摘要：
An apparatus includes: a Global Positioning System (GPS) phased array comprising a plurality of digital beam forming elements (DBFEs), wherein at least one of the DBFEs includes: an antenna configured to transmit a GPS signal; a radio frequency (RF) electronics section operably connected to the antenna and digital electronics sections; and a digital electronics section operably connected to the RF electronics section. An apparatus includes: a GPS phased array comprising a plurality of DBFEs, wherein at least one of the DBFEs includes: an antenna configured to transmit a GPS signal; an RF electronics section operably connected to the antenna and digital electronics sections; and a digital electronics section operably connected an RF electronic section; a navigation encoder and frequency generator (NEFU) unit operably connected to the GPS phased array; and an atomic frequency standard operably connected to the NEFU unit.
