The smallest and lightest of NovAtel's SPAN® products, the SPAN-IGM series of Micro Electromechanical Systems (MEMS) inertial sensor products provides two options for developers looking to integrate a high precision positioning system, capable of continuous navigation in difficult or GNSS-denied environments.
The SPAN-IGM Series includes the IMU-IGM-A1 MEMS enclosure and the SPAN-IGM-A1 GNSS + INS enclosure. By leveraging our powerful SPAN technology, both of these products are ideal for applications that are size and weight constrained but still require highly precise position, velocity, roll, pitch and heading.
The IMU-IGM-A1 enclosure houses a small MEMS inertial sensor. The IMU-IGM-A1 can be configured from the factory as an integrated GPS/GNSS Inertial Navigation System (INS) or as a standalone IMU sensor for pairing with a customer's existing NovAtel SPAN enabled OEM6 receiver.
The SPAN-IGM-A1 enclosure combines NovAtel's OEM615 GNSS receiver card with a MEMS inertial sensor in the same unit. By integrating the MEMS IMU with NovAtel's industry leading OEM6 GNSS/INS SPAN engine, advanced positioning options such as AdVance® RTK, ALIGN® heading technology and RAIM are available to maximize performance.
