The First SEER Model Dedicated to a Single Domain:
A Panoramic View of Automated Spacecraft Flight Projects
SEER® for Space is the latest addition to Galorath’s suite of SEER cost estimation models. As the name implies, SEER-Space focuses exclusively on the space domain and produces a more high-level estimate than more granular, component-level models such as SEER for Hardware (SEER-H), to which it is the perfect complement. SEER-Space covers key instruments and spacecraft subsystems and estimates the entire lifecycle cost.
ESTIMATES BASED UPON CREDIBLE, DEFENDABLE DATA SOURCES
SEER-Space is based on a comprehensive variety of recent missions drawn from the NASA CADRe database as well as additional data sources and extensive research by Galorath subject matter experts. It allows early estimation of space missions when little information is known (prephase A, before DoD Milestone A), and may be used during later phases equally well. The model is built on the latest statistical methods including cross-validation to avoid overfitting to the sample data and provide confidence that the Cost Estimating Relationships (CERs) will generalize well when used for prediction. SEER-Space covers all elements of NASA and DoD Work Breakdown Structures, employing a standard Knowledge base template structure that provides a more efficient default starting point for estimating most instrument and spacecraft buses.
BROAD APPLICABILITY TO SPACE MISSIONS
SEER for Space is able to model NASA Class A, B, C and D standards, and examines the effect of Technical Readiniess Level 4-6 additional efforts, if needed. It looks at both Earth and Deep Space missions, from earth orbital missions including Lunar and Lagrange destinations to various Planetary destinations, and can consider numerous types of spacecraft such as Orbiters, Flybys, Landers, and Rovers. SEER-Space can model over 15 different payload instruments such as spectrometers, imaging instruments and more. Also considered are special elements for telescopes and cryocoolers. Instrument Processing Electronics is modeled separately, to allow for better tradeoff of instrument suites as necessary.
MODELS 35 UNIQUE INSTRUMENT TYPES
Comprises all standard instrument types plus recent advanced applications:
- Radars, including Synthetic Aperture
- Lasers, including Optical Transceivers and LIDARS
- Special elements for telescopes and
Instrument Processing Electronics is modeled separately, to allow for better tradeoff of instrument suites as necessary.
MODEL COMPLEX SPACE MISSION CONSTRUCTS
SEER-Space is unique in its ability to estimate instrument suites as well as spares. The model allows for the introduction of contributions into a mission (from part level to whole instruments), and supports the analysis of different procurement methods such as competed versus directed projects, prime contractor versus university-built, foreign contributions, and other situations. It can also assess heritage benefits (mod major, mod minor).
