Subject: Comments on Management Plan to Determine the Potential Interference Impact to GPS receivers from UWB Transmission Systems, Docket No. 000623194-0221-02
Dear Mr. Jones:
ANRO Engineering, Inc., is pleased to respond to the invitation for comments on the GPS/UWB Measurement test plan as set forth by the NTIA document dated August 8, 2000.
Regarding the Questions for Public Comment, ANRO has the following suggestion in response to Question #2; UWB Transmission System Parameters.
ANRO will deliver to the Air Force in September 2000, a prototype "beyond-the-fence" intrusion detection sensor for military Force Protection applications. This sensor, nicknamed QUPID, for QUick-reaction Perimeter Intrusion Detection, operates with a nominal center frequency of 2.175 GHz, and with a pulse repetition frequency (PRF) of less than 1.5 kHz.
We note that in Table 3: UWB Signal Parameters, that the planned range of PRFs to be tested spans 0.1 to 20 MHz. We respectfully suggest that lower PRF values be included in the test matrix. While adding PRF values will increase the number of permutations to be included in the test, the results may add significantly to the completeness of the test findings.
Please do not hesitate to contact me if you have any questions, or if we can be of further help in this matter.
Sincerely,
Lee R. Cain
President
