Instantaneous GNSS attitude determination: A Monte Carlo sampling approach
Xiucong Sun, Chao Han, Pei Chen
A novel instantaneous GNSS ambiguity resolution approach which makes use of only single-frequency carrier phase measurements for ultra-short baseline attitude determination is prop…
Rapid Satellite-to-Site Visibility Determination Based on Self-Adaptive Interpolation Technique
Chao Han, Xiaojie Gao, Xiucong Sun
Rapid satellite-to-site visibility determination is of great significance to coverage analysis of satellite constellations as well as onboard mission planning of autonomous spacecr…
Low-Earth Orbit Determination from Gravity Gradient Measurements
Xiucong Sun, Pei Chen, Christophe Macabiau +1
An innovative orbit determination method which makes use of gravity gradients for Low-Earth-Orbiting satellites is proposed. The measurement principle of gravity gradiometry is bri…
Gravity Gradient Tensor Eigendecomposition for Spacecraft Positioning
Pei Chen, Xiucong Sun, Chao Han
In this Note, a new approach to spacecraft positioning based on GGT inversion is presented. The gravity gradient tensor is initially measured in the gradiometer reference frame (GR…
