A Possible Impact of the Joint Tactical Information Distribution System (JTIDS) on ASTRO-DABS

Abstract

The development of the ASTRO-DABS concept to date has assumed availability of the Aeronautical L-band. Due to its increased usage, however, consideration is being given to operating ASTRO-DABS in the TACAN band, a portion of the frequency spectrum which is also being considered for use by the military program JTIDS (Joint Tactical Information Distribution System). Because of JTIDS operating characteristics, there is concern that ASTRO-DABS performance may be impaired. The present report presents a preliminary analysis, and corresponding numerical results, as to the impact of JTIDS on ASTRO-DABS. Areas for possible future investigation, and means for more detailed analyses, are also included. The preliminary indications, however, are that coexistence of ASTRO-DABS and JTIDS in the same frequency band would severely degrade the downlink (satellite-to-aircraft) performance of ASTRO-DABS.
