Note 1.
Original precision is retained for compatibility with previous Polhemus 3SPACE
systems. Also, note that some item values are repeated as extended precision items, although no
output difference is made (i.e., space, <cr lf>. Original and extended precision may be freely
mixed in an output record, but it is recommended that extended precision be used if compatibility
is not required, as the original precision may be deleted in future systems.
Note 2.
This code will in general output the last error that the system BIT (Built-In-Test)
routines found prior to the output of this system data record. If any BIT clearing has been
commanded (see the
‘T’ – Built-In-Test Information
), the system will search
for an error that is currently set, starting at the largest numeric error code value, and then output
the first error code found in the search that is set. See
‘T’ – Built-In-Test Information
, page
for specified definitions of each error code.
Note 3.
Items 5, 6, and 7 or 55, 56, and 57 may be obtained to construct the line-of-sight, line-of-
hear, and line-of-plumb vectors as follows:
Three (3) values are obtained from each item above.
Item 5 or 55 = | 5a 5b 5c | | 55a 55b 55c |
Item 6 or 56 = | 6a 6b 6c | | 56a 56b 56c |
Item 7 or 57 = | 7a 7b 7c | | 57a 57b 57c |
Then the a-column above is the line-of-sight vector, the b-column above is the line-of-hear
vector, and the c-column above is the line-of-plumb vector.
