Based on hemispherical resonator gyro technology

The Hemispherical Resonator Gyroscope is a high performance angular rate or rotation sensor. The Anschütz Standard 30 MF Gyro Compass is a maintenance free gyro compasses based on this hemispherical resonator gyro (HRGs) technology.
The use of HRG technology together with the simple design makes it extremely reliable with no wear and tear and no need for maintenance.

Mean time between failures

The mean time between failures (MTBF) value is more than 100,000 hours which is a multiple of the MTBF values of optical gyros (such as FOGs). The Standard 30 MF can be used as rate-of-turn indicator (required for vessels above 50.000 GT according to SOLAS) and features an optimized integration into a Raytheon Anschütz heading management system.

Longterm stability

Developed with a strong focus on robustness, Standard 30 MF settles even at rough sea states and provides heading output even if speed and latitude input fails – a significant advantage over other compass systems.

Unsurpassed lifetime performance

HRGs are vibrating resonator gyros consistingof only a few elementary pieces, assembled in a miniature hemisphere decoupled from the outside equipment: A single resonator and electronics for resonator control and vibration sensing. The simple design was engineered to make the gyro extremely reliable with no wear and tear and no need for maintenance.


Highest operational safety under harshest environmental conditions.
High accuracy of 0.25 degrees, ultra-robust design
Highly cost-effective over lifetime through maintenance-free technology
Superior and durable HRG technology (MTBF >100,000 h)
Heading sensor and MRU in one (roll and pitch output), thus reduction in investment and maintenance cost
Settling time of only one hour, settles at rough sea states Heading monitor and selector with automatic switch-over (configurable)
Automatic speed / latitude error correction
Individual speed error correction

Standard 30 MF interfaces

A modular product range enables different system configurations – from a single compass up to a multi compass system consisting of magnetic compass, Standard 22, Standard 30 MF and redundancy in distribution.
The integration into the heading management system is realized through redundant CAN interfaces. The CAN bus reduces the wiring effort between the components to a minimum, over a distance of up to 400 meters with real-time communication.
