GNSS Planning
Online Tool
During peaks of solar activity,
where certain portions of
the ionosphere are excited,
higher signal delays will occur.
While ionospheric activity may
typically occur at key times
throughout the day, such as
midday or dusk, that is not
always the case. Trimble has
setup a global ionospheric
measurement network,
which via the GNSS Planning
Online (gnssplanning.com)
tool allows users to plan ahead
and avoid working during
times where there is higher
probability of disturbance.
Above is an example of a map of TEC from the planning tool.
An ionospheric index value for a given location and time is also provided.
This is a value on a scale of zero to 10 indicating ionospheric level
derived from measured TEC and scintillation.
