Abstract
Ultrasonic Positioning Systems are used for multiple purposes including underwater positioning. These systems allow precise calculations to be used to allow directivity of submersed devices to be determined. For the 499B project proposed by Dr. Zielinski a design and prototype of a three dimensional positioning system will be done in multiple phases allowing for both testing and refinement. Design and implementation of this project with be done by Jared Vawter, Kevin Clark, and Steven Kalman as part of Limasonic production. Testing will be initiated on land and conversion to a submersed device will only commence once a working prototype has been produced.

1Introduction
1.1Problem Definition
A system is required to monitor the position of an object in three dimensions. The object can beequipped with an acoustic transponder that re-transmits a signal upon interrogation by the basetransmitter. Two-way travel time can be used to estimate the distance between transmitter andtransponder. The phase differences at the three receivers (microphones or hydrophones) locatedat the transmitter site can be used to calculate the direction of the signal arrival. This type ofpositioning is called ultra-short line. This project has several independent subsystems and issuitable for a group of 3 to 4 students.
1.2Team Information
Limasonic will be the group working on the Ultrasonic Positioning System under the guidance of Dr. Adam Zielinski.

1.3Scope of Project
This project will entail the design and prototyping of an acoustic positioning system. The prototyping will involve several steps to establish a proof of concept.
- A single dimension version of the system to measure distance will be designed and prototyped.
- The second dimension will then be tested and prototyped to obtain an angle measurement.
- Integration and testing will then be done to unite both the first two designs.
- Time permitting a functional third dimension will be tested and prototyped allowing an elevation angle to be determined.
2Assigned Tasks
Tasks pertaining to a finished prototype are assigned as followsthough each person will have individual tasks, most tasks will be completed as a group:
Jared Vawter / design of the audio drivers, phase detector design, PIC programming, theoretical calculationsKevin Clark / mechanical design, PIC programming, theoretical calculations, prototyping
Steve Kalman / PIC programming, LCD interfacing, oscillator design, website design, theoretical calculations

4Progress Report
As of writing this document, the following tasks have been completed:
- Design and simulation of a phase detector
- Most parts for Phase 1 have been acquired, including a PIC and a PIC programming board
- Design of the audio amplifiers
- Some prototyping has been done
- Research of existing systems
- Web design initiated
- First Report finalized
5Conclusion
Within the short period give to us to do our first report we were able to do a number of things that will allow a strong foundation in our report and design. This included the acquisition of a PIC, chips, and several tools to begin design and prototyping.
