A key application for GPS in telecommunications is to provide synchronization in wireless basestations. Base stations depend on timing to operate correctly, particularly for the handoff that occurs when a user moves from one cell to another. In these applications holdover is used in base stations to ensure … See more Two independent clocks, once synchronized, will walk away from one another without limit. To have them display the same time it would be necessary to re-synchronize them at regular intervals. The period between … See more Synchronization is as important as power at the cell site. The quote above suggests that one can think of holdover in synchronization applications as analogous to running on backup power. Modern wireless … See more In applications that require synchronization (such as wireless base stations) GPS Clocks are often used and in this context are often known as a GPSDO (GPS Disciplined Oscillator) or GPS TFS (GPS Time and Frequency Source). NIST defines … See more • Time and Frequency Systems • GPS Disciplined Oscillator Modules with Holdover Compensation • Holdover Oscillators • Disciplined Oscillator Options See more GPS is sensitive to jamming and interference because the signal levels are so low and can easily be swamped by other sources, that can be accidental or deliberate. Also … See more In Synchronization in telecommunications applications holdover is defined by ETSI as: An operating condition of a clock which has lost its controlling input and is using stored data, acquired while in locked operation, to control its output. The stored data are used to … See more • Synchronization • Synchronization in Synchronous optical networking • Time transfer • Timekeeping in Global Positioning System See more WebGPS NTP+PTP Network Time Server (TM2000B) $ 549.99. The TM2000B is the latest release in the TM2000 NTP/PTP GPS time server product line with improved holdover accuracy, but the same price, features, and reliability of the TM2000A.
