  • Page 13: Chapter 1. Introduction

    Introduction Both the Z-Surveyor and the Z-FX represent a powerful and economic alternative to conventional surveying equipment for the GPS community. Designed to support an expanding variety of surveying applications, including land/boundary/cadastral surveys, route surveys, construction and as built surveys, the 12 channel, dual frequency receiver integrates technological advances in microprocessor design, data storage, and power management.

    (RTK) operation for carrier phase. The unit implements the RTCM SC 104 V2.2 standard for differential and RTK operation, including the newly defined message types 18/19 and 20/21. These features allow the Z-Surveyor and the Z-FX to achieve centimeter accuracy while being compatible for differential and RTK operation with any other receiver that implements the RTCM standard.

  • Page 15: Functional Description

    The receiver is activated when power is applied to the power connector (or internal battery has been inserted for the Z-Surveyor only), and the power push-button is pushed to ON. After self test, the receiver initializes its 12 channels and begins searching for all space vehicles (SV) within the field of view of the antenna.

When a SITE other than ???? is entered, the post processing software assumes the rover system is stationary on a point.

  • Page 82: Rapid Static Surveying

    Rapid Static Surveying The added capabilities of dual-frequency P-code found in the Z-Surveyor and Z-FX make this method of GPS surveying possible. The procedure for a rapid static survey is identical to that for a static survey, the only difference being point occupation time, thus the name rapid static.

    system, often referred to as the base, remains centered over a known point while the other system(s), often referred to as rovers, rove to unknown stations collecting short 5-10 minute data sets. In order to compute accurate baselines and establish accurate positions on the unknown points, the data collected in the field is post-processed.
