3.4.3 Setup of configuration parameters
Setup consists of:
•
Installing the setup software SCC on an external PC.
•
Entering lever arm vectors and mounting angles for the MRU and the GPS antennas.
•
Entering input and output data interface.
The setup parameters are entered into the Seapath Processing Unit by utilising the
configuration software SCC. The SCC software is described in "Appendix D - Seapath
configuration software, SCC"
.
Always fill in the setup parameters for the specific installation in the Seapath Installation
Worksheet before entering the setup software. Fill in the parameters directly in the worksheet
found in the "Appendix A - Installation worksheet" in the manual. In this way, the parameters
for the actual installation will be easier to find when requested later.
3.4.3.1 Lever arm vector determinations
The following lever arm vectors have to be determined and input to the configuration
software SCC:
•
The vector from the centre of gravity to the GPS antenna no. 1.
•
The vector from the centre of gravity to the MRU location.
•
The vectors from the centre of gravity with up to maximum four measurement points.
All these vectors have to be measured or calculated based upon drawings or previously
measured points. These vectors are to be measured within an accuracy of 0.5 metres or better.
Positive vector orientation for these parameters is X - positive forwards, Y - positive towards
starboard, Z - positive downwards with the centre of gravity as the origin.
Note
If data shall be valid for centre of gravity, it is not necessary to define a zero
measurement point vector since the data is default output in CG. The antenna and
MRU vector have to be measured in any case.
