In order to research the attitude algorithm with angular rate input under the conical motion
a optimal threesample rotation vector algorithm based on single-step Newton backward interpolation is proposed. Using the principle of limited rigid body rotation and the characteristic of angular rate input
three-sample rotation vector algorithm is derivated. To minimum attitude errors
three-sample rotation vector algorithm is optimized. Three angular rate extraction methods of singlestep entire sample recursion
multi-step entire sample and singlestep Newton backward interpolation are proposed. Under the condition of conical motion with semi-cone angle 3 and angular frequency 2rad/s
simulation is done. The simulation results show that single-step Newton backward interpolation is superior to the other two methods
and its maximum error peak is 0.01
error drift rate is 0.036/h. Experiments in three-axis flying turntable with the same parameters are carried out
and the results show that error drift rates of three-channels are less than those of traditional quaternion
which are 13.53%
12.08% and 23.68% lower respectively. It also verified that the new algorithm can perform a high accuracy under the conical motion. 2011 IEEE.

A new design of compound Fresnel-R concentrator is presented which is composed of two lenses: a primary lens (Fresnel lens) that works by total internal reflection at outer facets but refraction at inner facets
and a secondary lens that works by refraction. In contrast to previous Fresnel lens concentrator
this design increases the acceptance angle
improves the irradiance uniformity on the solar cell
and reduces the aspect ratio significantly. Another outstanding advantage of this concentrator is the fact that it mainly works by performing total internal reflection
reducing chromatic dependence as well as Fresnel losses. An optical efficiency more than 80% can be achieved. Moreover
in order to reduce the influence of manufacture accuracy and to increase the optical efficiency further
the central part of the bottom of the secondary lens which directly adhered to the solar cell is designed as a cone-shaped prism to collect the sunlight that doesn't reach the solar cell. 2010 SPIE.
