|13CCH04||Ashtech Z-Xtreme DGPS|
The Z-Xtreme processes signals from the GPS satellite constellation, deriving
real-time position, velocity, and time measurements. Twelve dedicated separate
and parallel channels extract Coarse/Acquisition (C/A) code-phase, and carrierphase
measurement on the L1 (1575 MHz) band, and Precise (P) code phase
and carrier phase measurement on the L1 and L2 (1227 MHz) bands.
The Z-Xtreme receives satellite signals via an L-band antenna and low-noise
amplifier (LNA). The receiver operates stand-alone and as a base (reference)
station or remote (rover) station providing real-time differential GPS operation for
code, and real-time kinematic (RTK) operation for carrier phase. The unit
implements the RTCM SC 104 V2.2 standard for differential and RTK operation.
These features allow the Z-Xtreme to achieve centimeter accuracy while being
compatible for differential and RTK operation with any other receiver that implements the RTCM standard.
