A Multi-Function GPS Car Computer, Part 1 -  This project was inspired by requests from a number of readers.  Essentially they said that the GPS module was great for obtaining a precise time but could we produce a project that used its full capabilities for use in a vehicle?___ SiliconChip

Autodim Add-On for the 6-Digit GPS Clock -  Here's a low-cost add-on for the Digital GPS Time Display published in the May & June 2009 issues of SILICON CHIP.  It senses the ambient light level, so that a modified program running in the display unit?s PIC controller can adjust the LED brightness to a comfortable levelranging from full brightness when the ambient light level is high down to dim when the ambient light is very low.___ SiliconChip

Build a GPS Boat Computer -  For all the boaties out there, this one could literally be a life saver! You'll never be lost again: as well as telling you exactly where you are at the moment, it will also show you your speed and heading and can even navigate you back to your starting point ? or to that secret fishing spot! It can even tell you how much fuel you're using, along with a host of other vital information.___ SiliconChip

GPS Navigator -  Global positioning system (GPS) is a wonderful technology that has made navigation systems highly accurate and efficient in recent years.  All the mobile phones these days come with an in-built GPS...___ Electronics Projects for You

A GPS Receiver Based Frequency Standard -  Frequency accuracy has been a topic of special interest to many amateurs and experimenters since the early days of radio.  Until recently, the best frequency standard available to most hams was a crystal oscillator carefully adjusted to zero-beat __ Designed by Brooks Shera, W5OJM

A GPS-Synchronised Clock -  Tired of resetting the time on your wall clock? This GPS circuit will convert a standard battery wall clock into a precision timekeeper that never needs to be corrected.  It will even automatically adjust for daylight saving time.___ SiliconChip

Alternative Power Source for Magellan GPS Receivers -  This GPS receiver is powered by 2 AA batteries.  They are only strong enough for the GPS to stay on for about two hours, and this seems like quite a waste.  I would like to be able to use a larger battery, and sometimes even an AC adapter. __ Designed by Ryan Janzen

Application for 1.575 GHz GPS with UPC8211TK -  App Note  Doc #960___ California Eastern Laboratories

GPS & GSM-Based Vehicle Tracking SystE - M -  Presented here is a GPS based vehicle tracking system based on the ATMega16 microcontroller using global positioning system (GPS) and global system for mobile communication (GSM).ContentsAn introduction to GPS based...___ Electronics Projects for You

GPS Driver Module for the 6-Digit Clock, Pt 2 -  Based on the GlobalSat EM-408 GPS module, this compact GPS receiver/driver board mates with the 6-digit display described in Pt.1 to form a self-contained GPS clock.  It can also be housed separately and used to provide NMEA 0183 time and date information to a PC, via a serial port.___ SiliconChip

GPS LCD Display Project -  This is a project that I started back late 2003 when I just starting to learn PIC programming.  I wanted to building something that actually did somthing useful.  This project is based on a PIC16F84.  I actually came up with this idea and then after doing some searching I found that a few people had the same idea.  But, I wanted to build my own that I could call mine, developed by me.  The whole idea is, I have several GPS units with no display __ Designed by Jason KE4NYV from Roanoke, Virginia

GPS Module for Your PC -  Link it to your PC and trace your position on and on-screen map.  There's lots of freeware and shareware to use with it as well.___ SiliconChip

GPS receiver (Gamin, Eagle etc) to PC interface cables -  GPSy (TM) has extensive documentation on how to create your own data cables, and if you are handy with a soldering iron (or know how to use crimp connectors) , there are some instructions.   __ Designed by ©  Global Mapping Systems and Karen Nakamura

GPS Receiver Based Frequency Standard -  Frequency accuracy has been a topic of special interest to many amateurs and experimenters since the early days of radio.  Until recently, the best frequency standard available to most hams was a crystal oscillator carefully adjusted to zero-beat __ Designed by Brooks Shera, W5OJM

GPS Receiver Support Kit -  The GPS interface can be fed in 2 ways: with a stabilized 5V supply or with a 10 to 25V unregulated DC supply.  In both cases the power is fed into the RJ45 connector on point 8.  Pin 7 is DC ground.  The power supply current is first secured with a slow 315mA fuse (in socket).  Then there is a Transzorb device to ground.  This device is a short-circuit for reverse polarity voltages and for voltages above 27V.  It causes the fuse to blow and in doing so, protecting the other electronics and GPS module.

