(1) All the available GNSS signals are processed equally and combined performance in harsh environment.

(2) Accuracy and TTFF specifications may be affected by atmospheric conditions, signal multipath, and satellite geometry. Position accuracy specifications are for horizontal positioning. Vertical error is typically < times horizontal error

(3) Performance values assume minimum of five satellites, following the procedures recommended in the product manual. High multi-path areas, high PDOP values and periods of severe atmospheric conditions may degrade performance.

(4) Steady state value after sufficient convergence time.

(5) Typical values for properly installed antenna on vehicle body.
