原题:选择合适的卫星发射地发射卫星,对提高运载效率、节省燃料等方面都有影响(特别是对同步卫星的发射)。如果在地球表面纬度为Φ处发射一颗绕地球表面运行的人造卫星,假设地球可视为质量均匀分布的球体,已知地球自转的角速度为ω,地球半径为R,地球表面处的重力加速度为g,卫星质量为m,则至少要给 The original question: Choosing the right satellite launch site to launch satellites has an impact on improving transport efficiency and saving fuel (especially for the launch of geostationary satellites). If a satellite running around the surface of the Earth is launched at a latitude of Φ on the surface of the Earth, assuming that the Earth can be regarded as a sphere of uniform mass distribution and that the angular velocity of rotation of the Earth is ω and the radius of the Earth is R, the gravitational acceleration at the Earth's surface For g, satellite mass m, then at least give
