February 2009 Overview I have been dreaming of building a flight computer that will not only control the flight sequence, but also log data aboard a model rocket. But I do need to walk before I can run, so I started with a simple GPS data logger (GPSDL) that is just a piece of my future flight computer idea.
Epson Infineon XPOSYS, World's Smallest GPS Chip Reviewed by Albert on Feb 13 Rating: Epson announced their Infineon XPOSYS assisted GPS chip, the smallest of its kind, measuring at a tiny 2.8 x 2.9 millimeters. Not only that, it uses 50% less energy compared to today’s tech and is more sensitive to signals, allowing even indoor reception.
Google Maps has become the standard mapping utility for everything from getting directions and finding nearby food options to viewing the surface of the moon. Are you getting the most out of your Google Maps experience? Keep reading to get some helpful hints on how to maximize (or minimize) all your mapping desires. The Basics Be specific.
Global Positioning Systems are outstanding devices that have thousands of applications (especially for hacking). We’ve found the web’s best GPS tutorials and projects and gathered them all up just for you. GPS Projects, Resources, and Tutorials: Bluetooth enable your GPS Device Use your GPS for GeoCaching (aka: Like treasure hunting). Everything you’ll ever need to know about GPS. Tons of info and projects .
Google Earth puts an entire planet's worth of useful, relevant, and just plain weird content at your fingertips. As you saw in " The Strangest Sights in Google Earth ," some things in this world are simply out of this world. To find such wonderful sights, you can call on a large library of Earth add-ons. As authors of the Web site Google Sightseeing , we see a lot of these add-ons and collections.
I started this project without really having any idea where it would end up. I started off by deciding it could be interesting to build a device that would sample a 3-axis magnetometer and a 3-axis accelerometer and send that data to my computer via USB. Devices very much like that are often sold as a 'tilt compensated compass', and go for $250-500. I made mine for about $150. I happen to live in the same town as my new favorite hobby electronics site, SparkFun , so I ordered the accelerometer and magnetometer from them, and I was able to pick them up in person a couple days later.
Here are some third party tools that enable you to automatically assign locations to your photos in Google Earth: KML2KML - Windows only. The Photo Track feature of this application allows you to arrange photos on track according to GeoEXIF or GPS data. Check out this example . gpicsync - This enables you to automatically geocode pictures from your camera and GPS tracks. HoudahGeo - Mac OS only.
Lesson Organization: Google Earth How To's - Learn how to do the basics so you are comfortable teaching with Google Earth Student Controlled - Where the student controls Google Earth. Suitable for labs, mini-labs, home school, etc. Teacher Controlled - Suitable for Lectures, Presentations, whole class discussions, etc.
This page describes the steps I went through in my project to connect a Garmin eTrex Summit GPS device to a Nikon D200 camera body in order to record location information in the EXIF data of images captured using the setup. While this procedure worked fine for me, I do not take any responsibility for you or your equipment should you try this yourself. All images can be found in the "Equipment" photoset on my flickr account, here . A parts list in PDF format can be downloaded here . There are seven steps: Step 1 - The circuit diagram and initial circuit layout Step 2 - Soldering the components and jumpers to the breadboard Step 3 - Constructing the box to house the GPS Step 4 - Second stage of soldering, fixing camera and GPS cables, and fitting remote release socket Step 5 - Making the false floor to support the GPS and protect the circuitry and components Step 6 - Painting/finishing Step 7 - Constructing new Garmin to PC cable and downgrading GPS firmware
There are three main ways you can import imagery into Google Earth: Image overlay - (Add > Image Overlay) This is an image that is draped over the surface of the earth (though it can appear elevated as well). Among other things, this feature is useful for importing image files of maps. The picture to the left is an example of an image overlay.

I have been doing a lot of exploring and surveying in the desert recently, and have been trying to find the right GPS mapping solution. The solution I found incorporated stuff I already had (laptop and GPS) with the help of some excellent, nearly free software. The best part is that it works even better than the $900 in-car GPS solutions as it uses always up-to-date satellite data, and is easily sharable. Basically you run Google Earth and use some great donation-ware to link it in real time to a GPS.
