Continuous TSCM monitoring and geolocation requires precise timing synchronization between the Nodes. In indoor deployments where a GPS signal is generally not available, CRFS’s proprietary SyncLinc™ provides exceptional timing accuracy.

  • Synchronize RFeye Nodes where GPS is unavailable
  • Ideal for continuous TSCM monitoring
  • Cat 5 or optical
  • Snyclinc

High-accuracy synchronization

SyncLinc permits time synchronization of multiple RFeye Nodes. The goal is to allow each node to capture data within one sampling clock cycle of another, by distributing an accurate timing reference from a master sensor to a group of slave sensors.

This highly accurate common-timing reference allows advanced correlative operations, including high-accuracy Power On Arrival (POA) geolocation with indoor Nodes, retaining the full performance of the RFeye Node, even for transient and low-power signals.

The SyncLinc system operates over an internal network independent of the data transfer network. This use of a wired network  allows accurate timing control of the RFeye Nodes in deployments where a GPS signal is not available (for example, inside buildings). Both Ethernet (Cat 5) and optical versions are available to match different deployment restrictions. Distribution modules with 4 and 8 slave ports are available, and distribution modules can be chained.

TECHNICAL SPECIFICATION
