SBG Ekinox Micro: Compact INS
The Ekinox Micro compact INS combines a high-performance MEMS inertial sensor with a multi-frequency, dual-antenna GNSS receiver to provide unmatched accuracy, even for the most challenging applications. Designed to operate in the harshest conditions, the Ekinox Micro is military standard compliant, making it the ideal choice for any mission critical application.
Description
Overview
The Ekinox Micro is small and lightweight, yet rugged enough to handle any application. It includes pre-configured motion profiles for land, air, and marine applications, allowing the sensor and algorithms to be tuned for maximum performance in any situation.
One of the features of Ekinox Micro is its dual-antenna GNSS receiver for heading; however, field-proven algorithms also allow maximum performance even in single-antenna mode.
The Ekinox Micro is designed for ease of use and integration, with simple connectors, a web configuration interface, a datalogger, Ethernet connectivity, a PTP server, and a REST API for configuration and multiple input and output formats. This allows developers to easily integrate it into their applications and workflows.
The Ekinox Micro is RTK compatible and based on a tactical 0.8°/h class IMU, calibrated across the entire operating temperature range, with accuracy roll/pitch of 0.015° and accuracy heading of 0.035° and accuracy position of 1.2 m in without any corrections or 1cm in RTK.
The Ekinox Micro also embeds several technologies to fight against GNSS jamming and spoofing. Its dual-band, full-constellation GNSS significantly reduces the chance of an attack being successful. Its mitigation algorithms filter jamming and spoofing, with flags to inform the user whenever corrupted signal is detected.
Furthermore, the Ekinox Micro offers an automatic aggressive regression mode to fall back on inertial sensors and velocity aiding as soon as a potential jamming or spoofing event is detected. This allows the system to be used in hostile environments with great efficiency, and to continue navigating for extended periods of time when combined with velocity aiding such as Odometry, DVL or Airdata.
Features
- Compact Yet Rugged – The Ekinox Micro is small and lightweight, yet tough enough to be used in the toughest environments, with conformance to military standards MIL-STD-461G, MIL-STD-1275E and MIL- STD-810H.
- Optimal Performance Everywhere – The Ekinox Micro includes pre-configured motion profiles for all land, air and sea applications enabling fast tuning of the sensor for optimum performance in every situation.
- Ease of Use & Integration – With Ethernet connectivity and user-friendly connectors and configuration interface, the Ekinox Micro is fully plug and play. Developers can also integrate it using the REST API for configuration, and multiple input/output formats.
- Single/Dual Antenna Heading – The Ekinox Micro can be used in single antenna mode and reach its maximum performance. However, for applications with low dynamics it also operates as a dual antenna GNSS compass.
