Professor Shu Lin's Low Density Parity Check Selected for NASA Mission

Prof. Shu LIn An (8176, 7156) Low Density Parity Check (LDPC) code, devised by Professor Shu Lin and his co-workers, has been selected for use in the NASA Landsat Data Continuation Mission scheduled to launch July 2011 with a design life of 5 years.

The LDPC code development is part of a larger Goddard Space Flight Center (GSFC) effort called the Bandwidth Efficient Channel Coding project and is funded by NASA Headquarter's Space Communications and Navigation (SCaN) program office. For more than 30 years of continuous data gathering, the Landsat series of spacecrafts are one of the most successful series of NASA Earth observing spacecrafts. The high-resolution on-board instruments will produce an aggregate data rate of 384 Mbps with a target bit error rate of 1e-12. More information on Landsat can be found at:
