IMU-ISA-100C
HIGH PERFORMANCE TACTICAL
GRADE IMU COMBINES WITH
NOVATEL’S GNSS TECHNOLOGY TO
DELIVER 3D POSITION, VELOCITY
AND ATTITUDE SOLUTION
SPAN: WORLD-LEADING GNSS+INS TECHNOLOGY
NovAtel’s 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.
OVERVIEW
The IMU-ISA-100C features Northrop-Grumman Litef GMBH’s proven inertial
measurement technology oering exceptional performance when paired with a
NovAtel SPAN receiver. A near navigation grade sensor, the IMU-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 NovAtel’s FlexPak6™ or ProPak6™ through a highly reliable IMU
interface. IMU measurements are used by the SPAN receiver to compute a blended
GNSS+INS position, velocity and attitude solution at rates up to 200 Hz.
ADVANTAGES OF IMU-ISA-100C
The IMU-ISA-100C oers extremely high performance and precise accuracy
at an aordable price point. It is commercially exportable and oers an ideal
solution for applications such as platform stabilization, general purpose navigation,
photogrammetry, remote sensing and ground mobile mapping.
IMPROVE SPAN IMU-ISA-100C 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 SPAN IMU-ISA-100C data for the
highest level of system accuracy.
