OEM-IMU-HG4930P
SMALL, AFFORDABLE 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 dierent 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) gyro and
accelerometer measurements combine to provide an exceptional 3D navigation
solution that is stable and continuously available, even through periods when satellite
signals are blocked.
SOPHISTICATED, TACTICAL GRADE MEMS PERFORMANCE
The OEM-IMU-HG4930P is a high performing Micro Electromechanical Systems
(MEMs) IMU. Economical, robust and small, the low power OEM-IMU-HG4930P
provides tactical grade performance for unmanned vehicles and commercial and/or
military guidance applications. When integrated with NovAtel’s SPAN technology, this
IMU is ideal for airborne, marine and ground applications that require accurate 3D
position, velocity and attitude data in a compact package.
OEM-IMU-HG4930P ADVANTAGES
The OEM-IMU-HG4930P is comprised entirely of commercial components,
simplifying export processes for this IMU.
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 soware from our Waypoint®
Products Group oers the highest level of accuracy.

4 Time accuracy does not include biases due to RF or antenna delay.
5 Export licensing restricts operation to a maximum of 515 metres/second.
6 Supplied by IMU manufacturer.
7 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 aer 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).
8 1 ppm should be added to all values to account for additional error due to baseline length.
9 Post-processing results using Intertial Explorer. 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 vehilce environments).
