P
Enhanced
Profiles
Allows the use of enhanced INS profiles for certain applications. For
example, dead reckoning performance is controlled using the LAND Profile
and Heave filter output is controlled using the MARINE Profile.
For information about INS Profiles, see
on page 83. For
information about enabling and disabling INS Profiles, see the
SETINSPROFILE
command.
S+P
R
Relative
INS
Allows for two SPAN systems to communicate and produce a relative
solution (position, velocity, attitude) between them. This option also inherits
the enhanced profile functionality of the P model. For more information, see
S+P+R
1.2.2 IMU Grade
The IMU grade indicates which classes of IMUs are supported by the model. The IMU grade is specified as a
number between 1 and 3 to indicate the IMU grade available to the model.
So, for example, to use an ISA-100C IMU, an IMU grade of 3 is required. A larger number also allows use of any
IMU in a lower grade. So the S3 model required for the ISA-100C would also allow the use of any IMU in grades 1
and 2.
below shows the IMU grade classification.
