This is UFT378 Sections 1 and 2, with Section 3 sketched in as usual for co author Dr Eckardt’s computation and graphics. A new theory of orbits is developed with the force, field and potential equations of ECE2. Counter gravitation is incorporated into the theory at the end of Section 2, following UFT318 and UFT319. The theory gives the possibility of zero gravitation and counter gravitation on the classical level. The theory can be quantized straightforwardly. It is shown that orbits can be aether engineered.
