Resiliency and security are essential to maintaining a trusted and effective SATCOM environment. A key element to achieve resiliency is the ability of a single satcom modem to support and seamlessly switch between multiple waveforms. iDirect Government (iDirectGov) has developed the WCore, a hardware abstraction tool that transforms any compute appliance into a software defined modem (SDM) creating a unified, flexible platform able to operate multiple waveforms and constellations.
