Trimble has launched IonoGuard, designed to reduce ionospheric disruptions in positioning and navigation by minimizing performance impacts caused by scintillation or signal noise.
Referred to as solar activity, ionospheric disturbances peak every 11 years. The next major disruption, Solar Cycle 25, is expected to peak between 2024 and 2026. Ionospheric activity can directly impact the quality of GNSS signals, leading to the degradation of position accuracy. While this type of disturbance has the greatest impact on high precision GNSS users operating around equatorial and high latitude regions, global disruptions are possible during the height of the solar cycle.
IonoGuard leverages Trimble’s high-precision receiver hardware design and signal tracking, offering improved positioning performance in challenging environments. This will minimize the probability of a complete loss of GNSS signals and improve the signals’ accuracy and integrity.
For Trimble’s geospatial, civil construction and OEM GNSS receivers supporting the ProPoint GNSS positioning engine, IonoGuard is a free downloadable firmware update expected to be available in late 2023 for receivers under warranty.
