ABOUT SPAN: TIGHTLY-COUPLED 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.
LOW NOISE COMMERCIAL MEMS
The STIM300 is a Micro Electromechanical System (MEMS) IMU from Sensonor. It
features low noise gyros and accelerometers in a small, lightweight, environmentally
sealed enclosure. The STIM300 enables precision measurements for applications that
require low cost, high performance and rugged durability in a very small form factor.
When integrated with NovAtel’s SPAN technology, this IMU is ideal for airborne and
ground applications that require accurate 3D position, velocity and attitude (roll, pitch
and azimuth) data.
COMBINING SPAN AND MEMS TECHNOLOGY
A proprietary NovAtel MEMS Interface Card (MIC) couples the STIM300 with
SPAN receiver cards, 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.
REQUIRE HIGHER 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®
Products Group oers the highest level of accuracy.

1. Stacked configuration shown with OEM615 receiver. OEM615 sold separately.
2. With OEM615 supplied 10 V.
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
200 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. Outage performance information is applicable to firmware version
OEM060240RN0000 and up.
7. 1 ppm should be added to all position values to account for additional error due
to baseline length.
8. Post-processing accuracy using Inertial Explorer processing soware. 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).
