This paper presents a parametric optimization approach to solve reentry guidance. Due to the various constraints imposed on the trajectory
original guidance problem can be converted into an optimal control problem with a merit function to be minimized. Direct implementation of method of variation and is too complex to get a reasonable result
while a numerical parametric optimization approach is feasible and efficient if we choose appropriate control variables as the optimization parameters and effective optimization algorithm. A simulation of the approach is performed to show its validity on reentry guidance problem: as the value of merit function converges to acceptable threshold
all constraints are hold. (2013) Trans Tech Publications

When CCD camera photographs massive images in the air
it is very important to compress and save CCD image timely and validly. This paper designs the CCD image compression and mass storage system. The one part is image compression: this paper introduces a reduced memory still image compression algorithm based on Listless Zerotree Coding (LZC). Compared with SPIHT
the approach significantly reduced memory requirement and no reducing the quality of the reconstructed image. The other part is image mass storage: this system uses a kind of special hard disk storage devices that can realize faster data transmission to SCSI (Small Computer System Interface) devices even if it separates oneself from PCs. In the faster data acquisition and storage system
data storage is a key technology. Normal approach is saving the data to mass memories
and then processing and saving the data after complete acquisition. The continuous acquisition time is restricted with the storage capacity in the normal method so that it can't receive the requirement of CCD image storage on many occasions. While its price will be geminate increasing
when we increase the storage capacity. So the approach in this paper is better one to use fast disks on data direct mass storage considering the storage capacity
read/write speed and unit cost. The result of the experiment shows that the system has compressed and saved CCD image validly
so it reached the anticipative purpose.
