Satellite Time Code Format Generation and Interfacing to Computer With RS-232 Using UART Developed in VHDL
National Remote Sensing Center (NRSC) receives data from different remote satellites like IRS-P6, IRSP5, Cartosat-2, Cartosat-2a, etc., and processes it depending on the user requirements. The satellite data received in X band is in a particular data format. This data has to be frame synchronized using a special hardware. This hardware needs time information in a special format. This time information is added in every line by the frame synchronization hardware. In the proposed project VHDL code has been developed for the generation of time in days, hours, minutes, seconds, milliseconds, microseconds structure in a BCD format. Computer will provide the start time.
