Processing METOP
Hardware: in FPGA:
PLL, locking at incoming data (I and Q input)
Punctured Viterbi decoder
Descrambler
Framer
USB interface
Software: in wsat:
Catch data from decoder via USB interface
Process AVHRR data for immediate drawing
Save all data; start-of-frame always at a multiple of 1024 bytes
Read saved file, view and translate to hpt format
Processing Fengyun 3
Hardware: in FPGA:
PLL, locking at incoming data (I and Q input)
Double Punctured Viterbi decoder for I and Q resp.
Differential decoder
Descrambler
Framer
USB interface
Software: in wsat:
Catch data from decoder via USB interface
Save all data; start-of-frame always at a multiple of 1024 bytes
Show data, also live while recording
Translate to .hpt or .C10 format
