SATCOM modules are indigenous designs based on our SDR chipsets. We provide a both L and S band MSS terminals, broadcast dongles and transceivers. These are low power, small factor modules supporting a slew of sat-com waveforms. These products currently work with ISRO (Indian Space Research Organization) satellites. Based on customer requests, the modules can be reprogrammed to support specific waveforms and satellites
