Small Satellite Cost Model

The Small Satellite Cost Model is the result of over 20 years of Aerospace study. Traditional models are based on larger space systems and tend to drastically over-predict the development costs of smaller (under 1000 kg) satellites making this one of the most relevant and credible small spacecraft cost models available.

The Small Satellite Cost Model (SSCM) is best suited to the early, conceptual development phase of a spacecraft program when cost and performance trades can be easily performed. A collection of cost-estimating relationships is included that estimate the costs of developing and producing a spacecraft system with the following subsystems:

  • Attitude determination and control subsystem (ADCS)
  • Propulsion
  • Power
  • Telemetry, tracking, and command
  • Command and data handling (C&DH)
  • Structure
  • Thermal

The latest version, SSCM14 (released January 2015), estimates the development and production costs of a small satellite bus for Earth-orbiting or near-planetary spacecraft. The model is based on an underlying database of actual, as-flown technical and cost data provided by spacecraft bus manufacturers.

SSCM14 Features

  • Runs in Microsoft Excel on either PC or Mac; no additional hardware or software capability is required
  • Subsystem-level cost estimation and reporting
  • Non-recurring and recurring subsystem estimate splits
  • Suitable for detailed spacecraft bus and subsystem estimate
  • Earth-orbiting and planetary spacecraft estimating capability
  • Cost-risk analysis
  • Funding profile analysis
  • User-defined inflation factors
  • Notification when cost inputs are out of range
  • Straightforward interface with spreadsheet-based design tools
  • Easy-to-use graphical user interface
  • Save and load multiple data files or cases

SSCM14 is available to organizations in the U.S. and abroad, subject to review by the Aerospace Export Control Office.
