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.
StarFire
The system provides <10cm position accuracy (post-
convergence period
1
) when StarFire correction
signals are used.
RTK
The system provides immediate <1cm position
accuracy when UltraRTK
2
correction signals are used
(baseline, <40km,
±1cm +0.5ppm).
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
