thanks! ill be reading them now, and i will let you know haw it goes!

well that would be great, but we mostly need to build it our selves, and there is the factor of cost (how much each will cost?) because we are doing our own robotics team thing, the priority is on 'build it our selves" even if all we can get for accuracy is " they are in that direction"

yes, it does plan on having wifi, why? does wifi have some sort of tracking mechanism i am very likely not familiar with? [EDIT] who: me and the people in the robotics team at my school (FIRST robotics, should look into it ;)) why: when we do our monthly fund raising shindig, we want to have a main screen so that people coming in can see where the VIP's are (mostly for show) so that we can say: "we have some really complicated stuff here, not just making simple RC cars with arms" for GPS, we have one in our laptop, and it gets good signal, although this might just be that it uses a good antena

i am in need for a nice, easy way to find people in a small building, but all they should have to wear is a small device that sends a small "im here and i'm person number 13" signal, and using some receivers of some sort using triangulation to find where each locator is from this signal. my target number of users is from about 60 people to track, and to have an accuracy of about 3 is feet, and time resolution of about 15 seconds. anyone here have any good ideas that can help me? is it hopeless and i need GPS receivers on each person that also send data to receivers?
