Abstract : A series of tests was conducted on the Helle Engineering, Inc., Model PR-05 Acoustic Ranging and Bearing Measuring System. This system will acoustically measure bearing to a pinger with an accuracy of plus or minus 2 degrees out to a range of 300 yd. The range measuring portion of the system will acoustically measure range to a transponder to a maximum range of 2000 yd with plus or minus accuracy. The transmitted signal of the PR-05 system has a very broad frequency spectrum. This broad spectrum can interfere with other underwater acoustic equipment even when its operating frequency is very different from the operating frequency of the PR-05. (Author)
