Approximation of artificial satellites' preliminary orbits: the efficiency challenge

Arroyo Martínez, Víctor; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón (Elsevier, 2011-10)

In this paper the problem of the determination of the preliminary orbit of a celestial body is studied. We compare the results obtained by the classical Gauss's method with those obtained by some higher-order iterative ...
Artificial satellites preliminary orbit determination by the modified high-order Gauss method

Arroyo Martínez, Víctor; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Penkova Vassileva, María (Taylor & Francis Ltd, 2012)

In recent years, high-order methods have shown to be very useful in many practical applications, in which nonlinear systems arise. In this case, a classical method of positional astronomy have been modified in order to ...
Derivative-free high-order methods applied to preliminary orbit determination

Chicharro López, Francisco Israel; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón (Elsevier, 2013-04)

From position and velocity coordinates for several given instants, it is possible to determine the orbital elements of the preliminary orbit, taking only into account mutual gravitational attraction forces between the Earth ...
New and improved orbits of historical comets: Late 4th and 5th century

Martínez Uso, María José; Marco, F.J.; Sicoli, P.; Gorelli, R. (Elsevier, 2022-09-15)

[EN] Since as early as the 19th century, many scholars have devoted themselves to the calculation of sets of orbital elements for particular historical comets. In many cases, these studies have led to proposing orbits that ...
