s = linkStatus(lnk)
returns a matrix of logicals representing the link closure status history
s of each link in the vector link. The rows of
the matrix correspond to the link objects in link and the columns
correspond to the time sample.
s = linkStatus(lnk,timeIn)
returns a column vector of status s of each link in the vector
link at the specified datetime timeIn. Each
element of s corresponds to a link in link. If no
time zone is specified in timeIn, the time zone is assumed to be
UTC.
[s,timeOut] = linkStatus(___)
returns the link closure status and the corresponding times in Universal Time Coordinated
(UTC).
lnk — Link analysis Link object vector | Link object scalar
Link analysis object, specified as a Link object
vector or scalar.
timeIn — Time at which output is calculated datetime scalar
Time at which the output is calculated, specified as a datetime scalar. If
no time zone is specified in timeIn, the time zone is assumed to be
Universal Time Coordinated (UTC).
Link closure status, returned as a matrix of logical values representing the link
closure status history s of each link in the vector
link. The rows of the matrix correspond to the link objects in
link and the columns correspond to the time sample. The status at
a given instant is 1 (true) if the link between
first and last node is closed. The link between the first and last node is closed when
the link between each individual pair of intermediate adjacent nodes in the Sequence
property of the link is closed.
For a given pair, the link is considered to be closed when both nodes belong
to the same satellite or ground station.
Otherwise, the link between the pair is closed if the directionality is from a
transmitter to a receiver and the energy per bit to noise power spectral density
ratio (Eb/No) at the receiver is greater than its
RequiredEbNo.
Additionally, if a given node is attached to a ground station directly or via
a gimbal, the elevation angle of the adjacent node with respect to the ground
station must be greater than or equal to its MinElevationAngle.
timeOut — Time samples of output link status scalar | vector
Time samples of output link status, returned as a scalar or a vector. If time
history of link status is returned, timeOut is a row vector.
