An Introduction to the Mathematics and Methods of Astrodynamics
Cotangential Transfer Orbits As a first guess it would seem reasonable to
suppose that the optimum transfer orbit would be tangent to both the initial orbit
through P1 and the final orbit through P2. When the transfer angle 6 is 180° and
the ...

THE PROBLEM OF
COTANGENTIAL TRANSFER.
Solution of the optimum cotangential transfer between two coplanar, noncoaxial, elliptical orbits is presented.
Nguyen X. Vinh, COLORADO UNIV BOULDER., 1965
Other investigators have tried to solve this transfer problem by specializing the
transfer to be a 180-deg transfer or to be cotangential. The 180-deg transfer
restricts the departure and arrival points to be separated by 180 deg in central
angle.

Orbital Motion, Fourth Edition
A rocket moving in the inner orbit uses its motor to provide a tangential velocity
increment 1-6 times the velocity increment required to take the vehicle from the
inner orbit by a cotangential elliptic transfer orbit as far out as the outer orbit.

On the other hand (i) implies by (24) (and (Nomizu-Sasaki, 1993, Lem. 1.2)) T = 0
and now by (30) C4 = 0. Thus (iii) and (i) are equivalent. Since the centroaffine
cotangential frame is orthonormal with respect to g, condition (v) is equivalent to:

Industrial Applications of Genetic Algorithms
restricted to two classes of transfer orbits - 180° transfer and cotangential transfer.
The 180° transfer was defined as a transfer where the arrival and departure
points are separated by 1 80 degrees and not necessarily at the apses of either
orbit ...

8-3-8 Cotangential transfer between noncoaxial ellipses The preceding analysis
dealt with two types of elliptic transfer between two elliptic orbits: the cotangential
coapsidal transfer and the intersecting transfer, both between two coaxial orbits; ...

Introduction to Space Dynamics
Cotangential Transfer between Coplanar Circular Orbits Transfer between
coplanar circular orbits can be effected by an elliptic orbit with perigee and
apogee distances equal to the radii of the respective circles, as shown in Fig.
