IMU-K VH1750
IMU-KVH1750 WITH NOVATEL’S
GNSS TECHNOLOGY PROVIDES
CONTINUOUS 3D POSITION,
VELOCITY AND ATTITUDE SOLUTION
SPAN: WORLD-LEADING GNSS+INS TECHNOLOGY
Synchronous Position, Attitude and Navigation (SPAN) technology brings together two
dierent but complementary technologies: Global Navigation Satellite System (GNSS)
positioning and inertial navigation. The absolute accuracy of GNSS positioning and the
stability of Inertial Measurement Unit (IMU) gyro and accelerometer measurements
are tightly coupled to provide an exceptional 3D navigation solution that is stable and
continuously available, even through periods when satellite signals are blocked.
IMU-KVH1750 OVERVIEW
The IMU-KVH1750 is designed to be paired with NovAtel’s OEM6® line of receivers.
Commercially exportable, it is comprised of Fiber Optic Gyros (FOG) and Micro
Electromechanical Systems (MEMS) accelerometers. FOGs oer exceptionally long life
and stable performance compared to similar gyro technologies.
ADVANTAGES OF IMU-KVH1750
The IMU-KVH1750 oers tactical grade performance in a compact and rugged
package with minimal power consumption. Paired with NovAtel’s OEM6 receiver, the
IMU-KVH1750 oers a fully integrated, tightly coupled GNSS and IMU system that
delivers a continuous position, velocity and attitude solution.
IMPROVE IMU-KVH1750 ACCURACY
Take advantage of NovAtel CORRECT™ to receive your choice of accuracy and
performance, from decimetre to RTK-level positioning. For more demanding
applications, Inertial Explorer® post-processing soware from our Waypoint®
Products Group can be used to post-process IMU-KVH1750 data to provide the
system’s highest level of accuracy.

1. Typical SPAN system performance values when using this IMU. Performance
specifications subject to GPS system characteristics, US DOD operational
degradation, ionospheric and tropospheric conditions, satellite geometry,
baseline length, multipath eects and the presence of intentional or
unintentional interference.
2. GPS-only.
3. Requires subscription to TerraStar data service. Subscriptions available from
NovAtel.
4. An OEM628, OEM638, FlexPak6 or ProPak6 receiver is required.
5. Time accuracy does not include biases due to RF or antenna delay.
6. Export licensing restricts operation to a maximum of 515 metres/second.
7. Supplied by IMU manufacturer.
8. RMS, incremental error growth from steady-state accuracy. Computed with
respect to full GPS, RTK trajectory.
9. 1 ppm should be added to all values to account for additional error due to baseline
length.
10. Post-processing accuracy using Inertial Explorer processing soware.