GPS Synchronisation for Clocks with Sweep Hands -  The GPS Synchronised Clock described in the March 2009 issue only worked with crystal clocks that ticked once a second.  The more upmarket clocks have silent sweep hands, which are much more acceptable in a quiet lounge room situation.  Now, with just a few simple modifications, you can upgrade to one of these.___ SiliconChip

GPS-Based Frequency Reference Circuit Mods & Additions -  The short term frequency stability of the GPS-Based Frequency Reference described in the March and April issues can be improved with some circuit changes, as described here.  It's also quite easy to add an RS-232C serial output, so the NMEA data stream from the GPS receiver module can be fed out to a PC for other purposes.___ SiliconChip

GPS-Based Frequency Reference; Part.1 -  Need a source of very accurate 10MHz and 1MHz signals for calibrating frequency counters, radio receivers and signal generators? Here's just what you need: a frequency reference which is linked to the Global Positioning System (GPS) satellites, to take advantage of their highly accurate on-board caesium-beam "atomic clocks".___ SiliconChip

GPS-Based Frequency Reference; PT.2 -  Last month, we published the circuit for our new GPS-Based Frequency Reference and described how it works.  This month, we show you how to build and adjust it.___ SiliconChip

GPS-Synchronised Clock -  Tired of resetting the time on your wall clock? This GPS circuit will convert a standard battery wall clock into a precision timekeeper that never needs to be corrected.  It will even automatically adjust for daylight saving time.___ SiliconChip

Handheld GPS Glareshield (or Dashboard) Mount with Power Supply -  My first two GPSes were both Garmin eTrex models.  One was the original yellow eTrex, and the second was the eTrex Legend which has more memory, and most importantly, mapping capability.  Neither of these is an aviation GPS, but both can be useful in the VFR cockpit __ Designed by Stefan Vorketter

Homemade GPS jammer using a MC145151 frequency synthesizer -  The GPS band pass filter is a 2-pole Toko 4DFA-1575B-12 ceramic dielectric filter from Digi-Key[4], part number TKS2609CT-ND.  This part is optional, but helps clean up the RF spectrum before further amplification.  The filter’s insertion loss is around 2 dB.___ NaviGadget

How to Construct Garmin GPS Receiver Interface Cables -  Application Note __

Improving the GPS-Based Frequency Reference -  Did you build the GPS-based Frequency Reference described in the March-May 2007 issues of SILICON CHIP? Its frequency stability can be significantly improved with a couple of circuit changes, as described here.  The modifications also make it easier to lock the oven crystal to the correct frequency.___ SiliconChip

Low-Power IC Packs GPS Receivers 7/31/01 -  App Note  Doc #953___ California Eastern Laboratories

Mobile APRS / GPS tracking systE - M -  APRS stands for Automatic Position Reporting System and now is taken to refer to a protocol that uses a subset of AX25 packet radio to provide a range of facilities not available to amateur radio before.  The cornerstone of APRS is that the packets are sent using the BEACON text formatand do not require 'connects' to occur first.  This way information can be widely distributed based on both conditions and other stations in the network.  Packets are passed using level-2 digipeating which works most efficiently when full handshaking is not needed. __ Designed by John VK3HJQ

Realtime GPS+GPRS Tracking of Vehicles using Arduino -  Avoid car thef is impossible but now find your stolen car will be easier!   You just need to install your Arduino with the GPRS+GPS Quadband Module (SIM908) in a hidden place in your car, maybe in your trunk, in the glove compartment or under your spare tyre.  Then connect the GPRS-GSM and the GPS antenna and a SIM card, all of this powered with a battery and you are ready! __ Designed by © Libelium Comunicaciones Distribuidas S.L
