AQUILA

Rad-Hard Space Accelerometer 

AQUILA

 

 

 

 

High-Performance Sensor

AQUILA is a rad-hard Delta Velocity Measurement Accelerometer based on InnaLabs® successful quartz pendulum accelerometer products and heritage. It measures the velocity change and transitions of satellites in orbit. The primary application of AQUILA is navigation and Fault Detection Isolation and Recovery (FDIR) on board satellites as well as for land, marine, and aerospace applications. AQUILA objective is to qualify a space-grade accelerometer that will withstand 30krad.
