Introducing the Ellipse-N: A Compact High-Performance RTK Inertial Navigation System
The Ellipse-N is a compact, high-efficiency RTK Inertial Navigation System (INS) that comes equipped with an integrated GNSS receiver. It delivers precise data on Roll, Pitch, Heading, Heave, and Navigation.
Advanced sensor technology
This lightweight device features a MEMS-based Inertial Measurement Unit (IMU) that incorporates three gyroscopes, three accelerometers, and three magnetometers. Additionally, it includes a dual-frequency RTK and a quad-constellation GNSS receiver. The Ellipse-N utilizes an advanced Extended Kalman Filter (EKF) to seamlessly combine inertial data with GNSS signals, odometer inputs, and RTK corrections, ensuring superior orientation and navigation capabilities even in the most demanding conditions.
Precision Metrics
- Roll and Pitch accuracy of 0.05° across a full 360° (RTK)
- Heading accuracy of 0.2° (RTK under high dynamics)
- Real-time Heave accuracy of 5 cm, fine-tuned to wave periods
- GNSS Position accuracy of 1 cm
Notable Features
- Extremely Low Noise gyroscopes
- 64-bit architecture for advanced filtering capabilities
- Compatible with GPS, GLONASS, BEIDOU, and GALILEO systems
- Supports Differential Corrections
- Post-processing capabilities available
- Integration with Odometer systems
- Output rate of 200 Hz
The Ellipse-N’s accuracy and features are housed in a robust IP68-rated enclosure or can be provided in a lightweight 17-gram OEM PCB-mounted version. It also comes with a two-year warranty for added peace of mind.
