GPS Block 2R Time Standard Assembly (TSA) Architecture

Abstract

The underlying philosophy of the GPS 2R TSA architecture is to utilize two frequency sources, one fixed frequency reference source and one system frequency source, and to couple the system frequency source to the reference frequency source via a sample data hop. The system source is used to provide the basic clock frequency and timing for the space vehicle (SI/) and it uses a VCXO with high short term stability. The reference source is an atomic frequency standard (AFS) with high long term stability. The architecture can support any type of frequency standard.
