UIMU-HG1700

ECONOMICAL, TACTICAL GRADE IMU

COMBINES WITH NOVATEL’S GNSS

TECHNOLOGY TO DELIVER 3D POSITION,

VELOCITY AND ATTITUDE SOLUTION

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. 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.

UIMU-HG1700 OVERVIEW

The UIMU-HG1700 contains the Honeywell HG1700 IMU. The HG1700 is a tactical

grade IMU containing ring-laser gyros and servo accelerometers. The UIMU-HG1700

handles the power requirements of the IMU from a 12-28 VDC power input and

provides the IMU data to a SPAN enabled GNSS+INS receiver such as the FlexPak6™

or ProPak6™ using a custom NovAtel interface. IMU measurements are used by the

GNSS+INS receiver to compute a blended GNSS+INS position, velocity and attitude

solution at up to 100 Hz. The HG1700 is ITAR controlled and requires export approval

for customers outside the United States.

ADVANTAGES OF UIMU-HG1700

The HG1700 IMU is available in a range of gyro performance levels from one to ﬁve

degrees per hour. Honeywell’s high production volume of HG1700 IMUs enables

excellent tactical grade performance for an economical price with short delivery

times. The UIMU-HG1700 is available as a complete assembly including the IMU and

environmentally sealed enclosure. For customers who already have the HG1700 IMU,

the enclosure can be purchased separately and the IMU easily integrated.

IMPROVE SPAN UMIU-HG1700 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® Product

Group can be used to post-process SPAN UIMU-HG1700 data and oers the highest

level of accuracy with the system.
