System Overview
GPS Sensor System

sensor delivers

1StarFire™ network, which is a worldw
Satellite Based Augmentation System (SBAS) for ha
meter level position accuracy (post-convergence
period). The receiver is also capable of RTCM code
and DGPS operating methods. The operating
software is also capable of supporting an external
radio modem.
The SF-2110 integrated sensor consists of:
914-channel, L1-frequency, precision GPS
receiver
92-channel WAAS/EGNOS SBAS receiver
91StarFire™ L-Band receiver
There are two models, the SF-2110M and the
SF-2110R. Packaging and performance standards of
the models are the same; the differences lie in the
features, as described later in this chapter.
The system also includes a wide-band antenna with a
built-in LNA and other interconnection accessories
outlined in Table 1, later in this chapter.

Accuracy
The system provides <50cm position accuracy (post-
convergence2period) when StarFire™ correction
signals are used.
WAAS signals are generated and
controlled through the United States
Federal Aviation Administration (FAA).
EGNOS signals are generated and
controlled through the European
Space Agency. System accuracy with
WAAS or EGNOS signals are subject
to the quality and update rate of these
government controlled signals.
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 10Hz1and Position Velocity Time (PVT)
data at programmable rates from <1Hz to
predetermined rates up to 10Hz1through 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.
NCT Binary Proprietary Data
The sensor can output proprietary raw data
