Inside GNSS, May/June 2008
NovAtel, Inc., and KVH Industries took advantage of the auspicious occasion of the PLANS 2008 conference to launch their separately labeled but common-design versions of a GNSS/fiberoptic gyro (FOG) inertial measurement unit (IMU) sensor.
Designated CNS-5000 in the KVH version and the SPAN-CPT in NovAtel’s, the sensors integrates NovAtel’s OEMV GNSS receiver with KVH fiberoptic gyro and microelectromechanical (MEMS) accelerometer inertial components. The tight coupling of the GPS and INS technologies within sensors is designed to optimize the raw GPS and IMU data, delivering a 100 Hz 3-D position, velocity and attitude solution.
Comprised entirely of commercial components, GNSS-FOG/IMU sensor has no special export restrictions, according to the companies, minimizing the operational complexities for customers whose products cross international boundaries. Production versions of the new products will be available at the end of July, NovAtel and KVH representatives said.
Based in Middletown, Rhode Island, KVH Industries offers an extensive product portfolio of digital compass and fiberoptic–based products for navigation and positioning. NovAtel, with headquarters in Calgary, Alberta, Canada, is a well-known provider of high-precision GNSS technologies. Their collaboration on the new sensors began last summer.
Additional details on the product can be found in a jointly authored paper, “Performance of a Deeply Coupled Commercial Grade GPS/INS System,” available on the KVH website at <http://www.kvh.com/whitepapers>.
PLANS is itself the product of a cooperative effort between the IEEE Aerospace and Electronics Systems Society and the Institute of Navigation, which brings together the streams of inertial and GNSS navigation technologies for which the two organizations are respectively known.
