HOW TO GUIDE: Base Range Optimisation
This document describes the steps you can take to improve the
communication range between the mojoRTK base station and console. This
is done by explaining the beneficial configurations, pitfalls and trade-offs
that exist when setting up radio communications systems that are
applicable to the mojoRTK base to console communications.
Description
The most basic
communications scenario is to have the base station mounted on its tripod
and the communications to the console made over flat ground.
There are ways to improve the performance of the base to console
communications, some of which may be applicable to your situation and
some which are not. There as some things that you can do to improve
performance for one situation but make it worse for another.
Some background information will be provided that should help to
understand what actions you can take to improve communications
performance for the particular situation. Also, base station positions which
should be avoided will be described as they can adversely affect the radio
performance.
NOTE: This guide does not explain how to resolve issues with a
particular customer situation but provides information and concepts to
help avoid potential issues and to explain possible ways to improve
performance.
Major Points to Achieve Better Radio Performance
The major points here are listed as an initial guide and some are explained
in greater detail later.
Better performance with clear space between the base and the
console. This seems like a simple concept, however, there is
phenomena known as the Fresnel Effect or Fresnel Zones (Fresnel is
Fray-nell
pronounced
below. It is due to the Fresnel effect that mounting the base antenna
on top of a tower helps increase the base communications range.
