SamClarke 12:3f164c88df87 2 * This is an SMS based GPS tracker using using the *
SamClarke 12:3f164c88df87 3 * Adafruit Ultimate GPS module and the Seeed studio *
SamClarke 12:3f164c88df87 4 * GPRS arduino shield [SIM900 chipset]. *
SamClarke 12:3f164c88df87 5 * *
SamClarke 12:3f164c88df87 6 * The idea of this project is to leverage the free *
SamClarke 12:3f164c88df87 7 * SMS between Virgin mobile prepaid SIM cards in *
SamClarke 12:3f164c88df87 8 * Australia for long distance communication. *
SamClarke 12:3f164c88df87 9 * *
SamClarke 12:3f164c88df87 10 * NOTE: sendSms() sends the GPS 'extra' data *
SamClarke 12:3f164c88df87 11 * (eg. speed, heading etc) in one message, and your *
SamClarke 12:3f164c88df87 12 * location as a google maps URL in another message. *
SamClarke 12:3f164c88df87 13 * If you are an Iphone user, you can replace the *
SamClarke 12:3f164c88df87 14 * "https" in the URL with "http" and remove the ".au" *
SamClarke 12:3f164c88df87 15 * to get the URL to open in the native maps app. *
SamClarke 12:3f164c88df87 16 * however I have found this to be less accurate by *
SamClarke 12:3f164c88df87 17 * the fact that it doesn't drop a marker on the *
SamClarke 12:3f164c88df87 18 * real locataion, but looks for the nearest address. *
SamClarke 12:3f164c88df87 19 * it seems that the internal GPS is the only object *
SamClarke 12:3f164c88df87 20 * able to be placed unrestricted on the map. *
SamClarke 12:3f164c88df87 21 * *
