It’s ideal for car, RV and truck drivers, and it offers pricing tiers for each. The CoPilot GPS navigation app is the most expensive on our list, but it does offer a free two-week trial before the annual fee kicks in. RoadWarrior Route Planner for iOS Map app that works offline Get RoadWarrior from Google Play for Android or download RoadWarrior from the Apple App Store for iOS. The app is free and offers in-app upgrades that include unlimited stops, spreadsheet uploading (great for delivery drivers), data reports and account management. Here, either Google Maps or Apple Maps will launch and provide you with turn-by-turn GPS directions. When you’re ready to hit the road, click Navigate to go to your first destination.Here, you will get a route summary that will tell you the fastest route based on distance, total travel time and more. Once all the addresses are entered, click Optimize.Tap the address in the search bar and select Add Stop.It works with Google Maps, Apple Maps, Waze and others. The RoadWarrior Route Planner helps you find the best traffic-free routes by prioritizing your route on time, traffic and schedule. Using the app is relatively easy. Pin 2 is the Rx pin, pin 3 is the Tx pin.Route4Me Route Planner for iOS Find traffic-free routes Will hold the incoming character from the Serial Port. Include the NewSoftSerial library to send serial commands to the cellular module. ![]() The GPS receiver can be purchased from here and costs $ This unit can be purchased from here and costs $60. The interface board can be purchased from here and costs $16. ![]() You have to buy a separate interface board and the GPS unit and connect the two. It outputs positioning and timing date in NMEA 0183 and SiRF binary protocol and has a positioning accuracy of 10 meters without and 5 meters with WAAS. The GPS Module is USGlobalSat EM-406A which is based on the spectacular SiRF Star III chipset. This board can be purchased from here and costs about $100. This module features two UARTS, an SPI interface, and two 10-bit ADC's. The SM5100B is a miniature, quad-band GSM 850/EGSM 900/DCS 1800/PCS 1900 module. The GSM/GPRS Module is based on SpreadTrum's SM5100B. It’s called Arduino Uno and works just as well. This newer version of this board can be purchased from here and costs around $30. I chose the Arduino Duemilanove, which is an open source electronics prototyping board based on the Atmel ATMega328 8 bit micro-controller running at 16 Mhz. The micro-controller is the central controller for the whole unit. The hardware consists of three main components. All the components can be purchased from Sparkfun. The code is licensed under Creative Commons, so you’re free to use the code in this project in whatever applications you wish. There is no software costs involved, since everything is open source. The costs are all associated with the hardware components. Since the positional information is retrieved every second and the maps updated at the same frequency, a real time GPS tracking effect is achieved. It then integrates this information into Google Maps through Google Maps API which displays the position on a map. The javascript would run in the user's browser and has instructions to retrieve the positional information from the mySQL database every second. When a user clicks on the tracking page, Zope, which is an open source web application server, serves up an HTML page with an embedded javascript code. The TCP server stores the incoming positional data in a mySQL database. ![]() The GPS chip outputs the positioning information which is transferred over a GPRS link to the mobile operator’s GGSN (Gateway GPRS Support Node) and then to a remote server over a TCP connection. In a nutshell, this is how the GPS Tracker works. Even if you didn’t have any application in mind, it would be a fun weekend project, you never know, you might find the knowledge gathered during the process useful one day in some form or other. When I started building this, I didn’t have any particular application in mind, but now that I have built it, I can see myself using it different applications, particularly if I can get to lower the cost. I tore down everything and rebuilt it from scratch, making detailed notes and documenting the process. ![]() I began this project mainly to see if I can integrate all the different pieces of hardware and software to make a workable solution, and it took some time, but finally when everything was said and done, it looked pretty cool. This project describes how you can build a mobile real time GPS tracker with integrated Google Maps.
