OEM-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 PERFORMANCE

The 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 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.

COMBINING SPAN AND MEMS TECHNOLOGY

A proprietary NovAtel MEMS Interface Card (MIC) couples the HG1900 with

SPAN receivers, oering a unique, powerful GNSS+INS system for weight and

size constrained applications. Designed as a board stack conﬁguration for ease of

integration, the MIC interfaces directly with NovAtel’s small form factor OEM615™

SPAN receiver.

The HG1900 is also available as a stand alone product so integrators can easily pair it

with an existing OEM6® SPAN receiver.

REQUIRE HIGHER 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.

2. 12 VDC, OEM615 stack conﬁguration

3. OEM615 USB port in stack conﬁguration

4. Supplied by IMU manufacturer.

5. 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).

6. 1 ppm should be added to all values to account for additional error due to baseline

length.

7. Post-processing results using Inertial Explorer soware.
