Analysis of Turning Total Life Requirement for Cross-link Steerable Antenna Based on Observation Geometry Method
摘要
Abstract
The turning total life requirement is very important for designing a cross-link steerable antenna.By introducing a simulation method based on observation geometry theory,the evolution of the constellation,the attitude controlling of satellites and the revolution of steerable antennas could be simulated without the complicated dynamical simulation.As an example,the method is applied to a Walker-δ constellation and its cross-link steerable antennas,and then the numerical analysis yields the turning total life requirement for antenna's tow-axis.The method might be applied in designing for long life and high reliability,and for programming a life test.The method is universal for other types of constellations or other cross-link terminal devices which depend on steerable two-axis for target tracking.关键词
