I don't see how you're going to get any useful information from an SSID like "linksys", "default", "johns house", etc.. |
Re: What do we know about Diablo (Maemo 4.1) ?
No, there are 2 SSIDs; the MAC address of the AP is also an SSID (BSSID, actually...), and that's what I meant.
Lardman, I haven't used it, and am not all that knowledgeable about GPS in general, so I guess a little less dogmatism (from me) would have been in order. But I think you're confusing AGPS with DGPS/WAAS. AGPS doesn't know a thing about the ionosphere, etc. |

I take back what I said about ionospheric disturbance, perhaps. For this reason: The satellites broadcast Almanac (gross pos'n/speed data) and Ephemeris (fine corrections), the GPS chipset must presumably then use this data to generate a list of frequencies (for the satellites it knows are in view) and frequency offsets (for the Doppler shifts of said satellites knowing their positions and speeds). The SUPL (AGPS) server presumably either provides the AGPS chipset with the raw Alamanac/Ephemeris data from which it does these calculations *or* with the pre-processed data (the former approach would require no processing on the SUPL server, it would simply forward the data it has received from the satellites/DoD; the latter approach would require that it models the location of the satellites and can provide the pos'n/speed for any position on Earth - wherever an AGPS chipset is sat and asking for directions). From what I've read, there are a few different types of AGPS service, and one of these (at least) allows the AGPS chipset to send fragmentary signals back to the SUPL server and it will use brute force to work out the receiver's position (without the receiver needing to capture all of the signals, which contain the Almanac/ephemeris data). So to sum up, I'm not completely clear on what is/can be done either, but for the last case, knowing ionispheric conditions is probably necessary. It's an interesting topic, perhaps we should branch it off into a seperate thread to avoid polluting this one? |

Nitpick: the 1G iPhone. The 2G iPhone (the one with 3G ;) has GPS, doesn't it?

Someone I know is working on an academic research project, sponsored by nokia, which attempts to determine your location from wifi signal strength. Don't know more about it than that.

I wonder how long it took Skyhook Wireless to drive all over the place and build their database, that's crazy :) Hopefully they keep it up to date! |
Diablo Is Out !!!!
i just looked on the maemo site, and maemo 4.1 is out!!! unfortunetlly im a noob and dont know what its improvements are, but go check it out at the maemo site for yourself!!!

How do I install aGPS-ui on my newly updated N810? I googled aGPS-ui and got this:
http://catalogue.tableteer.nokia.com...ser/a/agps-ui/ I tried to install it but: Application packages missing: libglib2.0 (>=2.12.12-losso10) libosso1 (>=2.16) supl-daemon (>=0.27) Where do I get these packages? :[ |

To answer the question "What do we know about Diablo (Maemo 4.1) ?"
I know that using Diablo, it will let me run Microb under other window manager instead of only matchbox. Now you can have microb available under your favorite window manager. This is awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! |
