Rival suppliers Data Link Solutions (DLS) and Viasat are working together to ensure users of their Link 16 tactical datalink terminals will be able to migrate to the future software-defined Joint Tactical Radio System (JTRS), writes Graham Warwick.
The redesign will allow emerging capabilities such as the wideband networking waveform (WNW) to be programmed into the Multifunctional Information Distribution System low-volume terminal (MIDS LVT) widely used by NATO forces.
"The transition to MIDS JTRS will provide a software-defined radio with the same footprint as the MIDS LVT," says Bruce King, general manger, communications systems for Rockwell Collins' government systems business. "Using the existing real estate will minimise the aircraft integration task."
DLS is a joint venture between Collins and BAE Systems, with the companies collaborating on design of the MIDS JTRS. "We have divided up portions of the radio based on our competencies," he says. Ultimately the companies will compete for sales of the upgraded system.
The MIDS terminal is being redesigned to make room for three "universal transceivers" that can be programmed with any of the JTRS waveforms, such as Have Quick UHF, Sincgars VHF or WNW. "We will end up with a four-channel software-defined radio, with one dedicated to Link 16 and three for advanced waveforms," says King. The 29-month development programme will lead to low-rate initial production of the MIDS JTRS terminal in 2007.
King says Collins is developing most of the 24 JTRS waveforms under the Boeing-led Cluster 1 programme to develop vehicle and aircraft radios for the US Army.
