Accuracy
SBAS
When WAAS, EGNOS, MSAS, or GAGAN (RTCA/DO-229D compliant) SBAS correction
signals are used, the system provides <30cm 2D position accuracy.

System accuracy with WAAS, EGNOS, MSAS, or GAGAN signals is
subject to the quality and update rate of these publicly operated signals.
Refer to Related Standards/Publicly Operated SBAS Signals in the fore-
matter for contact information regarding the organizations that implement
the RTCA/DO-229D standard.

See the Sapphire Technical Reference Manual (TRACKINGMODE
command) and the StarUtil 3000 User Guide for details on disabling
WAAS, EGNOS, and MSAS.
StarFire
The system provides <5cm position accuracy (post-convergence period)

when StarFire
correction signals are used.
RTK
The system provides immediate < 1 cm position accuracy when UltraRTK

After RTK correction signals are received, the baseline determines how
long it takes to enter RTK mode. A rover close to the base enters RTK
mode almost immediately. For longer baselines, it may take a minute or
two. For L1/G1 RTK, antenna model selection is also a factor in ambiguity
resolution and time required to enter RTK.
