes it difficult to take into account the doppler effect on the frequencies). So it starts out by looking on as many channels as it can, if it doesn't find any it maps its channels to another set of frequencies, and so on. Eventually it'll lock on to a satellite (or a set of satellites, depending), and start downloading initial ephemeris data, and precision ephemeris data.

From then on it goes on with better calculations until it finally knows everything and just listens to those 6-12 satellites it can usually see at the same time.

With a large enough number of channels it can simply look out for all possible satellites and frequencies at the same time, i.e. it'll need only one search cycle. Or fewer cycles, in the case of 20-channel receivers.

The net result is that the more channels, the shorter initial lock time. That's why there's been a transition from 12 channels to 20 channels to 32 channels to 51 channels. There's a big difference between a 12 channel receiver and a 51 channel receiver (I own both types).

Re: GPS Receiver .................
 

Yes, but 51 isn't likely much better than 20 or so. My cheap F-Tech locks on in about 10 seconds, often less. It's not worth paying more money for a couple of seconds quicker, if that. It's still marketing hype, IMO.

Re: GPS Receiver .................
 

51 _is_ better than 20.. it can do the search in one cycle most probably, where with 20 it'll usually take two or three at least. Anyway, when it locks in 10 seconds it is clearly good enough. But it depends a bit on location, and if it's a cold-start situation or not (where again more channels are good). However, 32 channels are probably more than good enough for most purposes - the sensitivity matters more. I paid in any case just $55 for my 51-channel Holux so I'm a happy camper. :D

Re: GPS Receiver .................
 

Thanks to this thread I have a iBlue- 737 on it's way. I don't quite know how to use the whole thing, but I'm sure it will be fun figuring it out.

Re: GPS Receiver .................
 

Very happy with my 32 channel Holux M1000. They're going for under $30 right now on the 'bay.

Re: GPS Receiver .................
 

Also for software - take a look at Roadmap (search the forum) - It's vector based and looks like it has a lot of potential.
/edit - The total space required (in tar.gz format) for all roadmaps for the US is about 2Gb.

Re: GPS Receiver .................
 

Anyone on the n800 who wants to try Roadmap. Please do.

I've just added code in the 'preferences' to set bluetooth address, and it does use libgpsbt to initiate connections. So it should work. I want to support the n800 on os2008. But I don't own an n800 nor a bluetooth GPS. (Got the n810 for Christmas, wanted roadmap on it...)
So if you try it and it doesn't work please post to the forum at- http://garage.maemo.org/projects/roadmap

Thanks,

Re: GPS Receiver .................
 

can someone tell me how to install the I-blue 737 GPS into the Nokia N800? I did it in the past and the settings remained up until I updated to the latest software for the Nokia recently. It does find it and assigns a 4 digit code to it. But I have no way to type that code into the GPS receiver. Can someone assist me on this?

Thank you,

Re: GPS Receiver .................
 

Assign either 1234 or 0000 as the code... one of them should work.

Re: GPS Receiver .................
 

Has anybody bought or used the Global Top G66 Bluetooth GPS unit in conjunction with their N810?

It looks pretty good and the slimmest I could find.

Anybody know of a smaller unit?

Thanks.

Re: GPS Receiver .................
 

Not been here in a while - I ended up getting the global touch G66 - it's freaking awesome. Tiny, slim, connects in seconds, battery is good for 5-8 hours.

By the way...was there ever a fix or update to get the internal GPS to a useable/workable level? If so, please point me in the direction of the thread. Thanks!

Re: GPS Receiver .................
 

so if i get a GPS bluetooth reciever, i can program the n800 to give voice directions with meamo mapper right?

Re: GPS Receiver .................
 

You can, but some of us find them hard to hear because of flite, the voice synthesizer. I've never used a dedicated GPS unit for driving, but I suspect that they're quite superior to Maemo Mapper if that's all you're doing, especially considering how cheap some of them are now. (Saw a good one on digitaldeals.net for $60 recently.) I suggest you check out this thread, especially Posts 19 and 20.
