A Case Study on the Effect of Atmospheric Density Calibration on Orbit Predictions with Sparse Angular Data

Remote Sensing, 2023
Accurately modeling the density of atmospheric mass is critical for orbit determination and prediction of space objects. Existing atmospheric mass density models (ADMs) have an accuracy of about 15%.

Extension of the sun-synchronous Orbit [PDF]

, 2010
Through careful consideration of the orbit perturbation force due to the oblate nature of the primary body a secular variation of the ascending node angle of a near-polar orbit can be induced without expulsion of propellant.

In-orbit Calibrations of the Ultraviolet Imaging Telescope [PDF]

The Astronomical Journal, 2017
Abstract The Ultra-Violet Imaging Telescope (UVIT) is one of the payloads in ASTROSAT, the first Indian Space Observatory. The UVIT instrument has two 375 mm telescopes: one for the far-ultraviolet (FUV) channel (1300–1800 Å), and the other for the near-ultraviolet (NUV) channel (2000–3000 Å) and the visible (VIS) channel (3200–5500 Å ...
