TY - JOUR AU - Rahoma, Walid Ali PY - 2013 TI - Lunisolar Invariant Relative Orbits JF - American Journal of Applied Sciences VL - 10 IS - 4 DO - 10.3844/ajassp.2013.307.312 UR - https://thescipub.com/abstract/ajassp.2013.307.312 AB - The present study deal with constructing an analytical model within Hamiltonian formulation to design invariant relative orbits due to the perturbation of J2 and the lunisolar attraction. To fade the secular drift separation over the time between two neighboring orbits, two second order conditions that guarantee that drift are derived and enforced to be equal.
