Detailed Description

Activity: Driving the telescope to a given AzAlt location.

Constructor & Destructor Documentation

DriveAzAlt::DriveAzAlt	(	TelescopeController *	tc,
		State *	state,
		double	az,
		double	alt
	)

Provide the target to drive to.

Note that the coordinates are given in AzAlt.

Parameters

tc	a pointer to the telescope-control object
state	the current state of the telescope pointing
az	the target azimuth, in radians east from north
alt	the target altitude, in radians towards the zenith (must be in [-pi/2,+pi/2])

Member Function Documentation

ms_t DriveAzAlt::start ( ms_t  now )

virtual

The activity will be started by the main loop calling the start function.

Returns

the time at which the activity should next be poked (return TIME_NEVER to avoid being poked again).
