OEM-HG1930

SMALL, AFFORDABLE MEMS IMU

PAIRS WITH SPAN TECHNOLOGY TO

DELIVER 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.

SMALL IMU FOR DEMANDING APPLICATIONS

The HG1930 is a small, low cost Micro Electromechanical Systems (MEMS) IMU

manufactured by Honeywell. It provides tactical grade performance for unmanned

vehicles and other commercial and/or military guidance 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 MEMS Interface Card (MIC) couples the HG1930 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

can interface directly with NovAtel’s small form factor OEM615™ SPAN receiver.

The HG1930 is also available as a stand alone product so integrators can easily pair it

with an existing 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.

1. Stacked conﬁguration shown with OEM615 receiver. OEM615 sold separately.

2. 12VDC, 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.
