Here is a really good article about how GPS works, and the new satellites going up to replace the aging ones out there now:
It’s really worth reading if you are interested in this world-changing technology.

Updates and features of our real-time GPS fleet tracking system
Apr 15 2010
Today, 4/15/2010, is the “legal” 5th birthday of GPS Insight (as a product we celebrated back in August). I “spun off” GPS Insight from my consulting company as its own legal entity 4/15/2005.
In that time, we have grown from one customer & 286 trucks to having sold over 1,000 customers & over 20,000 tracking devices.
We have gone from 3 employees to over 30, and now have 8 digit revenues and are sustainably profitable (much better than 5 digit revenues and 6 digit losses back 5 years ago…)
My wife was nice enough to remember the “birthday” and send this bouquet of cookies to the office:
Many Heartfelt Thanks to everyone who has helped us make it to this important milestone. It has been challenging for everyone through the past few years with the economy like it is, and we are proud to have helped our customers save money, identify problems, and keep their drivers and businesses safe with GPS Insight’s GPS fleet tracking product.
Here’s to the next 5 years!

Keir is still hiking across the harsh Chilean desert as we speak, tracked with a 5.9 oz. satellite tracker in his pack.
Not to be outdone, I covered 40 miles today in the harsh wilderness myself, with only the assistance of 20 ski lifts, gravity, 2 skis and a couple of beers:
Just kidding, obviously a lot harder to walk 20-some miles across the desert than ski around a bunch. Maybe I should invite Keir next time…

Keir is doing well, in 112th place (out of 127 left in the race), and there are a LOT of people who have dropped out.
The site says he has raced for just shy of 40 hours. We are tracking him every hour with a GPS Insight TT-1900.
I ran a track like this:
And see where he’s gone (roughly — we update once an hour):
This shows 94.2 miles, but it’s been more than that, since he’s not racing in a straight line.
Good luck Keir! He’s got 1 more 25 mile day, then a 50 some mile day tomorrow to complete this race, his second Racing the Planet race.

I’m on a vacation at Park City Utah, and I have a new app for my iPhone called Navionics. It lets you see where all the ski trails are, and search for them, as well as track your own trail.
It’s got great features, but is a shining example of how inaccurate phones are for tracking purposes. The “pins” are GPS Insight, and the little yellow “O”s are my Garmin Edge 705. The red line which goes off the mountain then back at the top of the lift is the iPhone based tracking device. I did not go over the side of the mountain, trust me…
It’s a nice app nonetheless – here are a few screen shots:
But when you take the inaccurate iPhone “track” which NAVIONICS provides out of the map, you can see that GPS Insight (light blue) and the Garmin 705 (red) are both very accurate. The GPS Insight EZ-1000 was set for 1 minute updates, and the Garmin is about 10 seconds between points. The big difference is the EZ-1000 transmits its location every minute, and with the Garmin (meant for bike riding), you need to upload the data when you get back to a PC.
The speeds even match up pretty closely:
Note that this view (from the Garmin website) shows both speed AND elevation (so you can see I went on the long run 4 times, & smaller runs 5 times through the day):
That was enough to kill my newbie snowboarder legs, so I’m taking today off & have plenty of time to write about it…

I have a daily report which comes to me which tells me how close we are to hitting 2 major Alert milestones:
We are very close to sending our MILLIONTH alert out.
Shortly thereafter (unless drivers stop causing alerts which, uh, isn’t very likely…), we will process our BILLIONTH alert check.
We process a huge number of alerts checks and send quite a few each day.
In the short time I’ve been typing this blog article, we have processed 15,282 checks, yielding a relatively small number of alerts — 3.
This is because it’s night and most of our customers’ drivers aren’t driving, let alone speeding, idling, or going in or out of landmarks. Chances are those were odd-hours alerts…
I’ll let everyone know when we hit these marks.
[worth noting, on 8/15/2009, when I last wrote about this, we were only at 350 million checks and 419,000 alerts. Customers are really starting to utilize our alerts more now than they have in the past]

I pretty much have a never-ending supply of EZ-1000′s so I brought one skiing with my 2 boys on a recent trip.
Jack, my older son, is old enough to go skiing (boarding, he would correct me) without me. Actually, he has officially passed me by — he does black runs I refuse to do (small on a board is way better than big on skis when it comes to moguls).
I wanted to know where he was at one point so I ran a quick mobile map on my iPhone & put it in “compass mode” so I could see what direction he was from me.
Here it is (I’m the blue dot, Jack is the red pin):
Here he really was (my eyes are better than the 3 megapixel camera on the iPhone…) — note that he’s between the lift & the ski patrol “house” just like the map shows it:
I ran a 3D history of that device for the 2 days I remembered to bring it and put it in Jack’s pocket & it puts him exactly where my iPhone shows him at 1:44 (note the time in the first screen shot). Waiting 4 minutes at the bottom of the hill for his 2 friends:
Also interesting is the straight lines which depict the lifts very clearly. The main lifts are in the “clutter” of dots on the left side, but the lifts we went on once each are really easy to spot toward the top right.
It’s easy to see which runs got the most use by turning off the “time slider” and looking at just the blue path:
Here are my two boarders:
And by looking at the GPS track as well as how well he was jumping and grinding, I can tell Jack went through the terrain park most of all:
I’ll try embedding a Facebook video I have of him going through the terrain park here:
