2.1.2.7 Super-Signal (Super-S) technology
In normal operating conditions, low signal strength (that is, signal attenuation) indicates possible
degradation due to multi-path. The receiver trusts such signals less in order to preserve the
quality of the position solution in poor signal environments. This feature can result in degraded
performance in situations where the signals are attenuated for another reason, for example due
to antenna placement. In this case, the weak signal compensation feature can be used to restore
normal performance. There are three possible modes:
• Disabled: no weak signal compensation is performed
• Automatic: the receiver automatically estimates and compensates for the weak signal
• Configured: the receiver compensates for the weak signal based on a configured value
These modes can be selected using CFG-NAVSPG-SIGATTCOMP. In the case of the "configured"
mode, the user should input the maximum C/N0 observed in a clear-sky environment, excluding any
outliers or unusually high values. Choose the configured value carefully, as it can have a large impact
on the receiver performance.
2.2 Augmentation systems
2.2.1 SBAS
MIA-M10Q is capable of receiving multiple SBAS signals concurrently, even from different SBAS
systems (WAAS, EGNOS, MSAS, etc.). SBAS signals are recommended to be used only for correction
data. SBAS signals can also be used for navigation, however they have low weighting and therefore
only a minor impact on the navigation solution.
For receiving correction data, the MIA-M10Q automatically chooses the best SBAS satellite as its
primary source. It will select only one since the information received from other SBAS satellites is
redundant and could be inconsistent. The selection strategy is determined by the proximity of the
