SF-2110 User Guide – Rev. C
Accuracy
The system provides <50cm position accuracy (post-
convergence
1
period) when StarFire correction
signals on the WAAS grid are used, <1m off the
WAAS grid.
‡
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 <1m position accuracy, when
WAAS, EGNOS, MSAS, or GAGAN (RTCA/DO-229D
compliant) SBAS correction signals are used.
The system provides <1m position accuracy, when
dGPS code correction signals are used.
Features … Applies to All Models
Output Data Rate
Both SF-2110 models can output proprietary raw data
at programmable rates from <1Hz to predetermined
rates up to 10Hz
2
and Position Velocity Time (PVT)
data at programmable rates from <1Hz to
predetermined rates up to 10Hz
2
through two 115kbps
RS-232 serial ports with less than 100ms latency.
<50cm horizontal and <75cm vertical accuracy are
maintained as each output is independently calculated
based on an actual GPS position measurement, as
opposed to an extrapolation/interpolation between
1Hz measurements.
