Accuracy
When WAAS, EGNOS, MSAS, or GAGAN
(RTCA/DO-229D compliant) SBAS correction signals
are used, the system provides <50cm 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 for contact information regarding
the organizations that implement the
RTCA/DO-229D standard.
The system provides <10cm position accuracy (post-
convergence
2
period) when StarFire™ correction
signals are used.
The system provides instant <0.5cm position
accuracy when Ultra-RTK
1
correction signals are
used (base-line, <40km, 0.5cm +1ppm). Ultra-RTK
requires GPS software version 4.2 or higher.
The system provides instant <1cm position accuracy
when RTK
1
correction signals are used (base-line,
<10km, 1cm +1ppm).
