Upgrade your firmware for scintillation improvements

We are pleased to share the general release of 7.09.01 and 7.09.02 firmware with PPP accuracy and availability improvements for users operating during ionospheric scintillation events.

Ionospheric scintillation refers to rapid fluctuations in GNSS signal strength and phase due to localized irregularities in the electron density of the ionosphere caused by solar activity. Scintillation is most common along the equator and at high latitudes, however it can occur worldwide. As the Sun enters solar cycle 25, there has been an increase in solar activity, resulting in more intense and frequent scintillation.

To best support our customers through these impacts on GNSS positioning, we’re releasing new firmware: Version 7.09.01 is available for agriculture applications replacing Version 7.08.15, and Version 7.09.02 for all other markets replacing Version 7.09.00. Both versions improve accuracy and operational uptime during scintillation.

The firmware demonstrated 60% PPP accuracy improvements during peak scintillation events, resulting in an operational uptime of >90% for PPP users.*

A vital part of these improvements lies in the combination of multi-constellation and multi-frequency GNSS receivers and TerraStar corrections from NovAtel. With higher signal availability and diversity of positioning data, NovAtel customers will see a marked improvement in positioning accuracy and reliability during scintillation events.

*Improvement in average horizontal error during scintillation period when compared to previous firmware versions. Uptime represents a percentage of a 24-hour period operating in a scintillation-prone region where TerraStar-C PRO solution accuracy is less than five centimeters. Performance varies and is subject to the local environment and the duration and magnitude of scintillation.
