Abstract

Operational satellite geodesy is based upon data transmitted from the satellite to the user by means of electromagnetic waves. Some of the factors describing the physical behaviour of these waves are presented in Table 5.1 together with their symbols and dimensions. Note that integer cycles are equivalent to multiples of 2π radians. Another unit for cycles per second (cps) is Hertz (Hz) or decimal multiples according to the rules of the International System of Units (ISU). Equation (5.1) relates the parameters shown in Table 5.1:
$$f = 2\pi \frac{1}{P} = \frac{c}{\lambda }.$$
