Ashtech Z-Xtreme DGPS

Description 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. Antenna P/N: 700700(C)
