For the factors of increased of tasks
enhancements of functions and improvement of integrity and complexity in aerospace camera
application system has raised high and long-term in-orbit autonomy and reliability requirements on camera controller. Based on an actual project application background
this paper has put forward a design method of new high reliability aerospace camera controller in-orbit software reinjection instruction sequence which use TSC695F as kernel CPU and process flow of bootstrap receive
cache
checkout and storage update data. Finally
combined with specific test module for camera controller software re-injection
the validity of the software re-injection method raised here has been verified. Still here gives out reference codes of update data package which generated by the ground. 2012 IEEE.

TDI-CCD can improve the sensitivity of space camera without any degradation of spatial resolution which is widely used in aerospace imaging devices. The article describes the basic working principle and application characteristics of TDI-CCD devices
analyses the composition of TDI-CCD imaging noise
and propose a new method to analyze TDI-CCD imaging noise with statistical probability distribution. In order to estimate the distribution of gray values affect by noise we introduced the concept of skewness and kurtosis. We design an experiment using constant illumination light source
take image with TDI-CCD working at different stage such as stage 16
stage 32
stage 48
stage 64 and stage 96
analyse the characteristics of image noise with the method we proposed
experimental results show that the gray values approximately meet normal distribution in large sample cases. 2011 SPIE.

Anti-radiation TSC695F is usually used as aerospace payload controller in tasks to ensure the aerospace payload having extremely high reliability in abominable space environment. The processor bases on SP ARC V7 architecture with parity check and EDAC
so it could design out high reliable bootstrap loader to guarantee the operation system of VxWorks and application codes loaded correctly and worked stable and high effective. First
this paper put forward the system hardware composition and boot mode which apply for aerospace payload
then it makes clear the related contents of register group initialization
stack initialization
system hardware initialization in bootstrap loader of TSC695F and give out the method to establish TRAP table. That's all through comparing different type of organize mode of program image. After that
compiling of target codes have been described and the kernel code of MakeFile had been given at the same time for reference aimed at the realization of engineering. Although this paper is based on TSC695F
but it could be extended to other embedded system based on SP ARC for bootstrap loader analysis and design
for example
the TSC697 which based on SP ARC V8 with higher performance
so this paper has extremely high engineering value. 2010 IEEE.
