What's the longest GPS lock you ever kept?

Just interested here in how long you've kept your device in one area and postition with a GPS lock (standalone). I stood my phone straight up on my desk today and left GPS on with Google Maps. It was acurate for about 15 mins then it started placing me across the field and in of all places, the dirty flood zone down the road! So I was just wondering if anyone else ever has left their GPS alone and discovered it placing you in other areas after a period of time.

About 4 hours continuous. Worked perfectly.

Aww. I meant like keeping in one area. That's a long time though.

I've had standalone on for a couple hours while at work. I didn't check it continuously but I have never noticed it putting me other than where I am. Sounds like you didn't have enough satellites for a few minutes and it went a little crazy. I would guess that being inside caused the problem.

I have let mine sit many times and it never seems to bounce me around. Longest so far i have done this was like 30 mins in a car wash. Never had any issues and it kept me connected with latitude as well

If you are in a building where you get a weak signal or the signal fluctuates, you could lose satellite lock on a few satellites. When that happens, it will bounce you around. Typically you need 3 to 4 or more satellites to get a good fix.

4 Satellites are required for a lock. Three for a position and one for time synchronization. I don't know if the 4th time satellite is listed in programs like gpsviewer.
