Sada SBG Ellipse D

The SBG Ellipse-D kit includes the following components:

An SBG Ellipse-D Marine inertial navigation system (INS).A triple-band SBG Ellipse-D GNSS antenna.A PSM SMA to TNC LMR240 adapter cable.

The SBG Ellipse D kit provides horizontal RTK positioning accuracy of 0.01 meters. For roll/pitch in RTK, accuracy is 0.05°, and for heading in RTK, it is 0.2°.

Yes, the SBG Ellipse-D kit is designed for demanding marine environments. The Ellipse-D boxed version is IP68 certified, making it resistant to dust and water. It also includes an auto-adjusting heave function, with a precision of 5 cm or 5% (whichever is greater) for wave periods of 0 to 20 seconds.

The SBG Ellipse D supports multiple GNSS constellations on the L1 and L2 frequency bands. It is compatible with:

GPS: L1C/A, L2C
GALILEO: E1, E5b
GLONASS: L1OF, L2OF
BEIDOU: B1/B2
It also supports QZSS and SBAS.

The SBG Ellipse D can be integrated with various external sensors to enhance its accuracy and robustness, including:

Wheel sensors. DVL (Doppler Velocity Log). External magnetometers. Aeronautical data sensors (Air data). These sensors improve positioning accuracy, particularly during GNSS outages.

The SBG Ellipse D offers multiple communication interfaces to facilitate its integration:

Serial interfaces: RS-232 and RS-422 (up to 2 Mbps). USB: For connection and configuration. CAN: CAN 2.0 A/B (up to 1 Mbps). Sync I/O: Two sync inputs (RS232) and one sync output (TTL).

Yes, the SBG Ellipse D kit is compatible with several software solutions and platforms:

Qinertia: SBG Systems' proprietary post-processing software, which enhances performance by processing raw inertial data and GNSS observables. ROS (Robot Operating System): A ROS driver is available for full compatibility. Pixhawk: An open-source hardware platform for autopilot systems. It is also compatible with GNSS receiver input protocols from brands such as Novatel, Septentrio, and u-blox.

The SBG Ellipse D kit comes with a 2-year warranty.

The SBG Ellipse D housing has compact dimensions of 46 mm x 45 mm x 32 mm. Its weight is 65 grams.

The SBG Ellipse D housing is rated with an IP68 protection index. This means it is resistant to dust and water, making it suitable for marine and demanding environments.

The SBG Ellipse D integrates an advanced sensor fusion algorithm that combines inertial measurement unit (IMU) data with GNSS information and external sensor inputs (such as an odometer or DVL). This fusion ensures precise and robust positioning, even when GNSS signals are temporarily unavailable, for example under bridges or in forested areas.

The SBG Ellipse D operates with an input voltage of 5 to 36 VDC. Its power consumption is less than 1050 mW.

Yes, the SBG Ellipse D provides real-time wave data. It offers an accuracy of 5 cm or 5% (whichever is greater) for wave periods ranging from 0 to 20 seconds, with automatic adjustment.

The main difference lies in heading capability. The Ellipse-D features a dual GNSS antenna, enabling it to provide precise and stable heading even in static conditions. The Ellipse-N, on the other hand, lacks this dual-antenna heading functionality.

The SBG Ellipse D is designed to operate in demanding environments and meets the MIL-STD-810G standard. It can withstand:

Operating temperatures from -40 °C to 85 °C.Vibrations up to 8 g RMS (from 20 Hz to 2 kHz).Shocks up to 500 g for 0.1 ms.Its housing is also rated IP68, making it resistant to dust and water.
