Satellite Servicing Databases

This is the fourth installment of our  SpaceFund Reality (SFR) rating, focused on satellite servicing.

If you haven’t already, please consult our SpaceFund Reality (SFR) ratings page to learn more about the rating, its purpose, and the underlying formula, as well as to view a complete list of the SpaceFund sectors of interest. 

How to Use This Table

Sort: Click on the column heading to sort A-Z; click again to sort Z-A.

Search: To search within the entire table, simply type your query into the search area at the top right of the table. If you’d like to search within a specific column, use the search box at the bottom of that column.

Download: You can download this table as an Excel or CSV file by using the icons at the top of the table. You can also print the table.

Screen Size: The database is too big to fit on most screens, so you’ll need to use the scroll bar at the bottom of your screen to scroll right to see additional columns, and continuing scrolling down to see all companies. 

Important Note (Alpha Sort Columns vs Numeric Sort Columns): In the Occupancy, Floor Area, and Volume columns, any figure listed as a “0” is simply a placeholder for unavailable data. This is due to the nature of this table format, and to ensure that the columns sort properly, a numeric character must be included in each cell. So, for example, if a company’s habitat is listed to have a Floor Area of “0” this simply means that this information is not publicly available and the “0” acts as a replacement for “N/A”.  

The Funding column is set to sort alphabetically. Since this column contains alphabetic characters in some cells, it will sort alphabetically, not numerically and so the “-” character has been used to represent unavailable data. All other columns in the table will also sort alphabetically.

Important Note (Companies not Products): This database, and the SpaceFund Reality ratings, are based on COMPANIES, not specific products or technologies. 


How to Provide Updated Data

Have we missed your company? Do you feel that your company should have a different rating? Is the listed data inaccurate or outdated? Do you see missing data for your company? The best way to update your information in this database is to reach out to us directly to provide additional information about your technology, management team, funding history, and company progress. We are also eager to learn about any additional data sources that can help us in our ongoing research, so please feel free to share any resources you know of with our team.

Updates will be published on approximately a monthly basis.

SpaceFund Sectors of Interest

SpaceFund is interested in a number of sectors of the space economy, specifically Transportation, Communication, Human Factors, Supplies, and Energy. In the coming months we will post SFR ratings for companies from all of these sectors, providing a robust overview of the state of frontier-enabling companies across the industry. To begin, we have created an SFR database for the Earth-to-Space sub-sector of Transportation (launch), as well as a database for the Beyond Earth Orbit sub-sector of Communication, and the Habitats sector of Human Factors. Please check back frequently to view new sub-sector databases, and sign up to receive our emails to be notified of each new release.
