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

Monitor Output from Motorola Oncore GPS Engine in Hp Z3801a in GPS Disciplined Oscillator - This project was designed to allow monitoring of the Motorola Oncore VP receiver that is used in the HP Z3801A GPS Disciplined Oscillator. I. __ Designed by Brian Kirby
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
PC-Based GPS Receiver - Today, there are many gadgets available with GPS technology. GPS stands for ‘global positioning system.’ It provides the data corresponding to the position of the GPS receiver itself on international-standard latitude-longitude...___ Electronics Projects for You
Phase Shift Radio Direction Finder - Similar to the system used in modern aviation where an antenna array modulates the phase of an incoming signal. The commercial system is known as Commutated Aerial Direction Finding (CADF) where a ring of 18 identical antennas are each switched on in sequence, just like winding a rotary switch round and round so that one antenna is always connected to the receiver. __ Designed by Harry Lythall-SM0VPO
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
TD-CMP Compass,Tilt/Roll & Temperature Modules - TD-CMP01 (Compass only), TD-CMP02 (Compass and Tilt/Roll) and TD-CMP03 (Compass, Tilt/Roll and Temperature) These are small modules with a Compass, Tilt/Roll (2-axis Acceleration) and Temperature sensors. Interfaces are USB, RS232 and I˛C. Direct LCD readout optional. __ Designed by Michel Bavin
TD-CMP04 Compass v2 - Small electronic compass. Dimensions: 45x36x15mm. Suited for robotics and other various applications. Low current LED indicator (stays lit when heading North) for power saving. Accuracy 1...2° @ 7Hz measurement. Easy calibration. Serial RS232 readout possible. One multifunction push button for power on and calibration. __ Designed by Michel Bavin
