Migliorare l'accuratezza o precisione del GPS

[dan83m]

Ciao , come da titolo volevo sapere se è possibile migliorare la precisione del GPS del galaxy s2 , ho notato che agganciando circa dai 6 a 8 satelliti si ha un margine d errore di 10 metri e da 9 ho gia un margine di 5m , c ' è un modo per poter migliorare tale margine? Se si come?

Il segnale gps ha un'accuratezza di + - 10 metri. È una precisione metrica. Esistono delle metodologie per trasformare la precisione da metrica a centimetrica e sono i servizi RTK (puoi andare a curiosare il sito italpos), ma chiaramente non sono servizi dedicati ai possessori di telefoni cellulari.
Qualunque altra "soluzione" che ti verrà offerta o suggerita non può migliorare questo limite di precisione, almeno fino a quando non sarà terminato e reso pubblico il galileo

ma il nostro sgs2 non è predisposto alla ricezione di questo futuro servizio... pertanto... ti devi accontentare così...

Galileo: il 28 settembre partiranno due nuovi satelliti

Oppure ti dai al modding e usi una patch che ti fa lockare 11 satelliti,ma direi che come ha detto MrG va più che bene

AGPS PATCH

REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.

List of officially supported devices is at the bottom of this post.

Use this if you're having GPS issues (unreliability, no functionality, etc.)

This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.

HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)

Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.

Method 2:
1. Download the patch
2. Copy all file(s) into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.

Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.


Downloads:
SEE THE NOTES SECTION (PARTICULARLY NOTES 1,2, & 3) FOR ALL SORTS OF INFORMATION AND FACTS ABOUT THIS PATCH, WHAT EACH BUILD IS FOR, VERSION DIFFERENCES, AND KNOWN ISSUES WITH SOLUTIONS.

Recommended Builds (pick either):

Download the Google Specific v3.1 build here. (Like it? Don't forget to click on "Thanks" and to rate the thread)

Confused with all the options below? As the Notes section dictates: I recommend the GOOGLE BUILD of all devices. Other builds have changes in their SUPL server information and/or other variables pertinent to that manufacturer. These builds do not appear to operate as fast as Google build's but are available for your enjoyment.

Secondo me è meglio se adesso controlli se funziona bene in GPS,io eviterei procedure di cui non sei sicuro

[dan83m]

bhe il gps funziona bene , e solo che avvolte non so perche ma ci mette qualche secondo in piu a beccare il segnale , e non prende sempre 8 satelliti , volevo giusto migliorarlo un po :/

Se hai dubbi fai prima a chiedere nel thread della patch ,li ti sapranno dire di sicuro..
Io la provai ma non usando molto il GPS dopo un full wipe la persi e non mi sono più preoccupato di usarla...

ok provero li !
