Garmin Nuvi GPS Mount

Today, GPS is more commonly known by the vehicle navigation solutions. However, the GPS system to many other useful purposes can be used. For example, many solutions for computer network time synchronization, as the NTP time server, use the atomic clocks aboard the GPS satellites for accurate synchronization. The GPS system can be used as an accurate reference clock for synchronizing time-critical applications on computers and networks. This article describes howComputer systems can use the GPS time and discussed what equipment is needed to represent a precision time reference.

The GPS system is a U.S. military intended for worldwide navigation. GPS is a space system consisting of a network of 24 satellites in orbit. Precise navigation and positioning is accomplished using precision timing signals and triangulation from several satellites. To provide a precise time, eachSatellite has an integrated high-precision clock onboard atomic. Each satellite broadcasts time information within a few nanoseconds to deliver timely positional accuracy of better than 10m. The exact date will the information be for the NTP servers and other computer timing devices as a very precise time reference used. The great thing about GPS is that it works anywhere in the world and is completely free to air service.

Each GPS satellitesends a low-power radio to the surface of the earth. Two separate frequencies are used, called L1 and L2. The L1 band is the civilian signal transmitted at 1575.42 MHz L2 is the military spectrum, designed for high precision positioning. Transmission of radio signals over the air through the line of sight. The transmitted signal is easily powerful enough to penetrate clouds, glass and most plastics, but also absorbs more important material such as brick,Roofing materials and metals. The ideal location for a GPS antenna tends to be outdoors and, ideally, on a rooftop with the best view of the sky.

To get to this point and the GPS position information, some relatively cheap equipment is not necessary. A GPS antenna can be used to improve the GPS receiver and radio signals. While a GPS receiver decodes the information and presents it in a computer readable format. Many antennas are availablewith integrated receiver, but these have the disadvantage of only a few meters of cabling offers the NTP server or host computer system. Robust to install GPS marine antennas screwed onto a threaded rod rigidly in position to bear the worst of the weather. These antennas offer the best solution for static time applications.

The GPS receiver is usually in the NTP server, embedded or encapsulated in a casing. A GPS receiver is a smallElecronic device, GPS signals will be amplified by an antenna receives a coaxial cable. The receiver decodes these signals and provides a computer-readable output is usually through an RS232 or USB interface. Most receiver decodes the information, such as: location, visible satellites, the exact time and a reference pulse the exact time of departure.

Coaxial cables are used to provide a connection between the GPS antenna and receiver. The cable distance can be critical. TheThe antenna, the GPS signal to increase enough to overcome all the losses that used to run cable for cable. Improved quality of antennas generally provide more amplification (gain), and a higher quality coaxial cables can be much lower signal loss per meter cable allows the use of relatively long, extends between the antenna and receiver. For longer cables, amplifiers can be used to encourage more GPS signals, to overcome cable losses. Typically, a GPS –Amp is now online in the coaxial cable and is powered by the receiver. Amplifiers can run several widely used cable for long.

A roof-mounted GPS antenna may be vulnerable to lightning and power surges. It is recommended that surge arresters are used to protect expensive NTP server timing systems from damage. A wave is essentially a barrier that is seated on line in the coaxial cable between the antenna and receiver, which protectsReceiver from any potential harm from voltage spikes.

In conclusion, the GPS system provides precise timing reference for NTP servers and other computer equipment synchronization. It is a reliable, free, can be used anywhere in the world of air. In addition, with the rise of car navigation technology is needed, to obtain the satellite channels that constantly fall included.
