Miniature Inertial Navigation Systems | Micro INS for UAV, UGV

Custom miniature inertial navigation sensors (INS) are compact, low-power MEMS-based devices that integrate gyroscopes, accelerometers, magnetometers, and GNSS receivers to provide precise position, velocity, and orientation for space-constrained platforms like UAVs, robotics, and drones . These systems, such as the SBG Systems Ellipse series and Inertial Labs KERNEL-201, are designed for high-performance, GNSS-denied navigation, offering features like RTK positioning and ruggedized casings.

This video demonstrates how to assemble and test a custom navigation sensor PCB:

Key Types and Features

MEMS-Based INS: Uses micro-electro-mechanical systems for high-performance navigation, including gyros, accelerometers, and magnetometers.
GNSS-Aided INS: Combines internal or external GNSS receivers with inertial sensors for accurate, real-time position data, such as the Ellipse-D or VN-200 .
Ruggedized Modules: Designed to withstand harsh environments with IP-rated protection, meeting standards like MIL-STD-810.
High-End Accuracy: Offers low-drift, high-bandwidth data, such as the Kernel-201 's high dynamic range or Ellipse-E 's 0.05° roll/pitch accuracy.

Applications

Unmanned Systems: UAVs, UGVs, and AUVs requiring small form factors (SWaP).
Navigation & Guidance: Autonomous vehicle navigation and pointing/stabilization systems.
Mapping & Surveying: Remote sensing payloads, such as the RESEPI system , for aerial mapping.
