All recommendations welcome. Main question is whether you have any sort of connection to the internet when you're trying to get a GPS lock? For me GPS on N900 works uber-fast, I mean it's pretty much instant whenever I use it (Google Maps, Map Buddy, OVI etc.). However, I tend to have device always online, so it most likely uses that to download additional GPS data. No, I don't have a connection to the Internet when using Ovi Maps-thats the exact reason why I use Ovi Maps. You shouldn't be expected to use a network connection with an onboard GPS.

Re: N900 and Java
maemo wiki has a page for java, look for it, and u will know whats up with it. But the short answer is not straightforward but there are projects to implement it fully. 2010/2/14 R. A.

RE: Bad experience with N900 onboard GPS.
Based on the documentation of the GPS software, the GPS can run in four different modes, Complementary Wireless Positioning (CWP) - This is based on the location of the country and/or the GSM base station location. It does not use the onboard GPS at all, but depends on the SIM card. Assisted Complementary Wireless Positioning (ACWP) - This is similar to CWP but requires a network connection to get better information about the GSM base station location Global Navigation Satellite System (GNSS) - This uses the GPS receiver. It does not require a network connection or a SIM card. Assisted Global Navigation Satellite System (AGNSS) - This uses the GPS receiver, but gets additional information from a SIM card or Network connection. It works basically the same as GNSS, but since it starts with a good guess at the location is often faster on startup than GNSS. I had a little fun writing some software for the N900 to track a drive I took a while ago. All of the data was extracted using AGNSS and saved to a file which I loaded into Google Maps. You can see the map of my trip, as well as read about the programming I did at #N900 - My New Gps http://www.orient-lodge.com/node/3884 (The link to liblocation in the blog post is where you can also read more information about the various GPS modes) Aldon -Original Message- From: maemo-users-boun...@maemo.org [mailto:maemo-users-boun...@maemo.org]on Behalf Of Dawid Lorenz Sent: Sunday, February 14, 2010 7:43 AM To: Bernard Tyers Cc: maemo-users@maemo.org Subject: Re: Bad experience with N900 onboard GPS.

Using a-gps when roaming is not a good idea, as it costs data roaming charges. Leaving aside the fact it is not proper location positioning.. Causing users more data costs than necessary is a lazy way of providing a feature-the issue here with Ovi Maps and GPS has been identified as a bug. So I am happy. ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

- Original message - Based on the documentation of the GPS software, the GPS can run in four different modes, Interesting, do you know if the gps runs through these 4 modes when starting up ovi maps? Or if you can say what order it goes through? Thanks. Bernard ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users
RE: Bad experience with N900 onboard GPS.
I don't know for sure, but my guess is that it is based on what you have selected in Settings... Location... If you enable GPS and Network Positioning, I would guess you get Assisted Global Navigation Satellite System (AGNSS) If you enable GPS and don't enable Network Positioning, I would guess you get Global Navigation Satellite System (GNSS) If disable GPS and enable Network Positioning, I would guess you get Assisted Complementary Wireless Positioning (ACWP) and if you diable both, I would guess you get Complementary Wireless Positioning (CWP) Aldon - Original message - Based on the documentation of the GPS software, the GPS can run in four different modes, Interesting, do you know if the gps runs through these 4 modes when starting up ovi maps?
