Position-reference system
Position information from the GPS position-reference system provides position
information as Latitude and Longitude in a geodesic coordinate system.
System datum
The controller PS always uses an internal geographic coordinate system, that uses
WGS84 as a “system datum”.
All position information from global reference systems which use a different datum are
converted internally to WGS84.
Reference origin
The position-reference system provides position measurements relative to a known
reference point. When the position-reference system is selected and accepted for use with
the system, it becomes the reference origin (the origin in the internal coordinate system).
Tests on position measurements
The system performs a series of tests on the position-reference system to check that its
position measurements are accurate enough for use.
The following online tests are performed:
• A
freeze test
rejects repeated measurements. If the variation in the measured position
is less than a system set limit over a given period of time, the position-reference
system is rejected.
• A
variance test
monitors the measurement variance and compares the variance value
with a calculated limit.
