IMU-HG1900

TACTICAL GRADE MEMS IMU

COMBINES WITH SPAN TECHNOLOGY

PROVIDING 3D POSITION, VELOCITY

AND ATTITUDE

ABOUT 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 Systems (INS). The absolute accuracy of

GNSS positioning and the stability of Inertial Measurement Unit (IMU) measurements

combine to provide an exceptional 3D navigation and attitude solution that is stable

and continuously available, even through periods when satellite signals are blocked.

SOPHISTICATED, TACTICAL GRADE MEMS PERFORMANCE

The IMU-HG1900 IMU oers a hybrid package of Honeywell’s Micro

Electromechanical Systems (MEMs) Gyros and RBA accelerometers. Economical,

robust and small, the low power IMU-HG1900 provides high end tactical grade

performance for commercial and military guidance and navigation applications.

When integrated with NovAtel’s SPAN technology, this IMU is ideal for airborne and

ground applications that require accurate 3D position, velocity and attitude data. The

IMU-HG1900 is ITAR controlled and requires export approval for customers outside

the United States.

The IMU-HG1900 is available as a complete assembly in an environmentally sealed

enclosure. The HG1900 is also available as a stand alone OEM product that can be

easily paired with a SPAN enabled GNSS receiver.

IMPROVED ACCURACY

Take advantage of NovAtel CORRECT™ to receive your choice of accuracy and

performance, from decimetre to RTK-level positioning. For the most demanding

applications, Inertial Explorer® post-processing soware from our Waypoint® Products

Group oers the highest level of accuracy.

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 eects

and the presence of intentional or unintentional interference sources.

2. GPS-only.

3. Requires subscription to TerraStar data service. Subscriptions available from

NovAtel.

4. TerraStar service available depends on the SPAN receiver used. See the receiver

product sheet for details.

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. Outage statistics were calculated by taking the RMS of the maximum errors

over a minimum of 30 complete GNSS outages. Each outage was followed by

120 seconds of full GNSS availability before the next outage was applied. High

accuracy GPS updates (ﬁxed ambiguities) were available immediately before

and aer each outage. The survey data used to generate these statistics is

ground vehicle data collected with frequent changes in azimuth (i.e., as normally

observed in ground vehicle environments).

9. 1 ppm should be added to all values to account for additional error due to baseline

length.

10. Post-processing results using Inertial Explorer soware.
