GNSS teknologi til tidssynkrone systemer

u-blox tilbyder 'concurrent' GNSS teknologi til brug i forbindelse med opbygning af tidssynkrone systemer i telecom systemer (in english).

u-blox, a global leader in wireless and positioning modules and chips, announced that its LEA-M8T concurrent GNSS timing module is now being used by V3Novus, a provider of a high quality electronic components and embedded system designs based in India, in its latest Precision Synchronization System with built-in NTP Server.

Aimed at the telecom, railway and military application space to provide traceable time stamps for data transported over packet networks, the Time Synchronization System also features a precision Rubidium oscillator to supplement the signal received by the u-blox LEA-M8T module. This gives operators greater confidence in the NTP (Network Time Protocol) server’s output under all conditions.


More digital traffic now crosses more carriers’ networks and passes through more manufacturers’ equipment to reach the end-users. As a result, the demand for phase and time synchronization is evolving.

- As networks migrate from traditional TDM technology to packet switched networks, to accommodate higher amounts of data, V3Novus continues to innovate its time synchronization systems, says Andrew Miles, Senior Principal Engineer, Product Center Positioning at u-blox.

- While standards groups introduce updates and propose new metrics to address packet-based synchronization techniques, the latest offering from V3Novus successfully integrates these developments in time, frequency and phase generation, transfer and consumption. 

The telecommunications infrastructure relies on accurate time stamping for many applications, including VoIP switches/gateways, media servers, SNMP, SS7 and IP traffic monitoring systems, as well as IPTV STBs and gateways.

- We chose to partner with u-blox for our latest precise Time Synchronization System because the LEA-M8T module provides the high degree of time accuracy we needed in this application. We have always found u-blox modules to provide the best combination of reliability and affordability, explains Hemanth Kumar HD, Director Business Development, V3Novus.

The LEA-M8T concurrent GNSS module provides market leading acquisition and tracking sensitivity by supporting the GPS/QZSS, BeiDou, GLONASS and Galileo satellite systems. It integrates the same timing integrity measures found in all u-blox timing products, which includes Receiver Autonomous Integrity Monitoring (RAIM) and continuous phase uncertainty estimation.
