Extract

Although INMARSAT's founding charter includes provision for a space segment for radiodetermination, the organization has, to date, concentrated on the telecommunications aspects of its mission. However, a satellite radiodetermination (including radionavigation) services development programme has been under way for about two years, and includes both study and experimental activities. Early studies performed for INMARSAT on both passive and active radiodetermination provided a number of significant conclusions, including the rather obvious but important fact that all satellite radiodetermination concepts possess two common elements: the forward transmission (broadcast) of a relatively wideband timing/ranging signal, and the precise tracking in orbit of the satellites.
