libgs.hardware.RotatorBase

class libgs.hardware.RotatorBase

Base class for any rotator hardware interface

Any rotator interface must derive from this class and implement the interface methods:

• get_azel()
• set_azel()

Additionally you should set the name attribute to something descriptive, and change the configuration attribute parameters as appropriate:

• STOWED_AZ
• STOWED_EL
• BEAMWIDTH
• MAX_AZ
• MIN_AZ
• MAX_EL
• MIN_EL
• SLEW_TIMEOUT

Methods

azel_err(az, el)	Returns the error in degrees between the current pointing and a specified az/el
azel_to_antenna_angles(pdat[, cont_track_method])	From a table of az/el pointings, compute a new table that minimises the amount of movements while keeping the off-pointing within the antenna beamwidth
get_azel()	Get current az, el pointing
in_pos([az, el])	Check if antenna is in position.
set_azel(az, el, block)	Set new az, el pointing
stow([block])	Stow antenna

Attributes

BEAMWIDTH	Antenna beamwidth
MAX_AZ	Maximum allowd azimuth command
MAX_EL	Maximum allowed elevation command
MIN_AZ	Minimum allowed azimuth command
MIN_EL	Minimum allowed elevation command
SLEW_TIMEOUT	Slewing Timeout (s)
STOWED_AZ	Stowed azimuth position
STOWED_EL	Stowed elevation position
az	Return / Set current azimuth
azel	Return / Set current (azimuth, elevation).
cmd_az	Return / Set commanded azimuth
cmd_el	Return / Set commanded elevation
el	Return / Set current elevation
name	Property for getting/setting the radio name.
