Getting Started with the iBlue 747Pro GPS

This is just a quickie. For the most part, just follow the manufacturer's user manual, which you can find online, on the JLT Map backup DVD, and on the mini-CD that comes with the unit. Because many CD-DVD players have trouble with minidisks and because the mini-CD has only the Japanese manual, I've put the most up-to-date English manual and versions of all the installers onto the JLT Map Back-up DVD (bonus: the back-up DVD also has the Mac USB driver for the GPS, whereas the factory mini-CD only has the Windows version). However, do take a look at the info below, as the manufacturer's manual leaves out a few things, and one thing may not work like the manual says it should.

First, install the software.

Using the 747Pro (basic).

Turn it on. To use for navigation only, turn it on to the "NAV" position. To both navigate and log, turn it on to the "LOG" position. Note that it won't be able to get a fix unless it's outdoors or very nearly so (by a window, etc.). When the yellow light is burning steadily, it's trying to get a fix; once it starts blinking, it's got a fix and you can start using it. If you don't use AGPS, the first time you start it up, it'll keep blinking for 10-15 minutes until it gets a fix; if you do use AGPS, it'll take about 30-40 seconds. Don't try to connect to the GPS in the Mapple program until you've got a fix (otherwise you'll just get a "no signal" error message).

General notes:

The manual on the mini-CD is in Japanese; the English one is included on the JLT DVD and, for easy reference, on the Axim's SD card.

A lot of CD and DVD drives have trouble reading mini-CDs. For that reason, I've included the contents of the mini-CD on the JLT backup DVD. Plus, I've also included the Mac USB driver for the GPS on the backup DVD (the mini-DVD only has the Windows driver). Not only that, but the ones on the JLT DVD were freshly downloaded just before I sent it to you, so they may be more up to date than the ones on the mini-CD.

Some background info on GPS terms you'll see in the 747Pro manual and software.

AGPS stands for "Assisted" GPS--basically, every great once in a while, a GPS receiver needs to download an almanac of information from the GPS satellites; it also needs to do that if it hasn't been used in a couple of weeks or if it's been moved a great distance while off. This can take 10-15 minutes and it's a pain. Once it's done that, then connecting for the first time every day (cold start) takes 30-60 seconds, and subsequent connections take just a few seconds. AGPS downloads the almanac over the net and updates the GPS over the USB cable (the almanac is good for the next six days--though if you're using the GPS every couple of days, you don't need to do it again every six days)--meaning that even if it hasn't been used in a while or has been moved a few hundred km, it'll still get its first fix in 30-40 seconds. So spending a minute at your computer updating the almanac by AGPS saves you from having to wait an annoying long time for a fix when you go outside and want to use your GPS.

"Logging" means that the GPS keeps a record of where it's been while that feature is turned on. You can use that to create routes of hikes, bike rides, etc., to upload to Google Earth, see how fast the shinkansen was going, keep track of exercise statistics (probably requires separate analysis software), etc. But the coolest use is to geotag photos. Put the GPS in logging mode, toss it in your pocket or camera bag, and go take some pictures. Afterwards, after you upload your digital photos to your computer, the PhotoTagger software will attach location data to the meta tags of each photo, and it's also got features to make them show up on Google Earth where they were taken. See the PhotoTagger's documentation for more info--it's pretty simple.

"Push to log" means just that--you push the button on the top/front of the GPS, and it records the place and time you pushed it at. Say you're driving and you want to note a speed camera location, or hiking and want to note a place with a great view.

The logging rate, one of the settings for the 747Pro, means how often it logs a location point, from once to five times a second. Once a second is plenty for most purposes (routes, navigation, photo tagging); five times a second is more for very precise performance analysis (I suppose if you put the thing in the nose of your model racecar or if you're an elite runner or bicyclist). Obviously, at five points a second, you'll use up the 747Pro's memory five times faster. At once a second, the 747Pro's 250,000 point storage capacity will keep track of you for 69 continuous hours.
