Low Weight Small Size MEMS Based Dead Reckoning System

iSULONA is a leading solution of INS/GNSS systems, with integrated high performance MEMS IMU  with excellent SWAP. iMAR provides a large amount of versions of iSULONA, depending on the customer's requirements regarding accuracy, vibration and shock hardening and cost.

Dead Reckoning is the way to make GNSS more accurate and reliable when tracking or steering vehicles or when surveying their trajectories, e.g. in defense applications. iSULONA is a hybrid INS/GNSS system, complemented by vehicle motion sensor input. It provides reliable information of position and heading also during GNSS outages in GNSS denied environment.

Furthermore, a specific algorithm designed for land vehicle applications allows an excellend position accuracy in a GNSS denied environment even if no wheel sensor (VMS) is installed. 

For over 30 years, we have been experts in custom, COTS and MOTS inertial measurement systems.

Features

• Used to provide orientation & position of support, supply and logistics vehicles
• Robust, compact, light, minimum SWAP
• robust MEMS gyro technology
• Data output rate up to 500 Hz (each data log separately adjustable)
• Interfaces: UART RS232 & RS422 / CAN / Ethernet / USB for real-time data output and
  for DGPS correction input; NMEA 0183 / iXCOM
• Integrated all-frequencies / all-constellations GPS+GALILEO+GLONASS+Beidou + SBAS + QZSS  GNSS engine, Inteface to military GNSS receivers like ERGR, NavHub, TopStar / SAASM, M-Code
• Dual-antenna GNSS true heading capability integrated (-D)
• integrated all-frequencies / all-constellations GNSS receiver
• designed to work also in GNSS denied environment, under spoofing and jamming conditions
• Interface to vehicle motion sensor (VMS) for full dead reckoning support; the integrated algorithm supports operation on land vehicles with and without vehicle motion sensor, as well as naval applications, airborne applications and missile applications. 
• Powefull software iXCOM-CMD for operation and configuration (under MS Windows, Linux and MacOS) -- see iXCOM-CMD Software
• Inertial System and Sensor Performance:  see datasheets

• Integrated 42+ state sensor data fusion by advanced extended Kalman filtering
• Internally up to 128 GByte non-volatile memory for data storage ("black-box")
• Connectors: MIL-C-38999 III type and TNC / M12
• Power Supply: 10...34 V DC, 10 W. iSULONA provides two independent and isolated inputs to allow the supply from two different power sources - the iSULONAS always takes the energy from those supply with the highest voltage. The inputs are protecxted against reverse voltage and over-voltage.
• Weight: approx. 900 grams, small SWaP
• EMI-EMC protection designed to meet MIL-STD-704F / MIL-STD-461G / MIL-STD-810G; designed partially to meet DO160G
• Modular System architecture: also customized applications can be integrated by iMAR easily (please contact our sales for details). So the iSULONA can provide arbitrary data and command protocols according to customer requirement, e.g. to substitute other navigation systems by iSULONA (e.g. for Form-Fit-Function replacements)
• used in the German Army and other Armed Forces
• iSULONA is neither ITAR nor export controlled.

Note:

In compliance with our proven design philosophy and our technical code of conduct for development, production, and quality assurance of our products and solutions, only physics determines the behavior of iMAR’s measurement systems. The real-time output of our systems and solutions in the inertial signal path is achieved through the intelligent signal processing developed by our experienced engineers – not by artificial intelligence (AI).

Why?

We cannot recommend that integrators or users entrust the success of critical or general missions in inertial navigation, stabilization or control to the heuristic decisions of AI.

Rely on the high reliability, accuracy, and availability of iMAR solutions, as well as on the leading INS/GNSS/+ expertise and experience of our engineering team in Germany. This is based on our mathematically and physically precise algorithms, traceable results, our sensor, hardware, and algorithm design, and our production facilities, which are certified to military and aviation standards.

Note: We apply AI methods in signal processing where they provide benefits for the application (e.g., for improving image or scenario analysis). However, our highest priority is mission safety – even in so-called corner cases of applications, where AI is typically not sufficiently trained.

Several classes of iSULONA are available (all with dual- and single-antenna GNSS available):
