Availability analysis of GNSS signals above GNSSs constellation
The combination of main and side lobe signals and compatibility of multiple constellations can increase the number of visible satellites, improve the geometry configuration, reduce GDOP, and thus improve the availability of GNSS signals. Expand
Récepteur de navigation reconfigurable pour applications spatiales
L’orbite d’un satellite autour de la terre est perturbee en permanence par differents facteurs, tels que la variation du champ gravitationnel et la pression du vent solaire. La derive de la positionExpand
High Fidelity Satellite to Satellite Tracking toolkit (HFSST) for Navigation Mission Design
The HFSST “High Fidelity Satellite to Satellite Tracking toolkit” is a tool for space navigation mission analysis design that includes orbital model, attitude model, and signal model as well as visualization module which make it suitable to develop elaborated analysis of satellite navigation missions whether near Earth or deep into space.

GNSS Performance Research for MEO, GEO, and HEO
This paper analyzes the GNSS satellite visibility and PDOP performances for 6 space users, including two GEO, one MEO, and three HEO satellites and concludes that the higher the space user flies, the more important role multi-GNSS application plays. Expand
Global Positioning System Navigation Above 76,000 km for NASA's Magnetospheric Multiscale Mission
Past and ongoing high-altitude GPS research efforts at NASA GSFC and elsewhere are described, details on the design of the MMS GPS navigation system are provided, and on-orbit performance data from the first phase are extrapolated to predict performance in the second phase. Expand
The data processing and analysis for the CE-5T1 GNSS experiment
Investigations indicate that the PDOP value increases up to 1.4 times and the SPP accuracy deteriorates by more than 142% if satellite R06 is excluded in the positioning computation, and noisier GLONASS pseudorange data should be properly weighted in order not to deteriorate the positioning accuracy.

Autonomous navigation scheme of lunar relay satellite based on weak GNSS signals
This paper investigates the autonomous navigation scheme of Lunar Polar Orbit Relay Constellation based on weak GNSS signals and increases the receiver sensitivity, which improves the satellite visibility and makes contribution to the scheme of orbit control system in the subsequent series of lunar exploration satellites.

Coordinate and Time-frequency Support of a Spacecraft Flight by Means of Autonomic Navigation Using Sigma-point Kalman Filter Algorithm
Estimates of a spacecraft current coordinate and velocity estimates are formed by the navigation calculator on the bases of pseudo range and pseudo velocity measurements taken in the regime of navigation signals delay and Doppler frequencies tracking under the condition of the receiver noise.
