SPAT R2015a (4.3.0 beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• Added ground station access plot to ground section

Bugs fixed

• Upon mission value on the summary table, the remaining values were shifted
• The plots of power on Z and X axes panels were exchanged between + and -

SPAT R2015a (4.2.0 beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• Added to the unit profile, a label to show the average power consumed by the satellite
• Added to the unit profile a new button that allows plotting the power profile consumption table
• In the main windows, a new button added that presents summary table with the most important results of the analysis

Bugs fixed

• Minor fixes to the default values
• Exit button removed because closing now triggers the same callback Exit did
• The link budget dialog was not recovering the modulation scheme
• The 'plot ground track' in 'mission ground track' was plotting the local time in the legend instead of GMT.

SPAT R2015a (4.1.1 beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• Added a ground track prediction for the satellite mission that is being designed
• Added a field to include the name of the satellite
• Passages reports also include the average passage over the configure time of propagation
• Passages reports also include info about the elevation and min, max passage duration
• Added to the orbit propagator tool the ability to select ground stations and to plot the elevation of the passages
• Added to the link budget the 'compute' button that calculates and shows the link budget table
• Battery configuration dialogs changed

Bugs fixed

• The ground station min elevation angle is removed as it is not used during the ground track calculations
• The passages report was not printing correctly the pass duration when above 1h
• Ground tracking of the mission (not TLE-based) was not computing the passages hours correctly as LTAN was not taken into account

SPAT 4.0.1 (beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• Link budget is now calculated for the worst case, apogee and 0 to 90 degrees elevation

Bugs fixed

• Link budget was not working when changed to SGP4 propagator.
• The mission configuration had satellite altitude as orbit input parameter instead of semi-major-axis.
• When the user cancelled some actions (e.g. directory selection) the error was not handled properly
• Passages were not properly calculated for non circular orbits.
• As we changed the ground tracking functions, the link budget was left with a bug calling a non-existing function

SPAT 4.0.0 (beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• Ground track and ground visibility is now based on TLE files.
• TLE files are downloaded/upgraded automatically
• Some GUI elements moved to more convinient places

Bugs fixed

• ground track and passages are now based on SPG4 propagator and TLE information

SPAT 3.0.6 (beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• Windows and MacOS packages include readme.txt with some info about the installation of MATLAB MCR
• Windows app is distributed as auto-exe package
• MacOS package contains a script run_SPAT.sh that sets up the MCR environment. This is auto-generated from MATLAB

Bugs fixed:

• Passage time calculation was off due to wrong earth radius

SPAT 3.0.5 (beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.

New features

• SPAT is a satellite power and mission design/analysis tool.

Bugs fixed:

• Ground track was not working for all satellite inclination angles.

SPAT 3.0.3 (beta) released

SPAT is a satellite power and mission design/analysis tool. Developed in MATLAB (MCR required) and currently available for Windows and MacOs.
