Precise Real-Time Navigation of LEO Satellites Using a Single-Frequency GPS Receiver and Ultra-Rapid Ephemerides
Xiucong Sun, Chao Han, Pei Chen
Precise (sub-meter level) real-time navigation using a space-capable single-frequency global positioning system (GPS) receiver and ultra-rapid (real-time) ephemerides from the inte…
Autonomous Orbit Determination Using Epoch-Differenced Gravity Gradients and Starlight Refraction
Pei Chen, Tengda Sun, Xiucong Sun
Autonomous orbit determination via integration of epoch-differenced gravity gradients and starlight refraction is proposed in this paper for low-Earth-orbiting satellites operating…
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…
Real-time kinematic positioning of LEO satellites using a single-frequency GPS receiver
Pei Chen, Jian Zhang, Xiucong Sun
Due to their low cost and low power consumption, single-frequency GPS receivers are considered suitable for low-cost space applications such as small satellite missions. Recently,…
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…
