Hawaii Businesses, Technology & Space
#1
Several Punaweb members have recently suggested we start a thread about new and existing Hawaii businesses, others have pointed out how much space based technologies affect us right here on the Big Island. So I thought it might be interesting to combine these two ideas in a single topic.

For instance, the other day I was driving a rental car with a GPS based navigation system built into the dashboard. Now, it's generally not too difficult to find your way around Puna or Hilo town, but I can see it might come in handy if you're driving somewhere new or unusual. You simply give the unit an address, and it will speak and display directions which notify you of upcoming turns all the way to your destination.

This is thanks to a series of geosynchronous low medium earth orbit satellites (see Eric1600's & TomK's excellent description and explanation below), connected to a ground based computer in your car, here on Hawaii Island. Probably helpful for any number of delivery based businesses, for instance, getting your pizza delivered as quickly as possible without the driver searching on mile long rural subdivision roads for an address. Any others?

It also got me to thinking about the future of these technologies and how they could affect us here in the coming years. For instance, there are many automotive companies that already have self parking capabilities, even automatic braking when the car in front of you is a certain distance away. Tesla has self driving cars (almost).

Imagine a trip from Pahoa to Hilo 15 years from now. Autonomous cars doing most of the driving for you, in conjunction with GPS navigation systems and ground based sensors embedded in the roads. We can take down many of the signs that currently blemish our tropical landscape as the computer will handle speed limits, intersections, and road name designations, even stopping and starting.

I imagine an efficient, safe journey through forests, bamboo, and ornamental fronds, leaves, and colorful petals, somewhat akin to a national park or botanical garden. I also recognize, even though this is (to me) clearly the future, it's not a good idea to advocate tearing down all of the signs now. What would that accomplish other than line the pockets of insurance companies? No, we're in a period of transition, and often in periods of transition we use the best of the old technology as we phase in the new.

It's a brave new world out there, and although south Puna may continue to enjoy it's reputation as an anachronistic cluster on the east side of the Big Island (and I'm glad it is), what part of our space based future have you already integrated into your small business, and personal life? What do you intend to use soon?

I think we're extremely fortunate to live in Puna and (sometimes) have a choice of the best of both worlds. Past and future. Old and new. Mauka and makai.

There are a few that come to mind. Tsunami monitoring buoys in the Pacific communicate via satellite so we're aware of approaching tsunamis. Weather satellites are used to monitor current conditions in and surrounding Hawaii beyond the range of radars. The data they generate are used to monitor storms and help provide real-time tracking information. Satellite telephones are also used by several organisations here for use in an emergency when staff are beyond the range of cellular towers. Even the local TV cable companies use satellites to get their shows from the mainland.

Incidentally, just FYI, the GPS satellites aren't in geosynchronous orbit. They orbit at an altitude of roughly 12,000 and 16,000 miles and orbit the planet two times a day.

Thanks Tom,
A couple of questions.
Are GPS signals then handed off from one satellite to another like cell phone calls from one tower to another?
Do GPS satellites circle the earth closer than a geosynchronous orbit in order to provide a stronger signal to automotive and small handheld GPS devices? Or for another reason?

My brother tried to use his GPS to find my house. He wound up miles away.

And google thinks my HA address is in Ainaloa.

Is this just that not all addresses are registered? That is a problem I've had with deliveries in the past.

Lee - I suspect that's more down to the GPS receiver than the actual GPS system itself.

HOTPE - not an expert on GPS, certainly not the decisions that were made about orbits, but having several satellites orbiting the earth in such a way that several are always available to any location helps with redundancy - i.e., if a few satellites fail there will always be others available in a short period of time.

PS. Maybe this helps. I'm sure there's a better site but at least this should help.

The problem is a map error not the actual gps.You can try to get it corrected, I have filed several:

While you sleep for 2-3 hours, because the roads still haven't been improved...

Plan your Hilo runs in the middle of the night night. You'll be efficiently multitasking.

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.
