Joint Tactical Radio System

The Joint Tactical Radio System ( JTRS, often pronounced jitters English) to be the next generation used by the U.S. military in field operations after 2010 voice and data Funke. Started in 1997 with a "Mission Needs Statement" and a consequent requirement document in 1998 ( it was subsequently revised), JTRS is a software defined radio that will work with the many existing military and civilian radios. It includes built-in encryption and broadband networking software to create mobile ad -hoc networks.

The JTRS program is marked by delays and cost overruns, particularly through "Ground Mobile Radio" (GMR, conducted by Boeing). The problems included a decentralized management structure, changing requirements and unexpected technical difficulties, the increased targeted objectives to size and weight, which in turn made ​​it difficult to complete the required waveforms.

The JTRS is based on the Software Communications Architecture (SCA ), an open architecture that guides designers to operate the hardware and software harmoniously. It regulates the structure and operation of the JTRS so that programmable radios to load waveforms, run applications and can be networked into an integrated system. A so-called core framework provides a standard operating system environment that has to be implemented on any hardware. Interoperability between radios is increased because the same waveform software can be easily ported to all radios.

The Object Management Group (OMG ), a non-profit consortium that produces and maintains computer industry specifications for interoperable enterprise applications and working toward the establishment of an international trade standard, which is based on the SCA.
