SBG Systems has released the Ellipse Series, a product range of miniature inertial systems replacing the IG-500 Series. For the same budget, customers benefit from higher accuracy, advanced filtering and features of high-end inertial navigation systems, the company said.

The Ellipse Series of miniature inertial systems benefits from a new design, new sensors, new capabilities, and new algorithms. “We have selected state-of-the-art MEMS sensors, especially very low noise gyroscopes that greatly enhance Ellipse performance. We integrated cutting-edge GNSS receiver while keeping a small size,” said Alexis Guinamard, CTO of SBG Systems.

“We are able to upgrade miniature sensors capabilities by injecting some advanced and proven filtering and features inspired from high end inertial navigation systems,” Guinamard said. Besides higher accuracy, SBG Systems added for the same budget an improved FIR and rejection filtering, robust IP68 enclosure, high output rate, RTK corrections, and automatic alignment.

Weighting from 45 grams, Ellipse sensors are flexible. The Ellipse-A model provides 3D orientation and heave. For navigation, users can connect their own GPS receiver with the Ellipse-E, or use an internal receiver by choosing the Ellipse-N model. The larger Ellipse-D integrates a survey-grade L1/L2 GNSS receiver with two antennas for heading and position accuracy.

Ellipse A, N, E models are available for order now. The Ellipse-D model will be available in the first quarter of 2015.
