# Please note the following explanations
# *********************************************************************************************************
#  1.) Source(S): ITRF2020 or IGS20 (epoch tc) Target(T): ETRS89/DREF91(R2016)
#
#  2.) Transformation formula (|Matrix signs|):
# |X(T)|   |TX'|   | D'     RZ'  -RY'|   |X(S)|   |X(S)|
# |Y(T)| = |TY'| + |-RZ'    D'    RX'| * |Y(S)| + |Y(S)|
# |Z(T)|   |TZ'|   | RY'   -RX'   D' |   |Z(S)|   |Z(S)|
#
# Whereby:
#  3.) X(T), Y(T), Z(T) = Coordinates Target
#  4.) X(S), Y(S), Z(S) = Coordinates Source
#  5.) TX' = TX+vTX*(tc-t0)  Translation in X at observation epoch
#  6.) TX  =                 Translation in X at reference epoch
#  7.) vTX =                 Velocity of TX at reference epoch
#  8.) TY' = TY+vTY*(tc-t0)  Translation in Y at observation epoch
#  9.) TY  =                 Translation in Y at reference epoch
# 10.) vTY =                 Velocity of TY at reference epoch
# 11.) TZ' = TZ+vTZ*(tc-t0)  Translation in Z at observation epoch
# 12.) TY  =                 Translation in Z at reference epoch
# 13.) vTY =                 Velocity of TZ at reference epoch
# 14.) RX' = RX+vRX*(tc-t0)  Rotation angle in X at observation epoch
# 15.) RX  =                 Rotation angle in X at reference epoch
# 16.) vRX =                 Velocity of RX at reference epoch
# 17.) RY' = RY+vRY*(tc-t0)  Rotation angle in Y at observation epoch
# 18.) RY  =                 Rotation angle in Y at reference epoch
# 19.) vRY =                 Velocity of RY at reference epoch
# 20.) RZ' = RZ+vRZ*(tc-t0)  Rotation angle in Z at observation epoch
# 21.) RZ  =                 Rotation angle in Z at reference epoch
# 22.) vRZ =                 Velocity of RZ at reference epoch
# 23.) D'  = D +vD *(tc-t0)  Difference in scale (1 + s) at observation epoch
# 24.) D   =                 Difference in scale (1 + s) at reference epoch
# 25.) vD  =                 Velocity of D at reference epoch
# 26.) tc  = Epoch of observation (Fractional of year, e.g. 2022.47)
# 27.) t0  = Reference epoch (Fractional of year, e.g. 2022.0)
#
# 28.) Note: All rotation angles must be converted to radians before calculation ( 1 mas = 4.847309743 x 10-9 rad)
#
# 29.) Also important: 0 < (tc-t0) <= 1 year 2 month
