Or, your collection may consist of groups of satellites of different build configurations. When Satellite Collection entries have an associated reference satellite, they inherit all non-trajectory settings of the reference when they are used in analyses.įor example, if you wanted to determine which elements of the collection were lit during visibility periods to a ground station, you could set a lighting condition constraint on a reference satellite associated with the collection and then run a Deck Access operation. The Satellite Collection object provides the option to associate one or more reference satellite(s) with all or part(s) of the collection.

For example, you can create a collection of all the Starlink satellites in the public catalog, or you can create a collection of all objects in Low Earth Orbit.Īll Starlink Satellites, can you spot the satellites from a recent launch? What about all the other settings and behaviors that normal satellites have? Can I control those as well? You can put any combination of satellites you want into it. While large (dare we say mega?) constellations are certainly of interest to the community, we designed the Satellite Collection to be more versatile.

We have performed tests involving over 600,000 orbiting objects! How many orbiting objects do you have?ĭual shell Walker Constellation containing upwards of 600,000 satellites Why a “Collection” instead of a “Constellation”? On the other hand, using individual satellite objects enables you to completely customize configurations on a per satellite basis, exposes more detailed orbit propagation options, and provides access to more extensive reporting, graphing, and visualization options.

Maintain multiple configurations of a proposed large constellation design in a single scenario.

Efficiently set graphical properties for all (or many) of your satellites at once.

Save and load your scenario in a fraction of the time required when using individual satellites.

Reduce the number of entities in the object browser.

Grouping satellite definitions together inside a collection enables you to: You can use the Satellite Collection object when you do not need custom configurations (beyond the trajectory) for each of the satellites in your scenario. In general terms, the Satellite Collection object enables you to perform the types of analyses that STK is famous for on large numbers of satellites in an efficient manner.Ĭoverage analysis of a ridiculous constellation design What are the benefits of using a Satellite Collection over individual satellites? While the Satellite Collection object has limited reporting and visualization capabilities, it is integrated with traditional STK analysis tools and capabilities such as Deck Access, Coverage, Communications, and Conjunction Analysis.

Using your own custom orbit elements or ephemerides.

As a subset of the public space catalog (or the entire space catalog).

As a multi-shelled Walker constellation.

You can define the entries in the collection in three ways: The Satellite Collection object provides an efficient mechanism for defining and managing large numbers of satellites without cluttering up your scenario with tons of individual satellite objects.

Visualizing the full space catalog is easy So, what does the Satellite Collection object do?

Perhaps a little simulated Q&A (we do produce simulation software after all) will provide some additional insight into the utility of the Satellite Collection object. The Satellite Collection - which was a preview feature in STK 12.2 - is all grown up and is now a standard feature in STK 12.4! You might be asking yourself: What is a collection object and what do I use if for? The Satellite Collection object is a container of satellite orbit definitions that simplifies the analysis and visualization of problems involving large numbers of satellites. I got a whole lotta of satellites in my collection, wanna see it? Introducing the new Satellite Collection object!
