任红飞 魏子卿 . 相对论框架下脉冲星导航的2PN观测方程研究[J]. 测绘学报, 2014 , 43(10) : 1025 -1031 . DOI: 10.13485/j.cnki.11-2089.2014.0142
Advance of theory and applications in the pulsar navigation are first briefly reviewed, then considering the angular momentum and quadruple moment of celestial bodies in
solar system, the 2PN observation equation for pulsar navigation is derived, and the numerical simulations for 2PN relativistic effects are analyzed. Results show that the
relativistic effects of angular momentum and quadruple moment of celestial bodies in solar system are about 10-13 s, the light ray bending due to the sun is less than 1 ns, the
light ray bending due to the Jupiter is 10-18 s, which is the largest among the solar system planets.
Key words: pulsar navigation; observation equation; relativistic effects
