GPS navigation devices

Case Analysis 3 - Personal Navigation Devices (PNDs) 1Q. Why have Personal Navigation Devices become popular? What technologies are required to facilitate the success of PNDs? ANS: Personal navigation devices can become the next must-have gadgets. They add more comfort in the busy life in the sense that they give you an ability to concentrate on one thing less. PND like, say, GPS are starting to win over customers, from weekend hikers or bikers to people who are just tired of their lousy sense

Navigation Through Sailing “Navigation is the art and science of determining the position of a ship, plane or other vehicle, and guiding it to a specific location.”(Rutledge). GPS is a modern form of navigation, it is used to determine where a sailor is; out this device forever changed the mode used to navigate the high seas, or in my case the high lakes. There are many factors that go into the navigation when it comes to sailing; many factors conclude for when and how a sailboat makes it to the

and infrared (IR) sensors ,real-time assistance via global positioning system(GPS) and an Android device to provide ease of use and portability of the stick due to the popularity of android.The system consists of ultrasonic sensors ,IR sensor, Bluetooth module,Android device with GPS and dual feedback system- auditory as well as vibratory.The aim of the overall system is to provide a low cost and efficient navigation aid for blind. This paper reports on a study that may help visually-impaired people

Positioning System (GPS) is a network of orbiting satellites that send precise details of their position in space back to earth. The technology was invented by the U.S. Department of Defense, Ivan Getting, and Massachusetts Institute of Technology (Gray 4). GPS is well-known for its military applications and was first used by the U.S. to aid in its global intelligence efforts during the Cold War (Gray 7). However, ever since the early 1980s, the GPS has been easily available to anyone with a GPS receiver.

INTRODUCTION The Global Positioning System, commonly referred to as the GPS, is one of the greatest innovations that truly revolutionized the way we function in the 21st century. It’s a space based satellite navigation system that uses 27 satellites and a wide range of networks of powerful computers used to send signals down to earth. These signals carry a time code and geographical data point that allows the user to pinpoint their exact position, speed and time anywhere on the planet. Centuries

our way around without a Global Positioning System (GPS)? How have GPS devices advanced in features to make it more accessible for citizen’s use? In what ways did the GPS impact the communication with other people? In the 1960s, GPS devices were strictly used for military purposes. It was used to find out where the military enemies were and to figure out how far away they were from them for strategic purposes. It also allowed for nighttime navigation, and searches of injured soldiers. By the 1980s,

Abstract— GPS has major issues with security and speed of signal which can be overcome by aiding GPS along with Inertial Measurement Unit using Kalman filter. An inertial measurement unit is based on inertial navigation system which is an autonomous system that provides us information about position, velocity and attitude based on the measurements by inertial sensors and by applying Newton's laws of motion, which determines the vehicle’s current position from knowledge of its previous position and

used maps to help them travel. As we enter the modern age, maps on the internet and global positioning system(GPS) have become a more efficient way to travel because it allows users to get a step by step instruction on how to get to their destination. In 2004, Google debuted Google Maps, a service that that disrupt the GPS device industry and has paved the way for future navigation and GPS related apps. The success of Google Maps was primarily based on the advances of technology, economic events,

geometric calculation including triangulation, trilateration and multilateration, to give user’s relative position to certain RP. When the absolute positions of RP are known, the absolute position of user could be given. • Inertial navigation system (INS): A common navigation method widely used on vehicles like
