1. A method, comprising:
receiving user input parameters associated with a drilling operation of a borehole;
receiving system input parameters, wherein the system input parameters include sensor parameters, where a drilling assembly is at a downhole end of the borehole, the sensor parameters are used to extrapolate an actual borehole trajectory, and the system input parameters are received in real-time or near real-time;
determining corrections to the actual borehole trajectory, wherein the corrections describe drilling parameter changes to align the actual borehole trajectory with a planned borehole trajectory;
optimizing the corrections to generate revised corrections, wherein one or more optimizations are selected to be applied to the corrections, each optimization of the one or more optimizations utilizes a respective optimization range parameter, where the optimizing includes adjusting at least one optimization of the one or more optimizations, when the at least one optimization is not satisfied, by using the respective optimization range parameter or modifying a weighting parameter of the at least one optimization, or by removing the at least one optimization from the one or more optimizations, and a minimum of one optimization in the one or more optimizations is a non-steering optimization for a drill bit; and
determining one or more results utilizing the revised corrections, the user input parameters, or the system input parameters, wherein the results specify updated instructions to the drilling assembly thereby changing a trajectory of the drilling assembly.
