Abstract:
Space craft to solar system bodies must deal with multiple deviations under the in uence of gravity. The motion of satellite in one of the types of conic section strongly depends upon escape velocity. The goal of this paper is to nd the trajectory of satellite by analysing orbits eccentricity and or bital parameters. This paper also focuses on the derivation of general orbit equation from the base called Newtons law of motion and Newtons law of gravitation. N. Gayathri | S.

This article analyzes the classification and correlation between the longitudes of perigee and apogee with crescent moon visibility to understand the influence of these factors on the determination of the beginning of the lunar month. Primary data sources were obtained from calculated classifications of crescent moon visibility based on the longitudes of perigee and apogee from the years 1300H to 1600H for three locations: Sabang, Surabaya, and Merauke. Secondary data were sourced from Microsoft Excel. Data collection was conducted through documentation by studying the books Lunar Tables and P

Abstract:
This paper considers the effect of the solar radiation pressure on the motion of a satellite in an almostcircular low-Earth orbit. The formulation of the problem is due to the need to determine the effect of solar radiation pressure forces on the motion of light commercial Earth remote sensing (ERS) satellites with large surface areas (solar batteries and antennas). The goal is to determine the main regularities of this effect, construct reasonably simple and accurate estimates of changes in orbital parameters for the orbits under consideration, and clarify their physics (cause-and-effect rela

Abstract:
The Granat observatory was launched into a high apogee orbit on 1989 December 1 by a PROTON launcher. The initial Granat orbit had an apogee close to 200000 km and a perigee of 2000 km with an orbital period of 4 days. The satellite is entering the radiation belts for a few hours every orbit. Due to orbital evolution the perigee increased and the apogee decreased with time. After about 1.5 years of operation the perigee increased up to 20000 km. This has put the satellite completely outside of the proton radiation belts which makes the detector activation during the perigee passage negligible.

Apogee/Perigee Altitude History was used to graph apogee and perigee altitudes over KufaSat lifetime. The required change in velocity for maneuvers necessary to reentry atmospheric within 25 years was calculated.

Abstract:
The Hipparcos satellite was successfully launched by Ariane 4 flight 33, from French Guyana, on 8 August 1989. However, the apogee boost motor, designed to place the satellite into its intended geostationary orbit, failed to function, and the satellite was left in a highly elliptical transfer orbit. After a perigee raising manoeuvre, using the hydrazine propulsion system, the orbital parameters are approximately: apogee 35900 km, perigee 526 km, eccentricity 0.72, inclination 6.8°, orbital period 10h 40m.Operational procedures have had to be revised during the first weeks of satellite operatio

Abstract:
The combination of atmospheric drag and lunar and solar perturbations in addition to Earth’s oblateness influences the orbital lifetime of an upper stage in geostationary transfer orbit (GTO). These high eccentric orbits undergo fluctuations in both perturbations and velocity and are very sensitive to the initial conditions. The main objective of this paper is to predict the reentry time of the upper stage of the Indian geosynchronous satellite launch vehicle, GSLV-D5, which inserted the satellite GSAT-14 into a GTO on January 05, 2014, with mean perigee and apogee altitudes of 170 km and 3597

Abstract:
AbstractThe purpose of the guidance control is to release a payload into a prescribed target orbit (PTO) accurately. The parameters that determine an orbit are called orbital elements (OEs), which include the semi-major axis a, the eccentricity e, the argument of perigee $$\omega $$ ω , the inclination angle i, and the longitude of ascending node (LAN) or the right ascension of ascending node (RAAN) $$\Omega $$ Ω , where a and e can be converted to the perigee height $$h_p$$ h p and the apogee height $$h_a$$ h a . Thus, the guidance mission of a launcher is a typical optimal control problem with multi-terminal constraints, which requires complex iterative calculations. Considering various constraints in practical applications, such as the accuracy of inertial navigation systems and the performances of embedded computing devices (speed and storage capacity), guidance methods need to balance the mission requirements, hardware resources, and algorithm complexity. A variety of guidance methods has been developed with distinct era characteristics.

In the last decades, the growing in-orbit population of resident objects has become one of the main concerns for space agencies and institutions worldwide, and several Space Surveillance and Tracking (SST) related initiatives have been promoted to tackle this issue. Indeed, the presence of the so-called space debris may jeopardise the operative mission of active satellites, given that the possible impact with a space debris ranges from cumulative erosion of satellite surface to the possible satellite destruction, with the generation of thousands of additional pieces of debris and inevitable en
