Best Source Selector



The NetAcquire Advanced Correlating Source Selector (A-CSS™) makes it easier than ever to gather high quality telemetry. In addition to selecting the best signal source from among multiple sources, the NetAcquire A-CSS uses a data fusion engine to time correlate and combine data to eliminate bit errors in real-time. The NetAcquire A-CSS will switch from one source to another source without losing data, unlike other selectors, which can drop critical data when switching between sources.

The ability to correct for time skew between data sources is an important feature of the NetAcquire A-CSS. For example, if one channel provides the data to the A-CSS ahead or behind the same data arriving from another channel, the A-CSS measures the time offset and automatically corrects for the time alignment mismatch. Thus, no data is lost or duplicated when the sources are combined and switched. The A-CSS gives you reliable data every time.


  • Switch from one source to another source while never missing a single frame
  • Time skew correction between data sources
  • Output data that is better than any individual input source
  • Detection of input channel bit errors anywhere in the frame
  • Works on both unencrypted and encrypted data (with specific optimizations for each)
  • Optionally uses signal-to-noise information obtained from Clear Sync Bit Synchronizer
  • Real-time operating system for minimum processing latency
  • Many different operating modes for different environments
  • Support for optionally using advanced data quality information including receiver DQM (Data Quality Metric), CRC or checksum information, and other upstream metrics
  • Summary of real-time data quality with included mission report
  • Interactive display of all source signal data quality metrics, including (if applicable) DQM or signal-to-noise ratio
  • View data from any browser
  • Up to 32 input channels per output
  • Serial input, network input, or a mix of inputs
  • Serial output, network output, or a mix of outputs
  • Reconfigurable COTS-based solution
