International sales of the SWR503 radar followed with operational systems installed in Asia (2008) and Europe (2009).[22] In 2007 operation of the Canadian systems was halted due to concerns over the potential for harmful interference with primary spectrum users.[23] In 2010 the unique capability of HFSWR to provide low cost surveillance of the EEZ resulted in a re-evaluation of the technology and subsequent development of a 3rd Generation, (3rd Gen) HFSWR system based on the principle of sense-and-adapt technology that enabled operation on a non-allocated, non-interference basis through the use of Dynamic Spectrum Management . Additional developments included improved range performance, better positional accuracy and reduction of false tracks and earlier track initiation.[24] In June 2019, MAEROSPACE was granted a global license to design,, manufacture, and internationally market the Canadian HFSWR System and its derivatives.[25]
