Spacecraft.MltAscendingNodeError(Variable) Method

Top

Description

Returns the offset from a user-defined Ascending Node Mean Local Time (MLT) crossing versus the Spacecraft's MLT crossing at the Ascending Node. This method is primarily used for Sun-Synchronous orbits: where the orientation of the orbit is fixed with respect to the Sun and the Spacecraft has a fixed nodal crossing time requirement. This method requires a single argument, which defines the fixed nodal MLT crossing. This base MLT is used to evaluate the difference between the engineer's requirement and the Spacecraft nodal crossing time.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
