It's getting hot on the sun...the activities of the sun are currently stronger than would be expected at the current time. The solar cycle and current activity presents us with some
Problems, especially when it comes to satellite-based technologies such as Global Satellite Systems and Real Time Kinematics (RTK). One challenge when using GNSS and RTK, for example, is the so-called “time to fix” – i.e. the time required to establish a clean connection between the satellite, the receiver and the correction data service (e.g. SAPOS).
The reason for these problems lies in the effects of the solar cycle on the earth's atmosphere. During the solar cycle there is increased activity on the Sun, which in turn leads to increased solar radiation and geomagnetic storms. These storms can disrupt Earth's magnetic field, but they can also affect satellite communications.
Another challenge is the disruption of the satellites by so-called "space weather events". These are events where energy and matter are released from the sun into space and hit the earth. These events can damage electronic systems on Earth and also affect satellites.
These issues also need to be considered when using drones, as most drones are controlled using satellite navigation. When satellite communications are disrupted by geomagnetic storms or other events, drones are no longer able to accurately determine their exact position and trajectory.
It is therefore important that our customers keep an eye on the so-called “KP Index”. The KP index is a measure of solar particle radiation in near-Earth space and indicates how strong the disturbances from solar storms or other events are. If the KP index is high, you should be extra careful and possibly reduce the use of satellite navigation systems and drones. The measured “FiX” should also be checked! We are already aware of cases where the coordinates measured by FIX-RTK showed deviations of several decimetres!
Overall, the 25th solar cycle presents some challenges for the use of satellite technology and drones. It is important to keep these challenges in mind and take appropriate measures to minimize interference and ensure the safety of aircraft and other systems.
