INTRODUCTION

SPEEDOMETER
A speedometer is a gauge that measures and displays the instantaneous speed of a land vehicle. Now universally fitted to motor vehicles, they started to be available as options in the 1900s, and as standard equipment from about 1910 onwards.[1] Speedometers for other vehicles have specific names and use other means of sensing speed. For a boat, this is a pit log. For an aircraft, this is an airspeed indicator


GPS SPEEDOMETER-FEATURES

• Speed is accurate +/- 1 mph is shown as speed over ground (SOG) not speed through water
once vessel is moving.
• Course over ground (COG) is accurate to +/- 1 degree once vessel is moving boats and for
high speed performance boats where pitot tubes do not perform well.



EMBEDDED SYSTEM

An embedded system is a special-purpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few predefined tasks, usually with very specific requirements. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded systems are often mass-produced, benefiting from economies of scale.
