Gps timing antenna

The Global Positioning System GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites that continuously orbit the earth.

Coded signals are broadcast by each of the satellites with the exact time and position of the satellite. All GPS receivers use an antenna to receive these signals. Practically speaking the antenna must have a clear view of the sky and thus be mounted on a roof, or in some cases in a window. The antennas are relatively small, coffee cup size or smaller, and are connected to the GPS receiver typically via coaxial cable.

Since the GPS signal is very weak the antenna usually amplifies the signal to drive it through the cable to the receiver. Antenna cable however offers some resistance and the GPS signal strength will attenuate as it travels down the cable.

GPS receiver sensitivity is finite so if the cable length is too long the signal will be too weak for the receiver to detect it.

Consequently it is very important to know the distance in advance between the antenna and the receiver so that the proper cable solution can be installed. The roof mounted antenna is required for the more accurate GPS clocks since at least three satellites are required to be in view at all times to maintain timing accuracy, typically nanoseconds to UTC. The window mounted antenna is applicable for the network time servers which operate with a lesser degree of accuracy, typically microseconds or in some cases low milliseconds to UTC, and can function with as few as one intermittent satellite in view.

The roof mounted antenna is always preferable since by nature of its location has the best view of the sky. This is a special GPS antenna that receives the GPS signal and down converts it to a lower frequency that is then sent down the cable. Next to the GPS receiver is an up converter that converts the signal back to the original frequency and delivers it to the GPS receiver.

This process is transparent to the GPS receiver. When selecting a site for the roof antenna, find an outdoor location that provides full degree visibility of the horizon. In most cases, this means locating the antenna as high as possible, such as on the roof. Any obstructions may degrade unit performance by blocking the satellite signals. Blocked signals can increase the time for satellite acquisition, or prevent acquisition altogether.

A short mounting mast and hose clamps are provided with the roof antenna to mount the antenna to a pole or the peak of a building. The antenna mounting mast and clamps are well suited to attach the antenna to a vent pipe or mast affixed to the roof.

The pipe must be rigid and able to withstand high winds without flexing. MultiPath interference is caused by reflected signals that arrive at the antenna out of phase with the direct signal. This interference is most pronounced at low elevation angles from 10 to 20 degrees above the horizon. The antenna should also be at least three to six feet m from a reflecting surface. The window mount antenna is suitable for use only with the network time server products with appropriate versions of firmware.

For window mounted antenna installations it is best to use a window with the best view of the sky.Decide which cookies you want to allow. You can change these settings at any time. However, this can result in some functions no longer being available. The low noise, high gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs.

Their unique radome shape sheds water and ice, while eliminating problems associated with bird perching. PCTEL offers an array of compatible mounting configurations. Custom models or site kits options are also available. The antenna features transient voltage suppression as well as protection from reverse polarity and electrostatic discharge ESD.

Product Datasheet.The timing reference antennas are specifically designed for long-lasting, trouble-free deployments in congested cell-site applications as well as broadband and WiMAX networks. The proprietary quadrifiliar helix design, coupled with multi-stage filtering provides superior out-of-band rejection and lower elevation pattern performance than traditional patch antennas.

How GPS Receivers Work

Antenna incorporates a 40 dB low noise amplifier gain. Hardware not included. Only logged in customers who have purchased this product may leave a review. This passive device connects antenna amplifier power through one of the output ports to the antenna using the power provided by the time server. The second port is DC blocked. No changes in setup of the TimeMachines Time Servers are required to use this device.

Compatible with other vendors GPS based time server products, see documentation for more information. Works great with the puck antennas provided with our time servers as well as our conical 40dB outdoor antenna. If there are multiple time servers co-located, this product can save running multiple antenna cables. The splitter function is passive with all ports DC blocked. The included 9V power supply is used to power the antenna amplifier for longer than ft cable runs with low signal loss cable.

TimeMachines is starting to see supply chain impact from the coronavirus. Please note that orders will be held until all items are in stock, unless specified in the order notes that partial shipments are required.

Antenna Product Search Contact.The dominant theme for the wireless evolution is network densification. This GNSS antenna supports the evolution. Given that signals received from GNSS satellites are weak and arriving from any direction, it is clear that choosing the correct antenna for telecom is important.

The GNSS active antenna amplifies the received signal to compensate for potential losses in long coaxial cables. Power is delivered from the front end through the coaxial cable itself.

Characterized by low noise and high gain to provide optimum signal quality, the L1G1A-STD has been tuned for performance and function.

It features a durable, snow mitigating ice radome that protects the antenna from harsh environmental surroundings and lightning protection for the antenna element.
