Angular  vibration (jitter) degrades the quality of imagery collected by satellites. The Dynapak 12 triaxial  sensor packages measure ultra-low level angular jitter on precision  imaging  satellites  in the sub-microradian regime.  All  Dynapak 12's exhibit noise equivalent angles (NEAs) of less  than 50 nanoradians  rms  over  a 2-1000 Hz integration bandwidth and incorporate spacecraft selectable high and low  ranges  to  provide a  large dynamic range of jitter measurement on the spacecraft.

The Dynapak 12 sensor packages were designed to measure angular jitter on satellites, but can be used anywhere angular jitter must be monitored. The sensor  packages  use  three  space qualified ATA ARS-12B sensors with the option of a DC-DC converter for running the sensor package directly from the spacecraft bus.  The outputs are bipolar analog signals (one per axis) along with a temperature telemetry output. 

The three-axis jitter measurements may be used as a diagnostic tool to optimize the performance of the spacecraft, or other platform.  Jitter measurements recorded simultaneously with digital image data can be used to enhance images during post-processing.

Dynapak 12 outputs are typically in angular rate, but may also be conditioned to provide angular  displacement  or acceleration.
 

ATA Sensors can provide custom designed space-qualified, triaxial jitter  measurement packages with  various  bandwidths  and scale factors. Dual-range selection as well as other output  options (current or frequency proportional to angular rate, displacement or acceleration) are also available.  ATA Sensors has the expertise to assist in selecting the right set of options for the intended application.
