As a Rush fan, and having studied their lyrics and read Neil's writing, I have gained some insights into the philosophies they hold. I can only agree with you and not with the people you reference in your last sentence.

Not everyone who enjoys Rush music necessarily understands the messages and concepts in the lyrics.

This idea that the GPS industry "cheaped out on the filters" just won't die, apparently. The fact is, every engineering project is an exercise in trade-offs. Designs must balance the requirements with the budget and laws of physics. When you know the environment, you design towards it. In other words, the GPS makers designed their equipment based on the fact that the nearby spectrum would be low-powered satellite communications. Thus the filters on the front ends of the GPS receivers were built to reject that type of sideband interference. To do otherwise would not not be the correct design decision.

If everyone had to design their RF sections as you imply, every radio receiver in the world would need a 500 dB/decade "brick wall" filter to reject possibly ANY signal not included in its passband. These filters would be so large and complex as to render mobile devices impractical. The costs involved would make such devices too expensive to sell.

Please do not continue to drink the Lightsquared kool-aid. It is toxic.

Aside from a few million pounds (?) of it we have shot into space, all the metal that was here is still here. At some point, when the naturally available materials are simply too costly to mine, someone will figure out a good way to mine the landfills and dig those "gone" materials back up.

A square knot is properly used only as a binding knot. It can collapse and fail when placed under strain. If you want to joint two ropes (or glorious miracle graphene cables) use one of the interlocked overhand bends, such as the Carrick bend, the Zeppelin bend, or the Ashley bend.

I was in Houston a few years ago, and had to drive up north of town to get some equipment. Looked over and next to the highway, I saw DMC's place. Freaked me out a little, 'till I did some research later and found out about the resurrected brand and their manufacturing of cars from NOS and other parts.

...after following a link - Why do I get the page that is several stories behind where I was? The page isn't cacheing properly. Not sure why this is, but it is aggravating to always have to reload the main page just to get back to where I was.

True, Real Time Kinematic DGPS methods with a broadcast or cellular correction signal typically get you below 3 cm absolute horizontal.

On the other hand, fast static observations and post-processing typically yields sub centimeter (usually less than half a cm) results for absolute horizontal positions, even with broadcast ephemeris. You can usually tighten up positions if you wait for precise ephemeris calculations to be published for your time window.

As for any drift, it is taken care of automatically. The ground stations continuously sync the clocks on the space vehicles.
