Detailed description

Inertsiaalse anduri SBG Ellipse A Marine AHRS on kompaktne ja vastupidav hoiakut ja kurssi määrav süsteem (AHRS), mis on välja töötatud mere dünaamilistes tingimustes asendi ja kõikuvuse täpseks määramiseks. See sisaldab tööstusliku kvaliteediga MEMS-tehnoloogiale põhinevat inertsiaalset mõõtühikut (IMU) ja kalibreeritud magnetomeetreid, pakkudes töökindlaid andmeid nõudlikele rakendustele nagu allveelaevandus, seadmete stabiliseerimine ja liikumise jälgimine veepinnal.

Tehnilised näitajad ja täpsus

Ellipse A pakub märkimisväärset hoiakutäpsust: 0,1° veeremise ja tõstmise veasuurus statsionaarses režiimis ning 0,4° dünaamilises mererežiimis. Magnetahel on pärast kalibreerimist 0,8° täpsusega statsionaarses režiimis ühtlase magnetvälja tingimustes. Uusima põlvkonna kõikuvusalgoritm kohandab automaatselt laineperioodi (kuni 15–20 sekundini), tagades 5 cm või 5% täpsuse (sõltuvalt sellest, mis on suurem), mis on oluline batümeetriliste uuringute ja dünaamilise positsioneerimise süsteemide jaoks.

Seadme sensorid sisaldavad aktselereomeetreid (mereskaala ±8 g), güroskoope (mereskaala ±450 °/s) ja magnetomeetreid (50 Gaussi skaala). Need on ühendatud täiustatud filtritega vibratsioonide efektiivseks juhtimiseks (8 g RMS vastupidavus 20 Hz – 2 kHz sagedusvahemikus vastavalt MIL-STD 810G) ja keerukate magnetkalibratsioonidega, et suurendada vastupidavust ajutistele magnethäiretele. IMU andmete väljundikiirus võib ulatuda kuni 1 kHz, tagades optimaalse reageerimiskiiruse stabiliseerimise ja sihtimise rakendusteks.

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

The SBG Ellipse A Marine AHRS inertial measurement unit (IMU) 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) simplifies integration into tight spaces, a major advantage for vessels of all sizes. 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. 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.

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 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 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). 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?
