JTRS Update

GUIDANCE FOR WAVE PORTABILITY

New Document Provides Lessons
Learned For Waveform Developers.
 

Editor’s Note: This is another in a regular series of updates on the Joint Tactical Radio System (JTRS), as provided by the program’s Joint Program Executive Office (JPEO).

The JTRS Network Enterprise Domain (NED) Program Office has released the JTRS NED Test and Evaluation Waveform Portability Guidelines. This document provides guidance and lessons learned for waveform developers on producing waveform software that can be readily ported to multiple Software Communications Architecture (SCA)-compliant radio platforms.

The document details general development guidelines in addition to specific guidance for general purpose processor, digital signal processor, and field programmable gate array processing elements. JPEO JTRS desired to make this information available to the at-large software defined radio industry; it is also mandatory for all JTRS developers to follow the guidelines. The document may be downloaded at the JPEO JTRS SCA Website, http://sca.jpeojtrs.mil/.

NED develops and delivers portable, interoperable, transformational networking waveforms, such as WNW, SRW and MUOS; legacy waveforms to maintain current force interoperability, for example UHF SATCOM, SINCGARS and EPLRS; and network management and enterprise services software to fully enable JTRS’ mobile, ad hoc networking capability. NED products will produce the networking capability that allows U.S. warfighters at the tactical edge from all military service branches to access and share relevant information in real time. This program is the heart of the interoperable networking capability of JTRS.

As for January 20, 2010, NED product delivery comprised:

  • • Legacy waveforms completed FQT, in JTRS IR (VHF LOS, UHF LOS, HQ II, COBRA, SATCOM 181/182/183/184, SINCGARS, EPLRS, JTRS Bowman, Link-16, HF)
  • • Networking waveforms completed FQT, in JTRS IR (WNW 4.0.1, SRW 1.0.1c); Networking management and waveforms (interim versions) in JTRS IR (JWNM v4.0, SRWNM v1.0R/1.0+, TTNT v6.0). ♦

JTRS is unique among Department of Defense acquisition programs in establishing the programmatic goal of procuring waveform application software in a form that can be ported to different joint tactical radio platforms at a cost considerably lower than that for new development. Waveform portability is a key attribute of the JTRS program because it reduces cost, permits faster technology insertion, guarantees interoperability between radio families, and reduces training and maintenance.
