The STIM300 is a Micro Electromechanical System (MEMS) Inertial Measurement Unit (IMU) from Sensonor. It features low noise gyros and accelerometers in a small, lightweight, environmentally sealed enclosure. The STIM300 enables precision measurements for applications that require low cost, high performance and rugged durability in a very small form factor. When integrated with NovAtel's Synchronous Position, Attitude and Navigation (SPAN) technology, this IMU is ideal for airborne and ground applications that require accurate 3D position, velocity and attitude (roll, pitch and azimuth) data.

About SPAN: Tightly-Coupled GNSS +INS Technology
SPAN technology brings together two different but complementary technologies: Global Navigation Satellite System (GNSS) positioning and Inertial Navigation Systems (INS). The absolute accuracy of GNSS positioning and the stability of IMU measurements combine to provide an exceptional 3D navigation and attitude solution that is stable and continuously available, even through periods when satellite signals are blocked.
Combining SPAN and MEMS Technology
A proprietary NovAtel MEMS Interface Card (MIC) couples the STIM300 with SPAN receiver cards, offering a unique, powerful GNSS+INS system for weight and size constrained applications. Designed as a board stack configuration for ease of integration, the MIC interfaces directly with NovAtel's small form factor OEM615™ SPAN receiver.
