Conclusion
In equatorial and high latitude regions of the
world, ionospheric disturbances are common
with peak activity during solar storms and 11
year cycle maximums.
Industries with high operating costs such as mining and agriculture
require centimeter level accuracy 24 hours per day. Unfortunately
high precision GNSS is affected most by these disturbances and with
increasing solar activity, the problem could become more global and
expensive in nature.
Utilizing a global network of GNSS stations, Trimble's GNSS Planning Tool
allows users to identify and plan around high ionospheric activity.
Trimble has taken further actions to ensure its customers GNSS
accuracy and availability through the development of IonoGuard
technology. An ongoing data collection campaign has provided GNSS
and RF data to tune signal processing and RTK algorithms and deliver
improved accuracy, availability and integrity. Diagnostic information
indicating the real time level of ionosphere on each satellite together with
historical data is presented in a user friendly graphical web interface.
IonoGuard technology in operation around the world has already shown
significant improvements in positioning performance during the periods
of high ionospheric activity. Users can feel confident that the superior
performance of their ProPoint receivers has been further improved with
the addition of IonoGuard ionospheric mitigation technology.
