One of the great things about Google maps is it has its roots in XML. To translate for the non-web developers out there, it basically means Google maps are user hackable. This how-to will show you how to make your own annotated Google map from your own GPS data. Plus, you'll be able to tie in images and video to create an interactive multimedia map. We'll walk you through the steps we took to generate an annotated map of a walk we took recently through our hometown, now that it's actually starting to get warm enough to want to walk about!

What is EGNOS? The European Geostationary Navigation Overlay Service (EGNOS) is the first pan-European satellite navigation system. It augments the US GPS satellite navigation system and makes it suitable for safety critical applications such as flying aircraft or navigating ships through narrow channels.

Garmin Technical Information
This table contains a comparison of the various products in the Garmin handheld GPS line. Instead of building a table entry for each product they have been grouped by family. The older multiplex units are represented by the G-38/G-40/G-45XL and the 12 channel parallel units are represented by the G-12/G-12XL/G48.

GPS precision
Doug's Home | Time | GPS | Photography | Internet | Software/Hardware | News/Finance | Consumer/Leisure | Volunteering | Genealogy Other than Time/frequency uses, I'm mainly interested in the Global Positioning System sub-topic of precision (near centimeter accuracy ). This page is under constant construction, so come back later if you are interested in ongoing details. Caveats: I am NOT a surveyor, and my coordinates should not be used as any legal description!
Homebrew DGPS
I decided that I wanted a cheap low cost DGPS reciever so my solution is to build one. This project is just starting but is brought to you by: Jim Bixby Ready to build schematics Tim Hogard -- Keeper of messy notes & webmaster Larry Burg of Purple Computing. and the first sharehardware project. More to come.... The early ideas involved using a FGPA or the Skiper Chip by Pacific Crest but that seems oever complicated and the Skiper Chip hasn't been seen.
Using a GPS watch, XML, and satellite photos
This week's installment of "pt's how-to Friday" is a bit off the beaten path ? literally ?but surprisingly enough, I've received a lot of emails about a project on my running for geeks web site , so I thought I'd show how I make high resolution maps of the places you jog, with the tracks overlaid on top. This is all possible using a GPS-enabled watch, called the Forerunner 201 from Garmin, the included software (Logbook) and a free application called USAPhotoMaps. A little background, I was traveling a lot in Asia and during the holidays and as opposed to going to the bar each night, I thought I'd take up running again, so I went to the, the gym ?GPS Tutorial by Trimble Navigation Ltd.

Dana National CORS - The National Geodetic Survey (NGS), an office of NOAA's National Ocean Service, coordinates a network of continuously operating reference stations (CORS) that provide Global Positioning System (GPS) carrier phase and code range measurements in support of 3-dimensional positioning activities throughout the United States and its territories.

GPS faq
This document was found on Peter Bennett's Archive site and edited slightly by Tim Hogard. This was sent to Peter as a recomendation of changes. Peter keeps his version of this at: ftp://sundae.triumf.ca/pub/peter/gpsfaq.txt Most of this is from: Saturday, June 15, 1996 3:07:54 PM Local time So find something newer!Low Cost DGPS
The aim of this project is to produce a hardware and software solution to allow: Real time DGPS by transmitting error data via TCP/IP and other means. Post processed DGPS (ideal for surveying application). The target budget for all the hardware (both the reference and roving station) is 600IRP. Software will be made available under GPL, LGPL or some similar open source licence.This page is available in a framed version . For convenience a Full Table of Contents is provided. NEW!
