Detailed description

Inercijalna jedinica SBG Ellipse A Marine AHRS je kompaktni i robusni sustav za određivanje kursa, nagiba i valjanja (AHRS) namijenjen preciznom određivanju orijentacije i valjanja u dinamičkim morskim okruženjima. Integrirana jedinica inercijalnog mjerenja (IMU) zasnovana na tehnologiji MEMS industrijske kvalitete i kalibrirani magnetometri omogućavaju pouzdane podatke za zahtjevne primjene kao što su podvodna navigacija, stabilizacija opreme i praćenje kretanja na površini.

Tehničke performanse i preciznost

Ellipse A nudi izvanrednu preciznost orijentacije s pogreškom od 0,1° u nagibu i valjanju u statičkom režimu, te 0,4° u dinamičkom morskom režimu. Magnetski kurs osigurava preciznost od 0,8° u statičkom režimu nakon kalibracije, pod homogenim magnetskim poljem. Algoritam za valjanje nove generacije automatski podešava period valova (do 15-20 sekundi), osiguravajući preciznost od 5 cm ili 5% (uzima se veća vrijednost), što je ključno za batimetrijske preglede i sustave dinamičkog pozicioniranja.

Ugrađeni senzori uključuju akcelerometre (morski raspon ±8 g), žiroskope (morski raspon ±450 °/s) i magnetometre (raspon 50 Gauss). Ovi senzori su povezani s naprednim filterima za učinkovito upravljanje vibracijama (otpornost 8 g RMS od 20 Hz do 2 kHz prema MIL-STD 810G) i sofisticiranom magnetskom kalibracijom za povećanu robusnost u odnosu na prolazne magnetske smetnje. Izlazna stopa podataka IMU može doseći 1 kHz, osiguravajući optimalnu odgovornost za primjene stabilizacije i ciljanja.

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

The SBG Ellipse A Marine AHRS inertial navigation 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 clear 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 in 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) 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 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?
