CollisionMonAlg:
--------------------------------------------------------------------------
Collision monitoring algorithm for maneuvering spacecraft.
Discretizes orbit according to input time and anomaly vectors. Handles
high eccentricity and maneuvers input through acceleration vector.
Since version 7.
--------------------------------------------------------------------------
Form:
[prob, dMin, Shat, xhat] = CollisionMonAlg( y, t, M, nu, accel, aDiff, d )
--------------------------------------------------------------------------
Inputs
------
y (6,m) Relative state(s)
t (1,n) Time vector [s]
M (1,n) Mean anomaly vector
nu (1,n) True anomaly vector
accel {m} Accelerations due to maneuvers
aDiff (3,m) Differential accelerations
d : Algorithm data structure
.el0
.eRef Eccentricity
.MRef Mean anomaly
.initBounds Error in measurement (6,1) [km, km/s]
.scalev Sigma for measurement noise
.lenSC Spacecraft length [m]
.Pmin Probability of scalev
.Ssc Spacecraft hard-body sphere
.S0 Initial ellipsoid
Outputs
--------
prob {n}(1,:) probability of collision
d {n}(1,:) minimum distance between spacecraft position ellipsoids
xhat {n}(6,:) xhat, ellipsoid centers
Shat {n}(6,6,:) Shat, ellipsoid size matrices
