IMU-LN200

TACTICAL GRADE, LOW NOISE IMU

COMBINES WITH NOVATEL’S GNSS

TECHNOLOGY TO PROVIDE 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 Systems (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.

IMU-LN200 OVERVIEW

The IMU-LN200 is a tactical grade IMU containing closed-loop ﬁber optic gyros

and solid-state silicon accelerometers. Low noise and stable accelerometer and gyro

sensor biases make the IMU-LN200 an ideal choice for airborne mapping applications.

IMU mounting is made easy by its small footprint.

The IMU-LN200 is available as a complete assembly, including the IMU and

environmentally sealed enclosure. The LN200 is also available as a stand alone OEM

product so integrators can easily pair it with a SPAN enabled receiver. The LN200 is

ITAR controlled and requires export approval for customers outside the United States.

IMPROVE SPAN LN200 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 LN200 data and oers the highest level of

accuracy with the system.

Low noise, low bias sensor excellent

for airborne survey applications

1. Typical values. Performance speciﬁcations subject to GPS system

characteristics, US DOD 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. GNSS receiver sustains tracking up to 4 g.

9. Steady state and outage performance remains the same for the C model.

10. 1 ppm should be added to all values to account for additional error due to baseline

length.

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