The t
d-AN
is used to check the miss-detection, where it implies the relative position from
the equator, while the tile ID indicates the hemisphere of north or south. For tiles of the
northern hemisphere in ascending tiles (i.e., tile ID = T00**~T08**), if the t
d-AN
is greater
than a threshold T
N
, the number of RSP-path is detected being shifted backward and
is added by N. For tiles of the southern hemisphere (i.e., tile ID = T09**~T17**), if the
t
d-AN
is less than a threshold T
S
, the number of RSP-path is detected being shifted
forward and is subtracted by N. Both of T
N
and T
S
are set to 3000 seconds as approx.
the half of the period of orbit cycle.
Note that this algorithm does not support the “RSP shifts” that temporarily occurred
because of non-routine orbital maneuvers. In that period, the number of RSP-path has
the error of +1. The details of the “RSP shift” can be found at:

See records that the Comments = “RSP is 1 more than nominal” at Table 1.
