What can be expected regarding the performance of your GNSS receiver?
Expected difficulties are a decrease in the stability of the position Fix, decreased precision, and a longer time to achieve a fixed solution.
Cycle slips may also be encountered, degrading the solution's quality. Using more satellite constellations will make the solution more robust and improve the performance of the GNSS receivers during such events.
What can be done to mitigate any effects of these events?
The effects change daily and occur at various times of the day.
The use of GNSS planning tools is recommended to help lessen the effects.
Keep GNSS receivers updated on the latest available firmware. (Email our service department to find out if you have the latest firmware available on your unit)
How long do these events last for?
A solar flare event can last from a few minutes to hours. The sun's active region can produce flares that can last up to several weeks.
The impact of these events will vary between locations.
Recommended Action:
While technology is constantly improving and Topcon continues to work on solutions to improve system performance and minimize the negative effect of any GNSS error source, complete mitigation of these events is not possible.
We can summarise our recommendations as follows:
- Keep GNSS rover up to date
- Reduce baseline distance between the BASE and the Rover.
- Use multi-constellation signals
- For currently high solar activity, plan the field activities for a time with less solar impact.
