Overview of the IS-1500
The IS-1500 Natural Feature Tracker (NFT) is a motion tracking system that uses both visual and inertial input to calculate and
output position and orientation data. The system enables GPS-denied tracking and navigation in a free-roaming environment. The IS-
1500 kit includes an InertiaCam tracker, a USB-C 2.0 cable, a fiducial poster, and a sensor fusion software suite.
The InertiaCam is an optical-inertial 6-DOF (six degrees of freedom) motion tracker. It pairs a monocular camera with a specially
developed InterSense inertial measurement unit (IMU), known as the NavChip. There is a female USB-C connector at the base of the
InertiaCam used to connect to the host computer.
InertiaCams have limited internal processing capability. The majority of image and inertial data processing is performed by the
sensor fusion software installed on the host computer. The flow chart in Figure 2 provides an overview of the IS-1500 system
architecture. The arrows indicate the flow of the data processing chain, beginning with sensory input from the InertiaCam and
ending with the output of tracking data.
