The Global Positioning System (GPS) is often hardware, such as NTP Server systems used to provide an accurate time reference for time-critical applications. This article gives an overview of GPS for timing applications and describes the equipment used to install a GPS antenna to a fixed location. Overview – GPS for accurate time The Global Positioning System is a U.S. military global navigation. The system consists of 24 satellites in orbit, each satellite has a highly accurate atomic clock on board to synchronize the UTC. The satellites continuously broadcast position and time information. The time and position information available in the world with a GPS receiver and antenna. GPS works continuously in conditions so all over the world. In addition, there is no setup fee or subscription fees using fixed GPS systems. Many computer timing systems and NTP Server systems use GPS as a precise external timing reference. The precision of GPS timing system GPS receivers provide highly accurate position and timing information. Typically, a GPS receiver providing position information with an accuracy of 15m. NTP server systems may receive timing information from GPS to a resolution of a few nanoseconds. The GPS signal The information transmitted GPS signal is very low, low-power radio signal, called L1 and L2. L1 GPS frequency is transferred to the 1575th Civilian 42 MHz. The signals travel by line of sight and can through clouds, glass and plastics are blocked by objects such as metal and masonry. Therefore, the ideal place for a GPS antenna on the roof with a 360 degrees on the sky. However, often the installation on the side of a building or in a window can provide adequate results. In general, the larger view of the sky, the more likely a good signal to lock online. Types GPS Timing Antenna The GPS antenna acts as an amplifier for amplifying the GPS signal for transmission to a cable, coaxial rule adopted by the GPS receiver. Timing GPS Antenna with NTP server systems use a pole mounting system available. The screws with a threaded rod antenna must be installed on rooftops. This arrangement allows the GPS antenna with a rigid easily able to withstand strong winds without damage. Typically, the GPS antenna is very low, less than 90cm in diameter. Low-cost patch antennas type are also available, but these applications are generally more appropriate vehicles. GPS antenna cables and cabling distances The length of cable that can be used by a GPS antenna depends mainly on strengthening the quality GPS antenna and coaxial cable used in the factory. A typical GPS antenna calendar may have a gain of 35 dB. RG58 coax a relatively low quality as an attenuation of 0. 64 dB / m at 1575 MHz. can run a 55m cable with RG58 cable. work with high quality coaxial cable, as LMR400, a 200m cable can be made simple. However, very high quality coax can be expensive. A good compromise between price / performance is the LMR200 cable, which can be executed without foreign aid to 80m. Develop wiring distance GPS Line Amplifier provide inline amplifier for further amplification of the GPS signal in order to increase the cable distance between the GPS antenna and receiver. GPS-amplifiers are mounted in line with the antenna cable and receive power from the receiver via coaxial cable. No external power is required. Typically, an amplifier GPS Add an additional gain of 20 dB, adding 30 feet of RG58 coaxial low quality coax 40m or 100m LMR200 LMR400 Coaxial quality. In addition, several line amplifiers are used to increase the length of cable to be later. Sharing a single antenna between several receivers – GPS Splitter GPS splitters allow a single GPS antenna by two or more systems of NTP servers are used. The GPS-splitter divides the signal from the GPS antenna in several outputs for synchronizing multiple NTP servers receive. GPS splitter are generally available with 2, 4 or 8 outputs. The protection of GPS – GPS Surge surge suppressors protect expensive equipment NTP server from static discharge such as lightning, which can be sensed by a GPS antenna mounted outside. Surge in online via the coaxial cable between the antenna and receiver, ideally when the cable installed in the building. surge suppressors require a low floor to surge possibly preserved. The climb requires no additional power or wiring.

