CUSTOM MULTI-SOURCE MODE CONFIGURATION 3.5.4
For applications in which the standard Single- Dual- and Local-Source mode are not quite right, VIPER™ can be
configured to operate in a custom user-selected Multi-Source mode.
Multi-Source behavior is defined on a per-Sensor basis by two settings that may be manually configured:
SOURCE SELECT defines which Source(s) a Sensor detects for determining P&O.
SENSOR ORIGIN defines which Source serves as the Sensor’s referenced Cartesian position origin (0, 0, 0) and
null orientation.
Both of these settings are configured using VIPER™ configuration commands SOURCE SELECT and SENSOR
ORIGIN. These commands and settings are detailed in Section 4.2.14.
EXPANDED TRACKING AREA MULTI-SOURCE MODE 3.5.5
In the previous three modes of operation, connected VIPER™ Sources are used as individual units, each one
defining a separate frame of reference for Sensor P&O. As such, each “Source tracking volume” is limited in size
and shape by the strength of the EM field emitted by that Source.
For applications that require an expanded tracking area, the connected VIPER™ Sources can be configured
together to define a single expanded tracking volume and frame of reference for all Sensors.
The SOURCE CONFIGURATION command allows the user to specify the position and orientation of each
connected Source relative to a user-defined virtual frame of reference. The reference frame may correspond to
one of the Sources or it may be a virtual point implied by the position configurations for the Sources in the
system. The SOURCE CONFIGURATION command is detailed in Section 4.2.7.
Note: VIPER™ operates in Expanded Tracking Area Mode whenever SOURCE
CONFIGURATION is applied to the system, regardless of the pattern of
connected Sources.
