X measurement If the direction from the antenna to the datum line is to starboard the sign is positive Then measure from the antenna parallel to the longitudinal axis of the vessel to the datum this is the Y axis measurement If this is towards the stern the sign is negative Enter the height of the antenna above the Center of Rotation of the vessel This value is normally negative since the direction of the measurement is normally down C Scape Manual Version 1 10 Page 52 of 86 11 26 2012 Like all C Scape linear measurements they follow the units of the current map projection Thus for Gulf of Mexico operations using the default projections linear units are feet These steps are shown graphically as a reminder on the Diagram tab Although this illustration references the GNSS antenna the range bearing sensors are treated in the same manner GPS Accuracy Input Two values are required for GNSS accuracy one is unaided and the other is with the differential correction system in use Both values should be the accuracy at a HDOP value of 1 0 These values are used in the weighting calculations GPS GyroCompass Accuracy Input Two values are required for GNSS GyroCompass accuracy similar to Heading Sensors The correction value is added algebraically to the raw measured data The Nominal Accuracy is a weight used when blending all of the heading sensors together GPS GyroCompass Accuracy is only available if the device is a Hemisphere

GPS device C Scape Manual Version 1 10 Page 53 of 86 11 26 2012 Heading Sensor Setup The system supports the use of up to 3 heading sensors These can be all the same type of sensor or a mixture of types For each sensor the user can enter a correction value and a nominal accuracy The correction value is added algebraically to the raw measured data This is normally the value obtained during a gyro calibration and is the sum of any misalignment error and measurement error The Nominal Accuracy entry allows the system to properly weight data from heading sensors of differing accuracy values If all sensors are the same type then enter the same value for each Sensor Control Currently two GNSS position sensors can be combined in a weighted solution to produce the best fit Heading from up to three heading sensors are also weighted to give a single heading output Position and Heading solutions are accessed by clicking on the appropriate tab C Scape Manual Version 1 10 Page 54 of 86 11 26 2012 It is fundamental to the system that there is always at least 1 positioning system included in the solution At start up the system looks at GNSS 1 GNSS 2 INS 1 then INS 2 in that order The first system assigned an I O port is included in the position solution all others are initially excluded Heading sensor 1 is also automatically selected at start up The system will not allow the user to take the sole remainin
