Prioritized Requirements

written by jesse on September 17th, 2007 @ 05:37 PM

  1. 2d local positioning system (LPS) that returns raw data coordinates
  2. LPS implemented within atrium
  3. LPS coordinates mapped to GPS coordinates
  4. LPS coordinates are within 1 meter of object’s actual positon
  5. Message relay algorithm (enables Xbee chips that are out of range to broadcast message back to control system through other Xbee chips) – OPTIONAL
  6. 3d LPS system that returns raw data coordinates
  7. Algorithm that will eliminate noise and enable accurate tracking in weak signal areas
  8. GUI with map to identify position of tracked object
  9. Intelligent system to determine position in noisy areas without using any assumptions – IF POSSIBLE
  10. Variable position nodes (i.e. localization based on arbitrarily placed nodes) – IF TIME ALLOWS & IF POSSIBLE

    Hello, I'm not sure if this project is still active(Last post was sept 17th, but at least it's this year!) but I would like to say that I am very interested in the concept of determining position with Xbees. I was recently talking with a student at the University of Florida who said he had conducted an experiment and successfully determined position of an object using multiple Xbee's. As far as accuracy he said it was "very good"(Not sure how good that is but hey, sounds good). I would very much like to help this project if it is indeed active. If you guys wouldn't mind someone tagging along please email me! Regards, Harrison Jones P.S. What Xbee's are you guys using? I have been told that only series two will work.

    Hello. We are glad to see that you are taking interest in our research. We have been working on positioning determination using the Xbee's and are having trouble with accuracy of the zigbees in a high noise. We wouldn't mind anyone tagging along sometimes; also, any ideas, articles, documentation, etc. would be very helpful. Where are you located? From now on you can reach me at rysiebe@siue.edu. We will be updating the site very shortly with our initial tests and results. We have links under the documentation page for the Xbee type we are using.

    Hello Harrison, I am glad you have interest in our project. This project is active and will continue through May 2008. Our primary objective is to use the signal strength of XBee chips to determine the position of any object retrofitted with a XBee within our test area (a large open atrium in the Engineering Building of SIUE). If you would like more information about our project, please feel free to check out our reference and documentation section. We will be updating this soon as well as adding a new front page with our project details. Feel free to email me if you have any questions. Also, I believe we are just using the standard XBee module from maxstream.net. I don't think it is the second series though I will try to check up on that and let you know. Like Ryan said, though, you can find more information in our documentation section. Also, check my post in the last article on this page. It may help some of your questions as well. Best Regards, Jesse Cook
