Better: USB GPS receiver with the NMEA 0183 GPZDA sentence sent at least once a second. The developer of the Windows software NMEATime2 recommends GPS units with the U-blox 7 receiver, [4] and this software uses a control loop to analyze the text of the GPS timing sentence, and claims to achieve 1 ms accuracy with the technique.
The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. . In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems.
The most common true time source is a GPS or GPS master clock. Time servers are sometimes multi-purpose network servers, dedicated network servers, or dedicated devices. All a dedicated time server does is provide accurate time. An existing network server (e.g. a file server) can become a time server with additional software.
Traccar Server is the main software which include the back-end for device communication and the front-end web interface for managing the GPS tracking devices. [8] [6] [4] The Traccar Manager is a mobile based front end application which can be used to manage GPS tracking devices. [9]
Products included hydrogen masers, rubidium and cesium atomic standards, temperature and oven controlled crystal oscillators, miniature and chip scale atomic clocks, network time servers, network sync management systems, cable timekeeping solutions, telecom synchronization supply units (SSUs), and timing test sets.
More complete synchronization systems, although lacking NTP's data analysis and clock disciplining algorithms, include the Unix daemon timed, which uses an election algorithm to appoint a server for all the clients; [19] and the Digital Time Synchronization Service (DTSS), which uses a hierarchy of servers similar to the NTP stratum model.
In addition to its use in navigation, the Global Positioning System (GPS) can also be used for clock synchronization. The accuracy of GPS time signals is ±10 nanoseconds. [8] Using GPS (or other satellite navigation systems) for synchronization requires a receiver connected to an antenna with unobstructed view of the sky.
