MHD Angular Rate SensorsPrecision Sensing, Measurement and Controls

ATA is the industry leader in the design of rugged, precision angular rate sensors. Used for everything from crash and ejection testing, to precision platform stabilization and line-of-sight imaging, our sensors are available in both commercial and space-qualified versions.

Since 1984, our reputation has been built by providing our customers with the finest angular rate sensors available as well as providing applications and long-term customer support. ATA’s designs have proven superior on the ground, in the air, and in extended space flight. We combine our patented ma gneto-hydrodynamic technology with the finest machined components, rugged microelectronics, durable plastics, and encapsulating resins to make sensors that survive the harshest environments. Each sensor is dynamically tested and calibrated to exacting standards.

ATA’s Angular Rate Sensors are based on the principles of magneto-hydrodynamics (MHD). ATA’s patented products exhibit a number of unique beneficial characteristics including:

• A dynamic range exceeding 100 dB • Low noise floor less than 40 nanoradians • Broad bandwidth from ~1 to >1000 Hz • No moving parts for reliability and ruggedness • Very low cross-axis sensitivity • Low linear acceleration sensitivity • Integral electronics for maximum signal-to-noise ratio

Magneto-Hydrodynamic (MHD)Angular Rate Sensor (ARS)

What is an Angular Rate Sensor (ARS)?

Ÿ ATA’s MHD ARS precisely sense and measure jitter disturbances (e.g., base motion jitter) to the nano-radian (nrad) level

Ÿ Nano-radians are very small angles, for example: 1 nrad is about the diameter of a dart board from Albuquerque, NM to the moon

Calibration Services

Every ATA sensor undergoes precise calibration and testing at the time of manufacture. Performance parameters typically do not change significantly with time and use. However, we recommend re-calibration every 12 months.

We also calibrate other manufacturers sensors and accelerometers on a custom order basis. Calibration of angular motion and vibration sensors from DC to 2,000 Hz can be performed using our dynamic calibration systems, and our shock testing can evaluate impacts from 50g to 2,000g. We can supply rate sensors and accelerometers on a custom order basis for distributors and customers.

The ARS-14 is our most sensitive angular rate sensor. It is designed to work in a variety of high-performance applications, such as line-of-sight stabilization and precision motion control systems. The ARS-14 can measure angular motions less than 40 nanoradians, and has low sensitivity to linear acceleration inputs, making it ideal for use in highly dynamic environments such as aerial and ground-based vehicles.

The ARS-15 is our newest angular rate sensor designed to fill the gap between the ARS-06 and the ARS-14. With a noise floor of less than 1.0 microradian, small case size, and low sensitivity to linear inputs, the ARS-15 is ideal for low power airborne applications. The ARS-15 is suitable for accurate, compact systems for line-of-sight pointing and stabilization as well as motion control.

The ARS-06 is a popular addition to our lineup of angular rate sensors. The ARS-06 is available in two standard models: the ARS-06 and the ARS-06S. The ARS-06S uses a single-sided power supply commonly used in automotive crash testing.

The triaxial kit includes three ARS-06 or ARS-06S sensors, three CA-06 cable assemblies, and a triaxial mounting block, which becomes a 6 degree-of-freedom (DOF) measurement system with 3 optional linear accelerometers added to its mounting surfaces. The ARS-06S uses a single-sided power supply commonly used in automotive crash testing.

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 14s exhibit noise equivalent angles (NEAs) of less than 40 nanoradians rms over a 2-1000 Hz integration bandwidth and can incorporate selectable high and low ranges to provide a large dynamic range of jitter measurement.

A custom precision accelerometer package measures low linear acceleration on satellites or other precision platforms. The package provides simultaneous acceleration signals along three orthogonal axes with a commandable dual range of +/- 25mG and +/-1000mG over a 16Hz bandwidth. Two independent sensor sets (dual redundant) are provided in a single enclosure. Separate connectors are used for power and signal connections.
