Concepts and techniques needed to incorporate a time division multiple access (TDMA) satellite communications capability into multifunction avionics systems are being developed. Progress made during the first year of that contract is described. The work involved (1) the design and partial fabrication of prototype TDMA satellite communications modems, (2) the development of techniques and associated technological bases needed to instrument an adaptive null-steering array in which a reference signal is derived from the data-carrying signal, and (3) the development of techniques for effectively utilizing capabilities which can be provided by the TDMA satellite communications subsystem in performing satellite navigation and line-of-sight communications functions.
