Overview

RFeye SyncLinc is a key component of the RFeye Secure system. It allows multiple RFeye nodes to be phase locked together to allow each node to capture data within one sampling clock cycle of another, by distributing an accurate timing reference from a master node to a group of slave nodes. The SyncLinc system operates over a standard CAT5 cable network that is independent of the data transfer network.

The use of a wired network in this way allows more accurate timing control of the RFeye nodes over and above that of the GPS timing synchronization network (GPS synchronization on the RFeye node is also available). The GPS timing synchronization system can typically achieve 35 nanoseconds RMS between RFeye nodes, whereas the RFeye SyncLinc system can typically better than 25 nanoseconds. SyncLinc is also ideal for situations where GPS synchronization is not possible, practical or desirable, for example with indoor in-place monitoring systems (IPMS) and systems requiring invulnerability to GPS jamming or failure.

The high performance of RFeye SyncLinc allows comparison and correlation of data between individual nodes in a network to within a few nanoseconds, which in turn allows advanced correlative operations including high accuracy power on arrival (POA) geolocation with RFeye Secure, retaining the full performance of the RFeye even for transient and low power signals.
