Design of a Low - Orbit to Geostationary SatelliteLink for Maximal
نویسندگان
چکیده
| We examine the design of a communication link involving the data transfer from a small, low-orbit satellite to a ground station, but through a geostationary satellite. The advantage of this approach is that a single ground station , which tracks only the geostationary satellite, may be shared by a multiplicity of small satellites. Our goal is to select certain small satellite parameters { signaling rate, small satellite antenna beamwidth, modulation scheme, and coding scheme { which maximize the data throughput in bits per day. Our approach uses orbital simulations of this scenario together with theoretical analysis based on the channel capacity C and cutoo rate R 0. The throughput achievable by several practical coding schemes is also examined.

Displaced Geostationary Orbit Design Using Hybrid Sail Propulsion
Due to an increase in number of geostationary spacecraft and limits imposed by east-west spacing requirements, the geostationary orbit is becoming congested. To increase its capacity, this paper proposes to create new geostationary slots by displacing the geostationary orbit either out of or in the equatorial plane by means of hybrid solar sail and solar electric propulsion. To minimize propell...

متن کاملDetermination of the best-fitting reference orbit for a LEO satellite using the Lagrange coefficients
Linearization of the nonlinear equations and iterative solution is the most well-known scheme in many engineering problems. For geodetic applications of the LEO satellites, e.g. the Earth’s gravity field recovery, one needs to provide an initial guess of the satellite location or the so-called reference orbit. Numerical integration can be utilized for generating the reference orbit if a satelli...
