Mass Properties Testing

Pre-launch mass properties testing, including center of mass (CG) and moment of inertia (MOI), is required by launch providers prior to launch vehicle integration. These quantities can also affect the operation of the spacecraft during dispensing, deployment, rotation maneuvers, and translation maneuvers. SDL is experienced in characterizing mass properties for small spacecraft and is capable of mass and CG measurements up to 54 kg and MOI measurements for spacecraft up to 10 kg in our SmallSat Verification & Validation Lab.

Test Capabilities

  • Mass and CG measurement
  • MOI Measurement



Dynamic Ionosphere CubeSat Experiment

Twin CubeSats mapped the geomagnetic Storm Enhanced Density (SED) plasma bulge and plume formations in Earth’s ionosphere.


Auroral Spatial Structures Probe

ASSP was designed to measure the spatial and temporal variation of the energy flow in the upper atmosphere in and around the aurora to better understand global temperature changes in the thermosphere.


Hyper-Angular Rainbow Polarimeter

The HARP instrument is a wide field-of-view hyper-angular imaging polarimeter designed to characterize aerosol and cloud properties.

Spacecraft Platform

SDL’s spacecraft platform is a set of standard and customizable components that can be assembled into multiple mission configurations while minimizing non-recurring engineering costs and development schedules.
