In this Tutorial, we will walk you through some possible steps taken in setting up a satellite project. Right now, we are going to design a mission for an Earth satellite.
Please read this article to learn how to access our satellite catalog.
After you logged into our catalog, import the Orbital parameters section. This section consists of a pre-made set of parameters and calculations to quickly calculate and visualise the satellite orbit. Change the Valis of the eccentricity, inclination, mean altitude, semi-major axis and true anomaly to the desired values. The other Valis will now be calculated automatically and altitude and velocity graphs will be generated for your orbit. The Orbital Parameters section has its own set of constants, but if required you can customise this to include constants from the Constants section, for instance to perform calculations for other planets.
Now that the mission outline is present in Valispace, we can start importing components into the satellite. From the mission requirements we know what the required thrust is to get into a good orbit. With this information, we go to the propulsion section and import two 22N Bi-propellant hydrazine engines into the design. The component trees are setup in such a way that it is always easy to find the required components. The 22N thrusters can be found by navigating to:
Satellite>Propulsion>Thrusters>10N_100N>22N_Bi_MMH_thruster. We also know that using this bi-propellant engine will require two 7-liters propellant tanks, so we will also import these.

Besides the propulsion subsystem, we also have requirements for the power, attitude control and thermal subsystems. From the respective sections we import solar arrays and batteries, attitude sensors and actuators and a cryocooler. We could however not find the correct battery in the catalog, so instead of using an off-the-shelf battery from the catalog, we import a battery and change the Valis to our custom specifications.
Lastly, we want to make a custom design for the side panels of the satellite. To do this, we create a new component in our project. Since we know that we want to use Titanium for this, but don't want to manually create all the Valis into Valispace, we go to the constants section of the catalog and import the
Ti_6Al_4V annealed Titanium alloy from the material properties tree. With the imported parameters, we can easily size our side panels according to the requirements.
Start Building your own Satellite
Using the examples above, you should now be able to use the catalog to design your own satellite! If you have further questions or suggestions for improvements, please feel free to contact us.
PowerUserTip: Still cannot be bothered to design your own satellite? You can also simply import a pre-made satellite bus from the structure subsystem!
