asteRisk: Computation of Satellite Position

Provides basic functionalities to calculate the position of satellites given a known state vector. The package includes implementations of the SGP4 and SDP4 simplified perturbation models to propagate orbital state vectors, as well as utilities to read TLE files and convert coordinates between different frames of reference. Several of the functionalities of the package (including the high-precision numerical orbit propagator) require the coefficients and data included in the 'asteRiskData' package, available in a 'drat' repository. To install this data package, run 'install.packages("asteRiskData", repos="")'. Felix R. Hoots, Ronald L. Roehrich and T.S. Kelso (1988) <>. David Vallado, Paul Crawford, Richard Hujsak and T.S.
