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)

Garmin GPS devices are handheld or mounted navigation units that use Global Navigation Satellite Systems (including GPS, GLONASS, Galileo) to provide accurate positioning for outdoor activities, field surveys, and scientific research. Standard handheld Garmin units (e.g., GPSMAP 65, eTrex 32x) typically achieve 1–3 m accuracy, suitable for most fieldwork applications. Advanced models support multi-band GNSS for improved precision in challenging environments (e.g., dense canopy, rugged terrain)
