Help with Gps

Hi im new with the mod and i want to use the gps command to locate my Turtles. So I put 3 computer with gps host, (using the x y z ) but every time i run gps locate only give meter from the host and "Could not determine position" (I have tried in diferents places and with cpu and turtles)
I have done something wrong or its a bug?

have you placed modems on them as well?

Yes in the host in the turtle and all the others

First thing to check, are all the chunks with the hosts in loaded? basically, if you can't see all 3 hosts, assume they are not loaded and therefore not working. I also recomend adding a fourth GPS transmitter, helps a lot with 3d triangulation as sometimes you can get two possible answers with just 3 if modems are at similar heights.

Thanks it work i was using my hosts in the same height maybe too close to each other i move the host and now its fine.

I have another problem why sometimes the gps locate give me "Ambiguous position" ?

maybe your hosts aren't in exact fit and this prevents the turtle from being sure where it is?

I put more host in very diferent (x y z ) but in the same chunk and its working again thanks for the reply

Yeah, basically, you need to have atleast 3 hosts with different x co-rds, 3 with different y, 3 with different z. All in all, if you use just 3 hosts and make sure none of them share a x, y or z value, it should be alright with just the 3. :(/>/>
