GRACE KBR
SENSOR
Name: GRACE K-Band Ranging System (GRACE KBR)
Swath Width: -1 km
Description: This instrument precisely measures the changes in the separation between the two GRACE satellites using phase tracking of K- and Ka-band signals sent between the two satellites

GRACE ACC
SENSOR
Name: GRACE SuperSTAR Accelerometer (GRACE ACC)
Swath Width: -1 km
Description: The accelerometer, located at the center of mass of each satellite, measures all non-gravitational forces acting on each satellite. These forces include air drag, solar radiation pressure, and attitude control activator operation.
