Radiobeacon receiver ПКИ-Х4
ПКИ-X4 - single board, full-featured, 2-channel radiobeacon receiver for receiving signals correcting station marine differential subsystem DGNSS in the standard RTCM SC-104.
ПКИ - X4 - has two independent parallel receiving channels in the range 283,5-325,0 kHz with manual or automatic mode selection of received frequencies and is intended for use in the satellite navigation receivers for correction of location coordinates in real time with a precision positioning to 1 meter. ПКИ- X4 works at any time of day and year , regardless of weather conditions within the operating zone radiobeacon DGNSS at stopped or in motion.
