Task


 * Background:**The Global Position System (GPS) is a satellite-based navigation system that allows users on land, at sea, or in the air to determine their location anywhere in the world. You may know people who use GPS devices in their cars to find their way around.



﻿﻿Task: Your company's president wants to buy portable GPS devices for all the salespeople who travel by car. The president wants to understand how the GPS system works overall, as well as how the GPS devices function. You have been asked to research and prepare a report that explains how GPS works and the various functions of the GPS devices that are currently available.

Audience: Your audience is the company president, who will make the final decision on which GPS devices to purchase.

Purpose: The purpose of your work is to inform the audience about the GPS system and to compare the capabilities, features, and prices of at least three specific GPS products.

**Procedures:**
 * Consult the Scoring Rubric for the report to help you plan your page.
 * Research the different parts of the GPS system and how they work together to provide information about location, speed, and time.
 * ﻿Next, research the features, capabilities, and costs of at least three GPS devices. The information can be placed in a comparison chart.
 * On your page, prepare a report that explains how GPS works. Include a diagram illustrating how the GPS system uses triangulation to determine location. Also include photographs or illustrations of portable GPS devices.
