GPS outages on West Coast USA

Mysterious? The U.S. government has had the ability to insert an error code into the Ephemeral data since it's creation. In fact, up until Clinton had them discontinue Selective Availability in May 2000, GPS was accurate at the discretion of the government.

Then in 2007, it was put out that the new GPS satellites (GPS III) would not have Selective Availability available at all.

excerpt from link: 'Doing this will make the policy decision of 2000 permanent and eliminate a source of uncertainty in GPS performance that had been of concern to civil GPS users worldwide.'

However, the ability to jam GPS is still needed from a military perspective. So it would make perfect sense to develop the ability.

What I found interesting is that the article you posted is a good gateway to conspiracy theory's about NAWS China Lake. lol. I find it particularly amusing since my last duty station was NAWS China Lake and still have a seasonal home located nearby.

Since I am still there, I have turned on my GPS and see no troubles. Of course, I never really use my GPS anyways.

In fact, I think I'll go on base today and do my monthly commissary trip.

Let's block ads! (Why?)
