Unifying Software & Hardware
Multi channel bit sync and Best source selector


Contact ewip@unistring.com for more details.
Telemetry test ranges provide effective means of receiving data from multiple on board sensors for post flight analysis. The flight data collection without loss of information is very crucial in telemetry. To overcome the platform limitations, redundancy is employed in transmitter and receiver side. The resulting Multi Input and Multi Output (MIMO) configuration need to be effectively used for reliable data reception.In legacy systems operator observes quality of sync indicators from multi channel telemetry receivers and selects one among them manually. Under dynamically varying channel or platform conditions it is difficult to log the data with manual switchovers. Data loss is unavoidable under transitions. The best source selector (BSS) integrated with bit synchronizers can overcome this limitation. By using BSS the reliable data reception can be ensured, without loss of data even under transition conditions among the channels.
The UTSís Multi-channel Bit synchronizer with integrated BSS is state of the art telemetry equipment realized with modern Software Defined Radio (SDR) principles. The product has built in PCM deframmer for frame synchronization and extracting the selected channel data.  This following are key features and specifications of the product.
The product is available in different form factors for using as PCI card solution or Rack mount solution. Contact ewip@unistring.com <mailto:
