Re: Details about the GPS chip in N810
 

This may be a coincidence. I don't see any difference with my N810.

Re: Details about the GPS chip in N810
 

Could someone please post the size of their /var/lib/gps/nvd_data file?

ls -la /var/lib/gps/nvd_data

It looks like this file contains the GPS almanac. On my device, this file looks truncated -- there is information for only 6 satellites (?)

The size of my file is 23898 bytes.

Thanks!

Re: Details about the GPS chip in N810
 

My file is the same size. It may only contain the last set of active satellites.

Re: Details about the GPS chip in N810
 

Mine is also 23898 bytes. I've tried connecting on different days (i.e. I should be seeing different satellites), and the file always remains the same size, and has the same headings. The data does change though, so there's something going on there (i.e. it's not *just* the customer config data that gspdriver talks about).

Also note that the gps_last_saved_report file is 14000bytes long, which is quite large for a file which need (presumably) only save the lat and long coordinates. Therefore it may be that this file stores the alamnac/ephemeris data.

Another thing to note is that this latter file is mostly filled with 0x00; seems strange to write lots of 0x00 to a file when not writing them would achieve the same end. Perhaps waiting for some kind of upgrade/enable to write useful almanac/ephemeris data?

Re: Details about the GPS chip in N810
 

I am a newbie - just got my 810 this week.

Is it possible for the 810 to offer GPS services over BT to say a laptop or WinCE PDA?

I use Delorme street atlas (not a lot but sometimes) and would like to be able to use this as the GPS. The delorme product is $US 39 and it includes navigation and lots of useful features. Rather than pay $US 139 for a couple year license for the navigation, I would want to use this as a GPS to what I already have. I have asked Delorme if they plan to support this platform but no answer as of yet.

Does this make sense or is my Earthmate GPS far superior to the chip in the 810. I bought the 810 for other reasons and the GPS would be very nice to have....

regards,

Eric

Re: Details about the GPS chip in N810
 

The $50-$70 bluetooth GPS units (51 channel, sub minute acquisition) are all better than the n810. Your earthmate probably is too.

The n810 isn't bad, but it is slow starting, only does 1Hz output (v.s. 5Hz on many newer units), and doesn't include WAAS/EGNOS for higher accuracy. The GPS chip is low power, but the rest of the n810 would be on draining the battery.

So although it is possible (to export the internal GPS via bluetooth, etc.), any existing GPS is likely to be better.

thanks.. I will look into a new unit.

just for kicks how would one go about exporting the GPS to bluetooth. As I said I am new and am just fooling around with the N810 at this point.
