Multi-Axis ARS Package (Dynapak)

Designed to measure jitter from airborne mirrors, optical systems or lasers, and for accurate line-of-sight imaging platform stabilization, the Dynapak 14 triaxial sensor packages measure ultra-low level angular jitter in the sub-microradian regime.  All Dynapak 14's  exhibit noise equivalent angles (NEAs) of less than 50 nanoradians rms over a 1-1000 Hz integration bandwidth and can incorporate selectable high and low ranges to provide a large  dynamic range  of jitter measurement. 

The Dynapak 14 sensor packages can be used anywhere angular jitter must be monitored.  The sensor packages use three ARS-14 sensors, and optional power/signal conditioning and temperature measurement electronics. The outputs are bipolar analog signals. 

Dynapak 14 outputs are in angular rate similar to an AC-coupled high-bandwidth gyroscope. ATA can provide custom designed triaxial jitter measurement packages with various bandwidths and scale factors. 

Custom space-qualified 3-axis packages are also available.
