or SBAS setup and operation.
With no additional configuration, the system operates in single point mode.
3.3.2 INS Profiles
INS Profiles provide two major functions; simplified configuration and enhanced performance. Each INS Profile
sets specific filter behavior to enhance system performance in particular environments.
Basic enhancements provided by the INS Profiles are available to all SPAN enabled models and allow for simple
configuration rather than sending many discreet commands.
The enhanced profile settings are enabled by the receiver model. The enhanced profile adds enhanced profile
behavior such as Dead Reckoning for land and Heave for marine. A receiver model with an INS Mode of
P
or
R
is required to enable Enhanced INS Profiles.
