The Wide Area Augmentation System (WAAS) is a system that adds precision to the commercial GPS. It corrects GPS signals Cheap St. Louis Blues Jerseys , and provides a more exact location. No additional equipment is necessary to use the WAAS.

The Wide Area Augmentation System is a joint project of the FAA (Federal Aviation Administration) and the DOT Department of Transportation. The agencies devised the system to use for airplane landings that require precision, such as landing on the deck of a ship. The equipment is useful for commercial GPS needs as well as for military and commercial aircraft.

History

The initial intention was to have airplanes depend on GPS for all segments of a flight, including the precision approach to landing strips in a specific area of coverage. However, it was determined that the GPS system alone fell short of the requirements established by the FAA for “accuracy Wholesale Jerseys China , integrity, and availability.”

The Wide Area Augmentation System corrects GPS signal mistakes. Errors are brought about by disruptions in the ionosphere, miscalculations in timing, and orbit inaccuracies. The Wide Area Augmentation System meets FAA regulations and provides crucial and reliable data about the well-being of each GPS satellite. The Wide Area Augmentation System supplements GPS and supplies an accuracy that gives an aircraft the precision needed for a safe approach in any type of weather.

How does it Work?

The Wide Area Augmentation System network contains about 25 Wide-area Reference Stations (WRS). These are ground reference bases located all over the U.S. These stations monitor information that flows from the GPS satellites and evaluate small deviations in GPS signals. The data is broadcast to the three Wide-area Master Stations (WMS).

What are the Benefits?

The Wide Area Augmentation System has several advantages Wholesale Hockey Jerseys , including:

. An expansive inland and offshore coverage
. A WAAS-enabled receiver pinpoints a location within three meters
. It is not necessary to buy more receiving instruments or pay user fees to use the WAAS

Are There Disadvantages?

The Wide Area Augmentation System has these limitations:

. While a Wide Area Augmentation System signal reception is perfect for open land and marine applications, forests or mountainous terrain blocks out the horizon, causing poor reception
. The Wide Area Augmentation System currently only covers the United States, but the plan is to extend the system to other nations.
. An airplane making a Wide Area Augmentation System approach must have an official GPS receiver.

The Wide Area Augmentation System is capable of providing aircraft with the precision needed for safe approaches and in-flight navigation in all kinds of weather. The WAAS is rapidly becoming a standard component of the GPS system. New GPS receivers are now WAAS-enabled.

The Wide Area Augmentation System created a revolution in the aviation industry Wholesale NHL Jerseys , but it is not just for aviation. A GPS receiver able to receive the WAAS signal uses the correctional information generated by the Wide Area Augmentation System and provide additional accuracy for a GPS location. The WAAS satellite only covers only North America at this time. However, other governments, such as Asia, Japan Wholesale Jerseys , and Europe are working on their own versions of the Wide Area Augmentation System. Soon, users of the GPS system around the globe will soon be able to access information on their precise location.

Since from ancient times, the tradition of Yoga has always been passed on individually from teacher to student through oral teaching and practical expression to encompass physical as well as mental well being. The particular manner in which the techniques are taught and practiced today depends on the approach passed down in the line of teachers supporting the individual practitioner.

In the whole, Yoga is built on three main structures: exercising Cheap Hockey Jerseys China , breathing, and meditation.
Firstly the exercises of Yoga are considered to put pressure on the glandular systems of the body, thus increasing its efficiency and total health. Moreover, the body is looked upon as the primary instrument that enables us to work and evolve in the world Cheap NHL Hockey Jerseys , and so a Yoga student treats it with great care and respect.

Secondly, its breathing techniques are employed on the concept that breath is the source of life in the body. As for an instance, the Yoga student gently increases breath control to improve the health and function of both body and mind.

Hence, these two systems of exercise and breathing then prepare the body and mind for meditation Cheap Hockey Jerseys , and find you an easy approach to a quiet mind that allows silence and healing from everyday stress. Therefore, Regular daily practice of all three parts of this structure of Yoga produce a clear, bright mind and a strong, capable body. According to the study revealed by medical scientists Cheap NHL Jerseys Online , yoga therapy is one of the successful practice to enhance balance in the nervous as well as endocrine systems which directly influences all the other systems and organs of the body.

Several benefits of yoga are discussed as below:
Physiological benefits: Studies show it can relieve the symptoms of several common and potentially life -hostile illnesses such as arthritis, arteriosclerosis, chronic fatigue, diabetes Cheap New NHL Jerseys , AIDS, asthma and obesity.

Remedy for asthma patients-Studies accomplished at yoga institutions in India has reported impressive success in improving asthma. It has also been proved that asthma attacks can usually be prevented by .
