Award for the weakest effort to make some general subject appear to have some Hawaii specific connection.
Grade: D-, so Rob will let you pass because you put Hawaii in the subject line.
Where is the "Hawaii businesses"? Enhanced GPS and self-driving cars aren't going to be Hawaii businesses.
BTW, GPS invented and designed by the Department of Defense and ARPA (back then). DoD wanted position accuracy to less than 3 meters. There are two transmitters on each satellite, a DoD one and a civilian one. It was DARPA that got the civilian transmitter put in. It initially had an accuracy of around 10 meters. There is DGPS now to get this 1 meter accuracy it has now.
Russia (Soviet Union then), China and Europe didn't like the US having a monopoly on global positioning, especially a classified channel. Russia is putting up the GLONASS constellation, Europe is putting up the Galileo constellation and China is putting up their Biadou constellaton now. They all have much higher precision accuracy than GPS.
They all have plans to knock out the other's satellites at the first indication of a global war. China is experimenting with taking out satellites. The US knows this will be the first step, so rapid satellite launch is being worked on, reusable first stage to deliver 2nd stage to orbit with launch of a 3rd stage from there. DARPA wants launch capability every 24 hours.
Think about this. A ballistic missile submarine can't use GPS except when it surfaces. It doesn't need GPS to know where it is. Yet, the skipper knows exactly where he is on this planet, to within 50 feet. The crew doesn't even know where they are, yet they can launch within 30 minutes and strike multiple targets over 6,000 miles away with a position accuracy of a couple feet, vaporizing everything within a 30 mile radius, radiation out to hundreds of miles.
And back to Hawaii. Boomers are a big part of Hawaii life and business, not on Hawaii island, but a bit farther to the west.
