APRS and GPS networking, operations and theory by Steve Bowen

Todd Harrison, member of the Superstition Amateur Radio Club (SARC), posted this video by Steve Bowen:   APRS and GPS networking, operations and theory This presentation does not cover how to setup and use Automatic Packet Reporting System (APRS) but does get into its origins, limits, functionality and usage.

DEFCON 20: tools for GPS hacking

At DEFCON 20, Fergus Noble and Colin Beighley discussed the basics of GPS operation and how hackers can access and use its data. They have developed and released a new set of tools which they hope will make GPS accessible to hackers and experimenters. These resources include a library, libswiftnav, which contains a complete toolset […]

GSM GPS shield for Arduino

Boris Landoni draws our attention to the GSM GPS shield for Arduino designed by Open Electronics. “The shield is designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. This new version has several new hardware features, that allow maximum customization […]

GSM/GPRS & GPS modem with SIM900/SIM908 module

Boris suggests we look at this GSM/GPRS and GSM modem. A modem GSM & GPRS with SIM900 or SIM908 module. Allows you to create data connections on the GSM network through a standard USB interface. The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for […]

Coobro Geo Kit: open source Arduino/GPS project

Tyler of coobrolabs writes about his latest open source project, The Coobro Geo is an Arduino compatible through-hole GPS kit that allows you to navigate using only LEDs for direction and distance. It is built around the awesome Fastrax UP501 GPS module (MediaTek MM3318 chip). It is completely open source, so all design files and […]

Review: VPN1513 GPS receiver module

The VPN1513 GPS Receiver Module is a newly released combination GPS receiver and Parallax Propeller mini dev board. It uses a SiRF Star III chipset capable of tracking up to 20 satellites. The module supports both “raw” output mode for raw NMEA 0183 strings and the default “smart” mode for specific user-selected data through a […]

Parallax GPS + Arduino

Here’s a good video from Kevin Darrah for those new to GPS basics demonstrating how to interface the Parallax GPS module with the Arduino. Note that while this video is based on the discontinued PMB-248 module, Parallax indicates that their current PMB-688 module is pin compatible (as far as TTL interfacing is concerned) and will […]

Model rocket GPS altimeter using Picaxe 18X

For his USC Rocket Propulsion Lab, Chris Fenton designed this project using a Picaxe 18X microcontroller which accepts a GPS NMEA data stream, pulls out the altitude and logs it to a 24LC512 external EEPROM. Upon recovery the data is then read from the EEPROM. Source code for the Picaxe and hand drawn schematic for […]

STMicroelectronics debuts single-chip positioning device for multiple global navigation systems

STMicroelectronics announces the impending release of Teseo II, a new generation of single-chip stand-alone positioning receivers for Portable Navigation Devices, in-car navigation and telematics applications. These Systems-on-Chips are monolithic devices capable of receiving signals from multiple satellite navigation systems, including GPS, GALILEO, GLONASS and QZSS. Listed features include 3rd generation positioning receiver with 32 tracking […]
