COLUMNS FORMAT DESCRIPTION DEFAULT VALUE & UNITS
1-5 A5 TIDES - Modifies Earth tide
perturbation and requests application
of pole tide.
7-8 I2 Indicates which tidal coefficient 0
to be modified.
VALUE COEFFICIENT
20 K2 amplitude
21 K2 phase
30 K3 amplitude
A value of 0 sets all coefficients
(K2 amplitude, K2 phase and
K3 amplitude) to zero. [1]
9-10 I2 A value of 1 means that the pole tide is 0
applied to correct the station positions.

TIDES (cont)
NOTE [1]: It is sufficient to turn on the pole tide in one card (even if more
TIDES option cards are included in the setup).
NOTE [2]: These default values apply only to earth tracking stations. In case
of other planetary stations the default values are zero.
UNITS: KM =Kilometers; M =Meters ; S =Seconds ; M/S=Meters per second
DEG=Degrees ; RAD=Radians ; AS =Arc seconds; MAS=Milli-arc seconds
IF CARD OMITTED: Default values given above are used, and pole tide will not
be applied.