GPS antennas are an important part of all wireless systems. The GPS antenna works by combining a planar antenna and a frequency converter, which converts the high frequency phase modulated spread spectrum by the GPS system to an intermediate frequency. Today you can find many types and brands of GPS antenna available on the market. You can choose which is best for your own personal or business needs. Can you detail on the Internet about the different models available and choose the one that suits your needs and your budget. Some of the most important reasons to consider including a GPS antenna: 1) For use in car or other vehicle when the GPS device can not or will not be placed near a window 2) For use when hiking or walking in difficult geographical areas, such as the jungle canyons 3) For use in highly developed areas such as downtowns 4) For use in any location where GPS is not a good line of sight towards the sky 5) To minimize the use in a moving vehicle in a temporary loss of signal 6) To improve the best accuracy of the GPS signal with a lock on the number of GPS satellites In fact, here specifically for pilotage services, a number of advantages in the use of the GPS antenna: 1) Reduction of flight time With a GPS antenna, it is possible for a driver to reduce the turnaround time of the plane about five minutes for as low as one minute. 2) improving the efficiency As the air constantly commuted to maintain a constant phase lock with GPS stations, no flight time is wasted waiting for the lost lock on GPS signals. In addition, it also reduces costs by reducing the total flight time of execution. Without doubt, one GPS antenna provides increased efficiency. 3) Minimum investment required Because the technology is based on commercially available components, only a minimal investment is required. A low cost and stable GPS antenna can be added to any existing vehicle or airplane. In general, a GPS antenna many types of situations, regardless of the external environment around the antenna that is designed primarily for stationary applications. The GPS antenna is a high quality solution for adding GPS RF signals marine GPS navigation systems. A particular model of the GPS antenna is the Bullet III, an active antenna with 35 dB preamplifier and a dual filter bandpass. In fact, this mark has been used for many years, as demonstrated by its strength, durability and reliability. But whatever the brand of GPS antenna system, you decide to buy, after all, is that you do what you do at the right price and the expected level of reliability and durability. Get the right fit on your GPS device secure It is important to mount the GPS good to secure your GPS unit so it is less likely to be damaged. In fact, it is quite difficult to find the perfect GPS mount connector on your first purchase of a GPS unit that can hold more from your inventory for this retailer suitable for older GPS devices GPS Mounts. You may need some time and effort of combing the Internet for various auction sites to spend a GPS device to facilitate the mounting. For this reason alone feature, once you buy the GPS device you plan to have decided, you must also purchase the GPS to go along because you could be a distributor, to recommend to your device and its intended use only . Get as much done research on the GPS mounted on the Internet. Many manufacturers of GPS devices may recommend appropriate GPS mounts in their online documentation describes the features and functions. There are a variety of media for different GPS. For those who are not familiar with their GPS devices, some errors in the acquisition process can be made GPS Mounts. Some examples of different media are available: 1) Air rises This mounting allows pilots the option of positioning on the hill or under the yoke according to their needs. Some drivers may even bring their own portable GPS mount and secure a place they prefer. 2) Marine Storage Marine GPS mounts are typically used by navigators to fix their boats, so they use it in a position to the GPS device with ease. Since the units of aviation, most marine units easily removable for safe storage and convenience. 3) Media Notebook There are people who use handheld GPS mounts for vehicles in the fleet. Therefore, the dealer has GPS mount to ensure that the mountain has the same characteristics apply to all vehicles in the park.

Farewell paper mapLong live the GPS! In recent years, navigation systems have made their entry into force in the passenger cars, relegating the big road atlas at the bottom of glove boxes, to make way for a bright color screen interactive. There are three types of GPS:

Embedded systems.
They are fully dedicated to the automobile. There are two kinds: car stereos browsers, no more bulky than a conventional car (size 1-Din) and those equipped with a retractable screen. Very expensive (from 699 Euros), the former can be used in the vehicle where they were raised, but it is more efficient.

Nomads
From the world of boating and hiking, they represent over 90% of sales. Two advantages: reduced cost and the possibility of being transferred from one vehicle to another. The mapping is already pre-loaded on a memory card or a hard disk drive. Although they are often delivered with internal GPS antenna, it is recommended for best reception of GPS signals, buy an optional external antenna if your car has a heat reflective windscreens.

PDA and Smartphone
In recent years become an extension of the mobile office, calendar and address book, PDAs are now offering navigation. An interesting alternative to the nomads, but for safety reasons, must remain off in the car. Because their interface is not intended for automotive use. In addition, their processor is generally less efficient, so the route calculation is much slower.

Never lose your way!
