IMU-ISA-100C Product Sheet

IMU-ISA-100C
High performance tactical grade
IMU combines with SPAN technology
from Hexagon | NovAtel to deliver 3D
position, velocity and attitude solution
World-leading GNSS+INS technology
SPAN GNSS+INS technology brings together two different but complementarytechnologies: 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 deeply
coupled to provide an exceptional 3D navigation solution that is stable andBenefits• Premium performance IMU• Optimal for aerial, hydrographic
survey and industrial applications

continuously available, even through periods when satellite signals are blocked.
• Easy integration with NovAtel’s SPANOverview
The IMU-ISA-100C features Northrop-Grumman Litef GMBH’s proven inertial
measurement technology offering exceptional performance when pairedwith a NovAtel SPAN enabled receiver. A near navigation grade sensor, theIMU‑ISA‑100C contains fiber optic gyros and fully temperature compensated Micro
Electromechanical Systems (MEMS) accelerometers. The IMU-ISA‑100C operates
from 10-34 VDC and interfaces with a receiver from NovAtel through a highly reliablecapable GNSS+INS receivers• Commercially exportable• Rugged design ideal for challengingenvironments• Ideal for a control reference system

IMU interface. IMU measurements are used by the SPAN enabled receiver tocompute a blended GNSS+INS position, velocity and attitude solution at rates up to200 Hz.

Advantages Of IMU-ISA-100CFeatures• Low noise fiber optic gyros and MEMS
accelerometers

The IMU-ISA-100C offers extremely high performance and precise accuracy at anaffordable price point. It is commercially exportable and offers an ideal solution
for applications such as platform stabilization, general purpose navigation,
photogrammetry, remote sensing and ground mobile mapping.

Improve IMU-ISA-100C accuracy
Receivers from NovAtel provide your choice of accuracy and performance, fromdecimetre to RTK-level positioning. For more demanding applications, Waypoint
Inertial Explorer post-processing software can be used to post-process real-timedata on the IMU-ISA-100C for the highest level of system accuracy.

• Stationary INS alignment capable• IMU data rate: 200 Hz• Enclosure comes with optional wheel
sensor input• SPAN GNSS+INS capability withconfigurable application profiles

1. Typical values. Performance specifications subject to GNSS system characteristics, Signal-in-Space (SIS) operational degradation, ionospheric and tropospheric conditions, satellite geometry, baseline length, multipath effects andthe presence of intentional or unintentional interference. 2. GPS-only. 3. Requires a subscription to TerraStar data service. Subscriptions available from NovAtel. 4. TerraStar service available depends on the SPAN enabled receiverused. See the receiver product sheet for details. 5. 400 Hz data is an optional configuration. Contact NovAtel for details. 6. Time accuracy does not include biases due to RF or antenna delay. 7. Export licensing restricts operation toa maximum of 515 metres/second. 8. Supplied by IMU manufacturer. 9. GNSS receiver sustains tracking up to 4 g. 10. Ground Mobile Operating Environment. 11. 1 ppm should be added to all values to account for additional error dueto baseline length. 12. Post-processing results using Inertial Explorer software.
