FIELD: radio engineering; satellite injection-synchronized radio navigation systems. ^ SUBSTANCE: proposed unit that can be used with remotely disposed external standard generator and external power supply at the same time ensuring electromagnetic compatibility of its functional assemblies and has receiver-processor board is provided in addition with three buffer assemblies affording generation of desired reference signal from external synchronizing reference signal for receiver-processor board and its doubling reference signal, as well as unit internal power supply that functions to shape two separate internal supply voltages for buffer assemblies and receiver-processor board from external supply voltage. Receiver-processor board, unit internal power supply, and buffer assemblies are disposed on common bearing printed-circuit board; buffer assemblies are located in shielded areas. Buffer assembly area is shielded over perimeter by means of shielding conductors and on plane, by means of ground sections. Shielding conductors and ground sections are connected through two separate ground conductors to contact labeled BUFFER ASSEMBLY POWER SUPPLY GROUND and power contacts of buffer assemblies disposed inside shielded areas are connected by means of separate three power conductors to contact labeled BUFFER ASSEMBLY POWER SUPPLY. ^ EFFECT: enlarged functional capabilities. ^ 4 cl, 4 dwg |
