# High level description Nyx uses the hyperdual representation of an orbit to compute the partial derivatives of orbital elements with respect to the Cartesian elements. At the moment, the...
For this task, the idea is to demonstrate that Nyx supports high fidelity estimation of lunar orbits. Idea: grab one of the definitive ephemeris files from NASA PDS for LRO,...
# High level description Ground stations have biases, which are currently modeled as [first order Gauss Markov](https://rustdoc.nyxspace.com/nyx_space/od/noise/gauss_markov/struct.GaussMarkov.html) processes. With a reasonably high bias, the OD results are quite noisy because...
# High level description Kedro has a [data catalog](https://docs.kedro.org/en/stable/data/data_catalog.html) concept, which is absolutely fantastic to use. In a way, this is what the `ExportCfg` does but only for _saving_ data,...
# High level description The first part of this work will include creating, refactoring, and re-enabling the Python interface in Nyx, which was removed in #305 for the sake of...
# High level description At the moment, OD only support range and Doppler measurement, simultaneous or not. In practice, especially in LEOP, we may want to use azimuth and elevation...
# High level description Issue #326 will support estimation of the ground station biases. Although important, it's possible that one may increase the measurement noise quite high in order to...
# High level description There are currently some low fidelity drag models. In the past few years, these drag models have greatly improved. This ticket should support one of the...
# High level description Large spacecraft may be affected by albedo modeling. This is not currently supported in Nyx, but it should be and it's pretty straightforward. Migrated from https://gitlab.com/nyx-space/nyx/-/issues/201...
# High level description Nyx can compute the [eclipsing (with penumbra)](https://rustdoc.nyxspace.com/nyx_space/cosmic/eclipse/fn.eclipse_state.html) and the [line-of-sight visibility](https://rustdoc.nyxspace.com/nyx_space/cosmic/eclipse/fn.line_of_sight.html). This [algorithm is derived in the MathSpec](https://nyxspace.com/nyxspace/MathSpec/celestial/eclipse/) and its implementation is verified in the ["GEO...
