Detailed description

La centrala inercial SBG Ellipse A Marine AHRS és un sistema de referència d'actitud i de rumb (AHRS) compacte i robusta, dissenyat per a la determinació precisa de l'orientació i el balanceig en entorns marins dinàmics. Integrant una unitat de mesura inercial (IMU) basada en la tecnologia MEMS de qualitat industrial i magnetòmetres calibrats, proporciona dades fiables per a aplicacions exigents com la navegació submarina, l'estabilització d'equips i el seguiment de moviments en superfície.

Prestacions tècniques i precisió

L'Ellipse A ofereix una precisió d'actitud remarcable amb un error de 0,1° en balanceig i cabussament en mode estàtic, i de 0,4° en dinàmic marí. El rumb magnètic es proporciona amb una precisió de 0,8° en estàtic després de la calibració, sota un camp magnètic homogeni. Un algoritme de balanceig d'última generació ajusta automàticament el període de les ones (fins a 15-20 segons), garantint una precisió de 5 cm o 5% (el valor més alt), essencial per a les prospeccions batimètriques i els sistemes de posicionament dinàmic.

Els sensors integrats inclouen acceleròmetres (rang marí de ±8 g), giroscopis (rang marí de ±450 °/s) i magnetòmetres (rang de 50 Gauss). Aquests sensors estan associats a filtres avançats per a una gestió eficient de les vibracions (resistència de 8 g RMS de 20 Hz a 2 kHz segons MIL-STD 810G) i a una calibració magnètica sofisticada per a una major robustesa davant de pertorbacions magnètiques transitòries. La freqüència de sortida de les dades IMU pot assolir 1 kHz, assegurant una reactivitat òptima per a aplicacions d'estabilització i apuntament.

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

The SBG Ellipse A Marine AHRS inertial measurement unit 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 an undeniable 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 crucial 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 an 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 navigation unit and what is it used for?

The SBG Ellipse A Marine AHRS inertial navigation unit (Attitude and Heading Reference System) is a compact and robust 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 roll, pitch, heading, and heave measurements for 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 to be robust and resistant to marine environments. It is IP68 certified, ensuring resistance to dust and immersion in water (1 hour at 2 meters).
