fast dynamic orbit determination of leo satellites using the legendre polynomial approximation
the low earth orbiting (leo) satellites are widely used for geosciences applications. for most applications, precise orbital information of the satellites is required. a combination of the in suite observations and dynamic orbit yields the optimum solution. in order to obtain the combined optimal solution, one needs to analytically or numerically propagate the state vector epoch by an epoch bas...
متن کاملthe improvement of reduced-dynamic orbit of leo satellites using best-fitting reference orbit
satellite orbit determination is a method of determining the state vector, i.e., position and velocity, of a low earth orbiting (leo) satellite or interplanetary spacecraft. during the past two decades, many satellites with various applications including geodetic applications have been launched at low altitudes. for instance, topex / poseidon, champ, grace and goce are the examples of the geode...
متن کاملPaper AAS 03-664 ACCURACY AND SPEED EFFECTS OF VARIABLE STEP INTEGRATION FOR ORBIT DETERMINATION AND PROPAGATION
In this paper the fixed step Gauss-Jackson method is compared to two variable step integrators. The first is the variable step, variable order Shampine-Gordon method. The second is s-integration, which may be considered an analytical step regulation. Speed tests are performed for orbit propagation with the integrators set to give equivalent accuracy. The integrators are also tested for orbit de...
متن کاملPrecise Orbit Determination for Low Earth Orbit Satellites
The precise orbit determination problem is to accurately determine the position and velocity vectors of an orbiting satellite. In this paper we review the general contents of the orbit determination process, with particular emphasis on Low Earth Orbit (LEO) satellites. The different orbit determination approaches and the different force models contained within are briefly discussed. The two mai...
متن کاملRSVP for LEO satellites
The Internet Engineering Task Force (IETF) is working on extending the traditional TCP/IP model for supporting multimedia and real-time applications on the Internet. Thus, new protocols have been developed such as the Resource Reservation Protocol (RSVP). At the same time, there has been a growing interest in using Low Earth Orbit (LEO) satellites. In the near future, when the Internet with mul...
