A typical GPS antenna may exhibit a gain of 35db. Low quality coax cable for example RG58 features a attenuation of 0. As such, utilising RG58 cable a cable run of 55m can be achieved. Longer distances can be reached with higher quality coax cable, LMR cable, for instance, has the potential to provide an unassisted cable run of up-to m.

Such high quality cable can however be expensive and can significantly increase installation costs. An alternative option is provided in utilising LMR cable which offers an unassisted cable distance of 80m. With the use of GPS amplifiers, which act to boost the GPS signal even further, it is possible to extend the cable length even further.

The GPS receiver in a NTP server continually issues position and timing data, typically transmitting the data both to and from the receiver via a RS serial interface. The National Marine Electronics Association NMEA protocol is defined by a number of sentences, or character strings, which are transmitted at bits per second.

Just want to add that the registry key change worked not only on Windows 10 but also on Windows 7 and even Windows XP. Your email address will not be published. Skip to content Advertisement. Support us Winaero greatly relies on your support.

A NTP time server solution for synchronising the time across computer networks.

A Network GPS time server used to synchronise computer networks. Galleon Digital Clocks. GPS Atomic Clock providing time synchronisation for computer systems.

To ensure that PPS drivers are there in the kernel by following the steps:. Note: In latest kernel versions, it is possible few packages mentioned above are already installed.

If util-linux is unavailable from both locations, please download the same from here util-linux-ng Note : PPS support can be checked even without the specific hardware by using ktimer which is there in the kernel. NMEA reference clock driver directly accesses the serial port. Corresponding to each X, it creates a pseudo-ip Save and Exit Note : The direct serial port driver As soon as the ntp gets synchronized with the pps the jitter in the time starts decreasing and becomes stable after some time.
