This article explains how GPS time server accurate timing information system to provide highly accurate timing reference Network Time Systems achieved.

GPS is a navigation system used by the military, but can also be used by the civilian population and does not require subscription. The GPS system is a Global Positioning System extremely well known. Each GPS satellite has on board a high-precision atomic clock, ideal for providing the right time for synchronizing computer network.

GPS Time Server: The GPS system in a constellation of 24 satellites in orbit are added, each with a specific reference atomic clock timing and covers the entire globe. The exact time can be transmitted to each satellite. You may receive the synchronization information of a shipment cost GPS antenna and receiver is relatively low.

GPS time as Coordinated Universal Time (UTC), which is similar to Greenwich Mean Time (GMT) transferred. UTC time is the same worldwide and does not change the time zone or daylight saving time. UTC is in charge of a very accurate atomic time standard of atomic clocks in national standards laboratories. UTC second separate coherent by International Atomic Time (TAI) Institute.

GPS radio transmission: The information that the GPS satellite transmission of very low frequency radio signal. There are two designated frequencies are used, one for civilian use coded L1 and coded using military L2.The civilian L1 frequency is transmitted at 1575MHz. It can happen by easiliy plastic and glass, but is blocked by metal and stone.

GPS Location: The prerequisite for receiving the transmission of the maximum number of satellites is a clear view of the sky. Ideally, an antenna mounted on the roof is the best with a 360-degree view of the sky. Conversely, an antenna on the side of the building with a 180-degree view of the sky as the horizon does not show up too dark.

GPS: GPS antenna is essentially a signal amplifier. The antenna improves the reception of GPS signals for transmission over a cable to a receiver for decoding. A coaxial cable is typically used to signal to transfer information between the GPS antenna and receiver. These antennas are available in different shapes and sizes. The antennas are usually mounted on poles are curved and small antennas such as patch antennas. The screw rod antenna mast for the mounting screw. Given that the patch antenna is a small, flat bottom ideal device for mounting on a windowsill.

GPS Receiver: GPS receiver GPS decrypt the message received by the antenna in a usable format. NMEA protocol is the most common of the GPS receiver used. This protocol is to confirm a number of statements that provide information about a package at the time, date and positioning information. NMEA protocol relates to information display visible satellites and satellite tracking.

GPS time server can use a GPS time. These receptors allow different timing functions on a time reference of high accuracy. Receiver synchronization is also an automated survey and compare the satellite atomic clocks to ensure synchronization. GPS time servers can also be an accurate pulse per second (PPS) output that is a highly accurate reference trigger for the GPS synchronization, the receiver generates offers.

GPS antenna installation: the gain of the antenna and coaxial cable is important for the maximum cable length that can be used by a GPS antenna and receiver. An antenna can be used with a GPS time servers have 35dB gain. RG58 coaxial cable has an attenuation of 0.64dB / m at 1575MHz. Therefore, a cable length of 55m 35/0.64 = be used. Improved quality coax has a much lower value for attentuation longer cable lengths. When measuring amplifiers and converters updown GPS can increase the length of the cable. Lightning arresters are recommended on the GPS, an external antenna to protect expensive equipment from lightning damage network
