jemand das gleiche Problem? oder eine Lösung?
Danke
Ist zwar von der Sygic-Seite, aber trotzdem interessant, welche Faktoren den GPS-Empfang beeinflussen (können):
Our tips for quicker GPS lock:
In order to aquire the GPS signal quickly, please make sure your iPhone has clear view of the sky. If you use our application in the car, please put your iPhone on the dash. Signal will lock quickly and the application will properly display your position when driving.
Please do not move until the iPhone aquires the signal. It takes up to 5 minutes if you do not move. Once the first signal is aquired, you can drive at high speeds with no issues.
It could happen that during the first execution you forbid the access of our application to GPS. You can reset this in your iPhone: Settings -> General -> Reset -> Reset Location Warnings.
The initial location is quicker if you insert a SIM card with access to the Internet over cellular network. The transferred data volume is few bytes only, don't worry. If you are abroad, consider turning Data roaming on when acquiring GPS signal. It is fine to disable it afterwards.
Please make sure your iPhone is either well charged or ideally it is charging. As the battery gets low, iPhone's operating system allocates less energy to GPS, what makes it less responsive.
GPS lock usually takes longer if you restarted your iPhone after you used GPS last time.
Please make sure you don't use PIN lock on your SIM card. If the SIM card is locked, it might be very difficult to obtain GPS lock.
Some of our customers mentioned that Google Maps is quicker with the first GPS lock. That is because Google Maps displays approximate location only as the application does not provide turn-by-turn route guidance. It is not feasible to use this approach in our Mobile Maps application. In order to provide you with good routing our application needs to filter out exact GPS position only. This takes a little longer but it is worth the patience.
