SIM908 location error

[xload]

Hello, I'm working with sim908 and Arduino, usually it works well and give me the correct location, but sometimes it give me bad locations, they are too far from real location, between 1 and 10 kilometers, to obtain the location I check if SIM908 is 3D fixed with AT+CGPSSTATUS? command and then I get the location with AT+CGPSINF=0, .

I also checked the number of satellites in this bad locations and It's allways up to 4.

¿Somebody can help me?

How long after you turn the module you usually expect to observe the coordinates? Normally the modules usually take 20-30 minutes to get the correct location.
Try to wait and come back here to tell us about the result.
Hope this helps.:wink:

A lot of thanks TiagoRibeiro, I read the location when module tell me that 3D is fixed, I can not wait 20-30 minutes because it's a movile hardware and I want to save battery.

Here you can see an example: https://mapsengine.google.com/map/u/0/edit?mid=z6POzV3Jmq8M.koz7nyPRLiyc

The device was fixed, aproximately, at 41.294252933333, -1.04744075
