QRS-11—Quartz Rate Sensor

The QRS-11 GyroChip sensor is used on commercial aircraft to rotate the antenna to receive signals from satellites for the in-flight entertainment system, radar tracking and flight controls. If the aircraft is equipped with an uninterruptable autopilot, signals can be received from a satellite to remotely fly the aircraft.

The sensor provides stabilization, flight control, and guidance. It also is used in missiles, Unmanned Aerial Vehicles (UAV ) and other military as well as space and industrial applications. Because of the sensitive nature of its military applicatons, the export of the technology is regulated.


We allege that the QRS-11 can be used as part of a package of technology to guide aircraft equipped with uninterruptable autopilots turning them into weapons.

We believe that the patent for the device was originally obtained by the Rose Law Firm of Little Rock, AR, specifically by patent lawyer Hillary Clinton, for BEI Technologies, Inc. headquartered at that time in Arkansas.

BEI has deversifed many times since then and the QRS-11 is now Manufactured by CST Systron Donner Inertial.

QRS11 High Performance (Military Grade) Rate Sensor

The QRS11 is a compact, lightweight design, that features Quartz MEMS technology providing a solid-state gyro offering virtually unlimited life. The QRS11’s combination of high performance and long life makes it well suited for OEM’s and system integrators designing cost effective, high performance systems.

The QRS11 requires only DC voltage inputs to provide reliable, extremely accurate angular rate measurements with the benefit of no moving parts. With a hermetically sealed sensing element, the QRS11 has provided reliable performance in aircraft, missile and space systems across many demanding application environments.
