Hello,
I've new LS970(Sprint) flashed to E975 rom. And I have GPS problem: I can't see any sattelites and NMEA stream, tried several programs. I had same problem with LS970 rom. Should NMEA be active during no GPS signal? Maybe it could be possible to access serial tty where GPS is connected to send it some debug commands? What device in /dev/ is GPS? I don't know if you understand my me
Some time it gets location with accuracy of 20m, but only when connected to wifi internet, but still no sattelites in list.
I am in Europe.
Thank you,
Kęstutis

Hi,
I want a software to send GPS data (NMEA) via Bluetooth (to connect to my laptop and use PC GPS Applications)
Thanks,
No shareware (but at least a 14 days trial )

HI guys, wherre can i down load TOM TOM for X1?
is it "turn by turn" navigation? is that what A-GPS means?
Assisted GPS, generally abbreviated as A-GPS, is a system which can improve the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.[1]

Description
GPS operation uses radio signals from satellites. In very poor signal conditions, for example in a city, these signals may suffer multipath where signals bounce confusingly off buildings, or be weakened by passing through walls or tree cover. When first turned on in these conditions, some non-assisted GPS navigation devices may not be able to work out a position due to the fragmentary signal, rendering them unable to function until a clear signal can be received continuously for up to 40 seconds (the time needed to download the GPS ephemeris).
An Assisted GPS system can address these problems by using data available from a network.
Assistance falls into two categories:
Using information known to the assistance server but not the GPS receiver
It can supply orbital data or almanac for the GPS satellites to the GPS receiver, enabling the GPS receiver to lock to the satellites more rapidly in some cases.
The network can provide precise time.
The device captures a snapshot of the GPS signal, with approximate time, for the server to later process into a position.
Accurate, surveyed coordinates for the cell site towers allow better knowledge of local ionospheric conditions and other conditions affecting the GPS signal than the GPS receiver alone, enabling more precise calculation of position. (See also Wide Area Augmentation System and CellHunter.)
Calculation of position by the server using information from the GPS receiver
The assistance server has a good satellite signal, and plentiful computation power, so it can compare fragmentary signals relayed to it by GPS receivers, with the satellite signal it receives directly, and then inform the GPS receiver or emergency services of the GPS receiver's position.
As an additional benefit, in some A-GPS device implementations, the amount of CPU and programming required for a GPS receiver is reduced by offloading most of the work onto the assistance server. For modern hardware this is not a major consideration but many 20th century GPS navigation devices used Intel 80386-class 16 MHz CPUs[citation needed] or similar hardware.
A typical A-GPS-enabled receiver will use a data connection (Internet or other) to contact the assistance server for A-GPS information. Some A-GPS devices cannot fall back to standard GPS, needing cell tower or internet signal as these A-GPS devices won't function with only GPS satellite signal.
Many mobile phones combine A-GPS and other location services including Wi-Fi Positioning System and cell-site triangulation in a hybrid positioning system.[2]
High Sensitivity GPS is an allied technology that addresses some of these issues in a way that does not require additional infrastructure. However, unlike some forms of A-GPS, high-sensitivity GPS cannot provide a fix instantaneously when the GPS receiver has been off for some time.

You will have to do a lot of reading though..
Hi all
I plan to use the Galaxy Nexus as a music player. I will not activate it with a phone company. Therefore I will not have any voice or data connection. Also, I won't always have a wifi connection.
I would like to know if the GPS will be working under these conditions.
Definition of working : will give me a coordinate of longitude and latitude. Separate programs may require data connection but this is another issue. Might just download offline mays.
Thanks.
Yes, it does work.
Download GPS test from the market.

Above rom is nice, but the GPS does not connect very often. I tried re-flash, re-starts but the problem remains. Strange is that sometimes it connects in 10 seconds, but I can not rely on it.
Who can help me with this.
GPS not connect for everytime in my device. Only searching GPS signal. They found my location only with wifi, not GPS
i have a problem with navigation gps on my huawei rio-l01, the gps antenna doesnt work, it lose signal continously or it is very inaccurate.
i try to reset to factory options in recovery, or different option as: only gps, gps and mobile connection
i think it is an harware problem but I cannot find the spare part on internet
