New IMU offers Drift-Free Orientation and Position Data for Indoor Navigation and Tracking


ByDinesh Kumar 0


ROMOS is the patented RealMotion Technology that unlike the existing IMUs ensures to deliver DRIFT-FREE orientation and position data to connected components such as microcontrollers and microprocessors. In simple words, ROMOS is a self-tracking (inside-out) IMU that does not require an external signal to track an object's movements. It can track your path even when the GPS signal is weak or fails underground, in buildings, or tunnels and it doesn’t require additional external reference signal (s) to compensate for drift error.

Packed with out-of-the-box features like communications and electrical compatibility with conventional IMUs minimizing design-time for Engineers, ROMOs is the best bet. Perfect 3D orientation, Drift-free 3d position tracking, sub-millimeter variance, standard communications, compact form factor, flexible configuration are its added features. With ROMOS, it becomes easier for users to use their Augmented or Virtual Reality Headset without being confined to space or a room as it delivers true motion without boundaries. The position data in ROMOS is generated at a high rate through internal MEMS-based inertial sensors for direct use in the host application.

ROMOS is designed with minimal real-estate per package type with a range of compact form factors to suit all applications. Along with it, the modularity is kept in mind while designing ROMOS and protocols as well as IOs can be customized to meet new specifications for fast design-to-production time. Its orientation is established via complex computations in multidimensional vector-space and projected on to 3D Euclidean space. Using higher dimensional computations with back-propagation, drift is eliminated from positional data.

Once the users initialize ROMOS, it experiences a maximum of 0.5mm static variance offset from true position data over its operational lifetime. Besides, ROMOS employs fast-mode SPI, I2C, or UART signals for immediate communication compatibility with existing boards and architecture. Long-term sustained location tracking enabled by ROMOS, in the absence of GPS or other external reference systems, unveils new dimensions and solutions for a wide range of applications.

From opening the possibility of circumnavigating the globe without GPS, creating the World's first Terrestrial Positioning System (TPS) to help autonomous vehicles gain low-latency and high-accuracy positioning, robotics, enabling consumers to move freely with accurate location tracking apps, offering low-cost redundant position-estimation module for transponders on Airplanes, Drones, or UAVs, ROMOS finds its applications in various areas. Not just that, aerospace (precise orbital tracking), first responders (accurately tracking 3D movements of first-responders within buildings and elevations) and family care (keeping you informed of your dependents’ exact whereabouts for safety) are the other application areas of ROMOS.
