Detailed Description

Provides the schedule for a slew to a particular point on the celestial sphere.

This is done by calculating a target phi and theta, and moving directly to those angles by independent motions in the two axes. This is in contrast to the initial implementation, which planned a great-circle route and followed that.

Member Function Documentation

bool SlewSchedule::schedule_ok ( ) const

inline

Is this a feasible schedule? Return false if it would end up in the empty sector.

ms_t SlewSchedule::step ( double  current_phi, double  current_theta, ms_t  current_time  )

virtual

Take a step on the slewing path.

Phi is the longitudinal coordinate, theta is the altitude (so increasing towards the zenith). Note that, like the outputs from the Kalman filters, these arguments should not be normalised into [-pi,pi].

Implements Schedule.
