NovAtel SPAN-CPT
SPAN-CPT integrates NovAtel's OEMV GNSS precision receiver technology with fiber optic gyro and MEMS accelerometer inertial components from KVH Industries in one compact unit. The tight-coupling of the GPS and INS technologies within SPAN-CPT optimizes the raw GPS and IMU data, delivering a superior position, velocity and attitude solution. Comprised entirely of commercial components, SPAN-CPT has no special export restrictions, minimizing the operational complexities for customers whose products cross international boundaries.
GNSS + INS with SPAN
NovAtel’s SPAN (Synchronous Position, Attitude and Navigation) technology brings together two different, but complementary technologies: GNSS positioning and inertial navigation. The absolute accuracy of GNSS positioning and the stability of IMU gyro and accelerometer measurements combine to provide a 3D position, velocity and attitude solution. Unlike GNSS-only navigation systems, the solution is stable and continuously available, even through periods when GNSS signals are blocked.
SPAN-CPT Overview
SPAN-CPT is a single-enclosure GPS+INS positioning system, powered by NovAtel’s professional-grade OEMV® GNSS technology. Solution accuracy can be varied by application by enabling different positioning modes including SBAS, L-band (Omnistar and CDGPS) and RTK.
The IMU components are comprised of Fiber Optic Gyros (FOG) and Micro Electrical Mechanical Systems
(MEMS) accelerometers from KVH Industries that offer the best price/performance available. FOGs offer
exceptionally long life and stable performance compared with other gyro technologies.
All of this is combined into one compact, environmentally sealed enclosure for simple installation and easy integration.
SPAN-CPT Advantages
Like all SPAN products, SPAN-CPT tightly couples the GPS and IMU measurements together in order to get the most satellite observations and the most accurate solution possible.
Applications often require operation in multiple countries. SPAN-CPT is
comprised entirely of commercial components, which means that export headaches involved with traditional GPS/INS systems are greatly minimized.
