  • Page 17: Chapter 1. Introduction

    Introduction The Reliance system provides full-featured capability for rapid and precise GIS data acquisition. Reliance makes it possible for a minimally trained worker to rapidly collect accurate data on the location and attributes of point features such as trees and fire hydrants, line features such as roads and power lines, area features such as city blocks and lakes, and nested points or lines within a line or area.

  • Page 27: Chapter 2. Survey Planning

    Survey Planning Reliance is a very versatile, cost effective system that allows for several levels of accuracy during a single surveying session. Table 2.1 lists system requirements. Table 2.1: Reliance Requirements Submeter Decimeter Precision • Corresponding epoch • P option installed in SCA-12 •...

    practically eliminated. If for some reason, the Reliance Processor cannot successfully resolve measurement ambiguities, the system will automatically revert to Decimeter processed results. Although data collection for cm processing can be time consuming, it is very rewarding in terms of accuracy. There simply is no faster, easier way to achieve precise, GIS ready asset positioning than with Reliance CM Processor.

  • Page 30: Data Logging Guidelines

    Data Logging Guidelines Many new users inadvertently create multiple fragmented receiver files, each containing only a few minutes of GPS data and a handful of features. Feature accuracy is compromised because the processor can not properly post-process these fragmented files. To avoid multiple receiver files, follow these guidelines: •...

  • Page 31: Improving Feature Accuracy

    • Do not change the Data to Log type on the Receiver Setup screen while a session is in progress. This setting should always be Code Only (or Code & Carrier, depending on the receiver option you purchased) if the data is going to be post-processed.

  • Page 32: Tips For Maximizing Centimeter Accuracy

    • While logging a point feature, keep the GPS antenna as motionless as possible. • Record at least thirty minutes of data in each session. Even if only a few minutes of feature data are logged, let the receiver collect at least thirty minutes of data for more accurate post-processing.

  • Page 33: Gps Under Trees

    GPS under Trees GPS receivers are not at their best in forests. Signals from the GPS constellation must be able to reach the receiver for it to produce a position fix. If you’re behind a ridge, building, or other solid mass, those signals won’t get through. Trees, on the other hand, vary in their ability to obscure and disrupt the acquisition of position fixes.
  • Page 34 and areas are not as detailed. The base station recording interval must be less than or equal to the rover recording interval for post-processing of all collected data. Q: How many sessions can I record? A: The receiver can record up to 100 sessions or until the receiver memory is full. The number of sessions in a project is limited only by the memory available on the Q: How far away from the base station can I be and still get accurate positions? A: As the distance to the base station increases, the post-processed accuracy...

  • Page 36 The first is known as Post Processed Differential, the latter as Real-Time Differential. Each is useful, although post-processing is the most common, reliable, and proven method now available. Ashtech receivers operate in either mode. Reliance with FS/2 Field Operations Manual...
  • Page 37 The theory behind differential correction is simple. At least two receivers must operate at the same time, with one unit located on a known point. Both receivers must use the same set of satellites to derive positions. In post-processed differential, GPS data collected on the known point (by a receiver usually referred to as a reference station) is used, after the field survey is completed, to remove inaccuracies from the field data.
  • Page 38 Q: What’s an epoch? A: When looking at GPS data, epoch refers to a particular unit of acquired data. An epoch of data from a receiver is one set of measurements, commonly one second’s worth, although many users in the GIS community work at five-second intervals. Whatever the interval between samples, an epoch is the same, the measurement at that time.
