+position and velocity of an earth-orbiting satellite, given the satellite’s
+@acronym{TLE, Two-line element set} orbital elements from a source like
+@url{CelesTrak, https://celestrak.org/}.
+
+It implements the most recent version of @acronym{SGP4, Simplified General
+Perturbation models}, and is regularly run against the SGP4 test suite to make
+sure that its satellite position predictions agree to within 0.1 mm with the
+predictions of the standard distribution of the algorithm. This error is far
+less than the 1–3 km/day by which satellites themselves deviate from the ideal
+orbits described in TLE files.")
