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="https://rafael-ayala.github.io/drat/")'. Felix R. Hoots,
