ABSTRACT A method to predict satellite orbits in a stand‐alone consumer‐grade GNSS
navigation device is presented. The motivation for this work was to reduce the startup time of …

In this paper, a new method for fault diagnosability research based on information geometry
is proposed. The problem of the diagnosability evaluation of dynamic system faults is …

Abstract BeiDou Navigation Satellite System (BDS) is composed of satellites in
geostationary Earth orbit (GEO), medium Earth orbit (MEO) and inclined geosynchronous …

GNSS satellite orbits can be predicted by integrating the satellites' equation of motion. If the
prediction is done in a consumer grade positioning device, a simplified version of the …

In self-assisted GNSS the orbit of a satellite is predicted by solving the differential equation
that models its motion. Our motion model includes the most important forces: Earth's gravity …

Traditional GPS receivers usually take a long time to obtain their first position solution in the
cold start mode. This paper presents a method for assisting the cold start of GPS receivers …

As a sensor for standalone position and velocity determination, the BeiDou Navigation
Satellite System (BDS) receiver is becoming an important part of the intelligent logistics …

In recent years, the number of satellites and debris in space has dangerously increased. For
this reason, it is indispensable that tracking and orbit prediction of these objects is performed …

In Chapter 1, the general concept of orbit determination problem was discussed using a
dynamics model that uses a set of perturbation forces affecting the motion of the satellite …

NavIC is a newly established Indian regional Navigation Constellation with 3 satellites in
geostationary Earth orbit (GEO) and 4 satellites in geosynchronous orbit (GSO). Satellite …
