is GPS "Critical Infrastucture?"

 
Quote:

The December meeting of the PNT Advisory Board meeting brought forth important developments and proposals for the protection of GPS as part of the U.S. critical national infrastructure.

The first recommendation was a reiteration of the Advisory Board opinion that the GPS be designated as one of the “critical infrastructures” of the United States. This opinion was based upon the fact that 14 of the existing designated critical infrastructures involves the use of GPS. The feeling was that such a designation would enhance the attention focused upon ensuring GPS reliability.

A Question about Ron Reopsi’s Presentation

In part, he states that: “the use of GLONASS within U.S.-based receivers was not authorized and that, therefore, the frequency band they used was not necessarily subject to protection. In addition, it was indicated that three years ago, procedures were developed whereby one could apply for authorization to the use the GLONASS signals. To date, Ron Reposi indicated that no organization had applied for authorization to use GLONASS, and that therefore it was currently illegal to use it.”

Does this mean that Garmin’s use of the GLONASS satellite system in their Oregon and Montana series handhelds is illegal?

No

There are a couple of things in this portion of the article that were reproduced, and, I think were taken a little out of context. There are no regulations stating it is "illegal" to receive any signal. There are regulations covering almost everything else regarding the use of radio spectrum including regulations regarding the design and construction of receivers. These regulations are highly technical and cover the small amount of radio frequencies used to extract intelligence from other frequencies. Then there are regulations stating what frequencies can be used for what purpose in areas under control of the US Government. The frequencies transmitted by Glonass are assigned to another purpose across this country, but those regulations also have to agree with agreements filed through the International Telecommunications Union. The International agreements specifies they are used for Space to Earth but they require licensing through either the Department of Commerce or the FCC.

Smart phones

My Nexus 4 and 5 devices receive GLONASS signals. The sats are numbered 46 and higher.

I found the article interesting but a bit confusing. Since you are our resident expert in this area, I appreciate the explanation.

Thanks Box Car.

Yes, it is.

Loran 3 is as well. A terrestrial backup is required.
