Description détaillée

Centrala inerțială SBG Ellipse A Marine AHRS este un sistem de referință a atitudinii și a capului (AHRS) compact și robust, proiectat pentru determinarea precisă a orientării și a balansului în medii marine dinamice. Integrează o unitate de măsurare inerțială (IMU) bazată pe tehnologia MEMS de calitate industrială și magnetometre calibrate, furnizând date fiabile pentru aplicații solicitante precum navigația subacvatică, stabilizarea echipamentelor și monitorizarea mișcărilor la suprafață.

Performanțe tehnice și precizie

Ellipse A oferă o precizie remarcabilă a atitudinii, cu o eroare de 0,1° în ruliu și tangaj în mod static, respectiv 0,4° în mod dinamic marin. Capul magnetic este furnizat cu o precizie de 0,8° în static, după calibrare, sub un câmp magnetic omogen. Un algoritm de balans de ultimă generație ajustează automat perioada valurilor (până la 15-20 secunde), garantând o precizie de 5 cm sau 5% (valoarea cea mai mare fiind reținută), esențială pentru ridicările batimetrice și sistemele de poziționare dinamică.

Senzorii integrați includ accelerometre (plajă marină de ±8 g), giroscopi (plajă marină de ±450 °/s) și magnetometre (plajă de 50 Gauss). Acești senzori sunt asociați cu filtre avansate pentru gestionarea eficientă a vibrațiilor (rezistență de 8 g RMS între 20 Hz și 2 kHz conform MIL-STD 810G) și cu o calibrare magnetică sofisticată pentru o robustețe crescută în fața perturbațiilor magnetice tranzitorii. Rata de ieșire a datelor IMU poate atinge 1 kHz, asigurând o reactivitate optimă pentru aplicațiile de stabilizare și punctare.

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

The SBG Ellipse A Marine AHRS inertial measurement unit (IMU) represents 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 into confined spaces, a major asset 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 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 facilitate integration with most existing navigation systems. The sbgCenter software simplifies configuration and monitoring, making the device accessible to integrators. With a MTBF of 218,000 hours and factory calibration over a wide temperature range (-40 to 85 °C), long-term durability is ensured.

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 robust sensor designed for marine applications. It integrates an inertial measurement unit (IMU) and magnetometers to provide reliable data on orientation (roll, pitch, heading) and heave in dynamic environments, even in the presence of transient magnetic disturbances.

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

The Ellipse A Marine IMU provides high accuracy for its 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 adjustment to wave period (up to 20 seconds).

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

Yes, the housing version of the Ellipse A Marine IMU is designed to be robust and resistant to marine environments. It is IP68 certified, ensuring resistance to dust and water immersion (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 measurement unit?

The SBG Ellipse A Marine AHRS inertial measurement unit (IMU) requires a direct current (DC) power supply. The accepted input voltage range is 5 to 36 VDC. Its power consumption is very low, under 300 mW.
