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
