As a professional MEMS INS GNSS Integrated Navigation Solution, the system incorporates comprehensive full-temperature bias and scale factor compensation for the internal IMU module, ensuring consistent reliability and performance even in extreme temperature environments, from frigid arctic conditions to sweltering industrial settings. It also supports flexible multi-scenario configuration modes to seamlessly adapt to airborne, vehicular, and marine applications. For vehicle-mounted use cases, it specifically integrates vehicle constraint algorithms (such as non-holonomic constraints) to further constrain drift and maintain high-precision attitude measurement over extended periods of GNSS outage.
Advanced Manufacturing and Technology
As a leading MEMS INS GNSS Integrated Navigation Solution, the MNAV-H015 leverages state-of-the-art MEMS manufacturing techniques to integrate high-performance gyroscopes and accelerometers within a miniaturized, rugged structure—capable of directly replacing low-precision fiber optic gyroscope (FOG) modules in many applications at a fraction of the cost and size. These inertial sensors represent the cutting edge of MEMS inertial device technology, offering exceptional stability and sensitivity. The system implements full-temperature compensation for a comprehensive set of error sources, including bias drift, scale factor variation, non-orthogonal alignment errors, and acceleration-induced errors, ensuring long-term measurement precision without frequent recalibration. Additionally, an advanced adaptive attitude algorithm is embedded to dynamically adjust to changing motion profiles, further enhancing the stability and reliability of attitude measurements over time, even under high-vibration or dynamic maneuvering conditions.
Key Technologies: Self-Alignments and More
Backed by a wealth of proprietary core technologies accumulated through years of R&D, this MEMS INS GNSS Integrated Navigation Solution delivers exceptional performance and operational flexibility. Equipped with high-performance MEMS gyroscopes sensitive enough to detect the Earth’s rotation, the MNAV-H015 achieves initial self-north finding without relying on auxiliary heading devices such as dual-antenna GNSS receivers or magnetic compasses. This capability is particularly valuable in environments where magnetic interference is a concern or where dual-antenna setups are impractical. By autonomously determining the true north direction during initialization, the system enables rapid convergence to high-precision navigation solutions during dynamic integrated navigation operations, ensuring continuous, reliable performance even in GNSS-denied or challenging operational scenarios.
