The GNSS technology can be harmed by some natural phenomena, mainly solar flares and anomalous variations in the thickness of the terrestrial ionosphere. One of these phenomena is Scintillation, which seriously compromises the accuracy of the GNSS coordinates, even more when the system is corrected by a RTK base.
One way to minimize the effect of Scintillation in rovers RTK is to replace the RTK corrections with a paid signal (IsoPoint 3), since this type of correction uses several bases spread across the globe and manages to minimize the Scintillation effect of a certain geographical point.
The IsoView system has the Scintillation Forecast feature, through which it is possible to determine a scheduled start time of the daily Scintillation phenomena and the duration time in which RTK corrections will be disabled, causing the position to be automatically corrected during this period by the IsoPoint 3 paid signal.
If the Scintillation Forecast parameter is disabled, the RTK Configuration menu is shown as in the following image.
Pressing the edit button 
, the Scintillation Forecast setting screen will be displayed, as shown in the image below.
Start Time
Selecting the option Period and pressing the confirm button 
, the user will be asked to configure the start time of the Scintillation Forecast, through two screens of Vertical choice, for hours and minutes, as shown in the images below.
Hours of Operation
After configuring the start time for Scintillation Forecast, the RTK Configuration screen will be displayed as shown in the following image. A new field called Hours of Operation will appear, through which the user decides for how many hours, between 1 and 6, the Scintillation Forecast will be effective.
Selecting Hours of Operation item and pressing the edit button , a Vertical choice screen will be displayed, to configure the number of hours of the Scintillation Forecast feature, as shown in the following image.
After configuring the number of operating hours, the Scintillation Forecast setting will be completed and will be effective in the established time period defined by the user.
