NovAtel SPAN GNSS Inertial Navigation Systems

Item# SPAN

NovAtel's SPAN® technology couples OEM precision GNSS receivers with robust Inertial Measurement Units (IMUs) for reliable, continuously available, position, velocity and attitude -- even through short time periods when satellite signals are blocked or unavailable. View Full Description

Category: IMU
Manufacturer: NovAtel
Manufacturer Number: SPAN


NovAtel's SPAN® Technology

NovAtel's SPAN technology provides continuous 3D position, velocity and attitude determination even when satellite reception may be compromised for short periods of time. 

SPAN® integrates NovAtel's industry leading Global Navigation Satellite System (GNSS) technology with Inertial Measurement Units (IMUs) to create a tightly coupled GNSS INS solution at data rates up to 200 Hz. A range of receiver, IMU and antenna options are available to meet accuracy and size requirements for nearly any application.

The accuracy of SPAN products can be optimized with best-in-class post-processing software from our Waypoint® Products Group.


GNSS Solution
With GNSS only positioning, navigating becomes unreliable or impossible when satellites are blocked by obstructions such as trees or buildings.

Drifting INS Solution
In the absence of an external reference, the Inertial Navigation System (INS) solution will drift over time due to accumulated errors in the IMU data.

Continuously available and following the true path

SATELLITE Line-of-Sight

When combined, the two navigation techniques augment and enhance each other to create a powerful positioning system. The absolute position and velocity accuracy of the GNSS is used to compensate for the errors in the IMU measurements. The stable relative position of the INS can be used as a bridge to span times when the GNSS solution is degraded or unavailable. Data is available in real-time or can be post-processed for workflows requiring the most robust solution possible and additional quality control.
