% Multispacecraft orbit model designed to work with ode113.
You can include aerodynamic, radiation pressure and thrust models. Sun,
earth, and moon perturbations are computed if the planet (Earth or
Moon) is given. Uses SunV1 and MoonV1 for ephemeris.

Form:
d = FOrbitMultiSpacecraft % data structure
xDot = FOrbitMultiSpacecraft( t, x, d )
--------------------------------------------------------------------------
------
Inputs
------
t Time
x (7*n,1) The state vector [r1;v1;m1;r2;v2;m2;...]
d (:) Data structure array
.jD0 (1,1) Julian date at start
This is only needed for planetary disturbances
and if a gravity model is entered:
.planet (1,:) Planet name, 'earth', 'moon'
These are optional:
.thrusterModel (1,:) Thrust function handle
.thrusterData (.) Thrust data structure
.opticalModel (1,:) Optical function handle
.aeroModel (1,:) Aero function handle
.surfData (.) Surface data structure
.gravityModel (.) Gravity model structure;
default is point-mass.
The following are only needed if you want J70, otherwise
AtmDens2 will be used.
.atm.aP (1,1) Geomagnetic index 6.7 hours before the computation
.atm.f (1,1) Daily 10.7 cm solar flux (e-22 watts/m^2/cycle/sec)
.atm.fHat (1,1) 81-day mean of f (e-22 watts/m^2/cycle/sec)
.atm.fHat400 (1,1) fHat 400 days before computation date

Outputs
-------
xDot (7*n,1) The state vector derivative [v1;r1Dot;m1Dot...]
