iMAR has launched the first systems for train applications, where the integration of a robust INS/GNSS/ODO solution together with radio communication is proivded within one enclosure. It provides GSM-R, LTE and as an option 5G communication. The system is designed according to the common railway vehicle standards regarding environmental impacts, EMI/EMC and power supply.

iRailLoc-C is based on iMAR's well-known iNAT system architecture, used in airborne, shipborne and land navigation applications. It has its roots on its famous predecessor iDRPOS / iRailLoc-A, iMAR's dead-reckoning based railway localization system from 2004. iMAR's inertial measurement systems are used on many rail surveying trains and challenging surveying tasks in Europe and worldwide since decades as well as for fleet localization, navigation and control. The range of iMAR solutions for localization, navigation, communication, guidance, surveying and control ranges from highest acuracy to most economic solutions.
