OVERVIEW The VITA Radio Transport (VRT) protocol is an emerging standard for Software Definable Radio (SDR) applications. It was developed to provide interoperability between a diversity of SDR components by providing a protocol to convey digitized signal data and sensor settings. Its constructs are also utilized to define a framework within an SDR device components.The VRT standard defines a transport data protocol that provides interoperability for many SDR radio applications independent of physical link, application and the internal architecture of the radio. The use of the standard lowers the risk, the schedule, cost and life-cycle-cost of developing new applications. The use of VRT constructs makes it possible to develop architectures that are not locked into a single supplier.
The V49.0 standard defines the framework for VRT, the signal data packets, the context packets, documentation requirements and provides examples in the appendix. The V49.1 standard defines a framing mechanism based on data content, which is useful when the link layer interfaces do not provide framing or when recording data to disk for later retrieval.
A new V49 dot standard to provide control packet definition and exciter packet definition is under development. These packet definitions will mirror the existing status and signal data packet, though, new attributes may be added. Please use the contact information link at the bottom of this page if you are interested in participating in defining this standard or want to kept abreast of our progress.
Status of VRT as an VITA Standard The VRT standards V49.0 and V49.1 passed as VITA standards in November 2007 and January 2008.
Status of VRT as an ANSI Standard VITA 49.0 and 49.1 are proposed American National Standards (ANSI) standards in February 2009.
