The following .mat files

Type1.mat
Type2.mat
Type3.mat
Type1drift.mat
Type2drift.mat
Type3drift.mat
Type1clean.mat
Type2clean.mat
Type3clean.mat

are Matlab files containing propagated trajectories of formation flight in the geostationary orbit.
These files can be loaded to Matlab and plotted by running the script

plotter.m

The variables contained in the .mat files are the following

a_grav: time-sequence of gravitational acceleration on all satellites
a_MBP: time-sequence of luni-solar gravitational acceleration on all satellites
a_SRP: time-sequence of solar radiation pressure acceleration on all satellites
errH: measured relative orbit error
Fa: actuation acceleration delievered
Fa_req: actuation acceleration required
H: relative trajectory in Hill frame
measH: measured relative trajectory in Hill frame
RJ2000: rotation matrix from Earth-Fixed frame to J2000 frame at 20 Feb 2017
t: time sequence
targH: reference relative orbit
Tout_d: thruster outputs
x: trajectory in Earth-Fixed frame
xJ2000: trajectory in J2000 frame

Information about geographic location of data collection: University of
Southampton, U.K.

Date that the file was created: February 2017
