LDACS APNT Architecture Development & Evolution

Abstract

This paper presents recent developments towards an LDACS Alternative Positioning, Navigation and Timing (APNT) capability. The focus is on refinement of key error budget components including multipath and airborne radio clock estimation error from two-way timing and ranging processing. In addition, the impact of airborne radio transmitter power control on ranging errors and operational APNT availability is assessed.
