Detailed description

Inertíuhreyfingastöðin SBG Ellipse A Marine AHRS er þétt og hraðföst stefnu- og stöðumatstöð (AHRS) sem hönnuð er fyrir nákvæma áttavita og bylgjuhreyfingar í erfiðum sjávarumhverfi. Hún notar iðnaðargæða MEMS-ímerihreyfingaröð (IMU) og kalíbreraða segulmæla til að veita áreiðanleg gögn fyrir kröfuhörð notkun eins og kafbátanotkun, stöðugun á tækjum og hreyfingaröðun á yfirborði.

Tækniprestanda og nákvæmni

Ellipse A veitir framúrskarandi nákvæmni í áttavita með 0,1° skekkju í rúllun og stöðuhalli í kyrrstöðu og 0,4° í sjávarhreyfingum. Segulstefna er veitt með 0,8° nákvæmni í kyrrstöðu eftir kalíbrun, fyrir einsleitt segulsvið. Nýjasta kynslóð bylgjuhreyfingaralgrím stillir sjálfkrafa bylgjutímabilið (upp í 15–20 sekúndur), með nákvæmni upp á 5 cm eða 5% (hærra gildið tekið), sem er nauðsynlegt fyrir botnvörpumælingar og stöðugleika í stýrikerfum.

Innbyggðir nemar eru með hröðunarvísa (sjávarviðskiptasvið ±8 g), hringrásanema (±450 °/s) og segulmæla (50 Gauss svið). Þessir nemar eru tengdir við flókin síur til að takast á við titring (8 g RMS við 20 Hz til 2 kHz samkvæmt MIL-STD 810G) og flókin segulkalíbrun til að auka þol gegn tímabundnum segultruflunum. Úttakstíðni IMU-gagna getur náð 1 kHz, sem tryggir skilvirka viðbrögð fyrir stöðugunar- og stefnukerfi.

« Technical evaluation of the SBG Ellipse A Marine inertial measurement unit »

The SBG Ellipse A Marine AHRS inertial measurement unit is a technical solution of choice for marine applications requiring precise attitude and heave determination. Its compact design (46 x 45 x 24 mm, 45 g) facilitates integration in confined spaces, a major advantage for vessels of all sizes. Its robustness is a key strength: the IP68 housing ensures waterproofing against harsh marine environments, while compliance with MIL-STD 810G vibration tests (8 g RMS) and shock tests (500 g) guarantees operational reliability even under extreme conditions. The Ellipse A's ability to provide heave data with 5 cm accuracy, automatically adjusted to wave period, is critical for dynamic positioning systems, bathymetric surveys, or equipment stabilization. The integration of magnetometers with advanced calibration offers valuable redundancy for magnetic heading, particularly useful in case of GNSS failure or unavailability. Multiple interfaces (RS-232, RS-422, USB, CAN) and NMEA compatibility simplify integration with most existing navigation systems. The sbgCenter software streamlines configuration and monitoring, making the device accessible to integrators. With an MTBF of 218,000 hours and factory calibration over a wide temperature range (-40 to 85 °C), long-term durability is ensured.

Frequently asked questions

Need help? Contact us

What is the SBG Ellipse A Marine AHRS inertial measurement unit and what is it used for?

The SBG Ellipse A Marine AHRS (Attitude and Heading Reference System) inertial measurement unit is a compact and rugged sensor designed for marine applications. It integrates an Inertial Measurement Unit (IMU) and magnetometers to provide reliable orientation data (roll, pitch, heading) and heave in dynamic environments, even in the presence of transient magnetic disturbances.

What is the accuracy of the roll, pitch, heading, and heave measurements of the Ellipse A Marine?

The Ellipse A Marine IMU provides high-accuracy measurements:

Roll / Pitch: 0.1° (static)Heading (magnetic): 0.8° (under homogeneous magnetic field after calibration)Heave: 5 cm or 5% (whichever is greater), with automatic wave period adjustment (up to 20 seconds).

Is the Ellipse A Marine IMU waterproof and shock-resistant for marine use?

Yes, the Ellipse A Marine IMU in its housing version is designed for robustness and resistance to marine environments. It is IP68 certified, ensuring resistance to dust and immersion in water (1 hour at 2 meters). Additionally, it meets MIL-STD 810G vibration standards (8 g RMS from 20 Hz to 2 kHz) and shock resistance (500 g for 0.1 ms), ensuring operational reliability even in extreme conditions.

What are the power supply requirements for the Ellipse A Marine inertial navigation unit?
