Synchronization of digital antenna controller data for applications using asynchronous interfaces

Abstract

A Global Positioning System (GPS) digital antenna controller is provided, comprising antenna electronics, a code generator, and an interface. The antenna electronics can be configured to receive a GPS signal. The code generator can be configured to generate a pilot code signal that is synchronized to the DAE local clock reference. The interface can be configured to send the GPS signal and the code signal to a GPS receiver. A system may comprise the GPS digital antenna controller and GPS receiver. The GPS receiver can comprise a second code generator and a processor configured to resolve a timing difference based on the pilot code signal and a second code signal of the second code generator. The controller may be remote from the receiver. The interface may comprise an asynchronous data interface (e.g., Ethernet, USB, Infiniband, or Firewire). To resolve the timing difference may involve GPS code and carrier tracking.
