SMART7 Performance Specifications

All specifications subject to GNSS system characteristics.

SMART7 Receiver Performance

Horizontal Position Accuracy1Typical values. All position and velocity RMS values are based on Horizontal position accuracy. Performance specifications are subject to GNSS system characteristics, Signal-in-Space (SIS) operational degradation, ionospheric and tropospheric conditions, satellite geometry, baseline length, multipath effects and the presence of intentional or unintentional interference sources
