System Overview

GPS Sensor System

The SF-2110 GPS
sensor delivers
unmatched accuracy
to the precise
positioning community.
This unique receiver is
designed to use NavCom’s StarFire
is a worldwide Satellite Based Augmentation System
(SBAS) for half meter level position accuracy (post­convergence 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.

9 StarFire

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. Only
SF-2110 sensors with the Bluetooth icon on the front
indicator panel are Bluetooth capable (see Figure 11).

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.

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 publicly­operated 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.

Models

SF-2110M

This model utilizes a compact dual-band antenna
capable of receiving GPS and StarFire signals. This
antenna provides excellent phase center stability in a
small, robust, lightweight format.

The model is ideal for vehicle mounting to suit a wide
variety of machine guidance and control applications
in: GIS (Geographic Information Systems) data
collection, and Nautical Stationkeeping.

It is equipped with additional features allowing
interconnectivity with a variety of antennas and other
instrumentation to suit specific applications and
configurations.

SF-2110R

The SF-2110R is similar to SF-2110M, except that it
includes a separate L-Band antenna
(PN: 82-001018-0001LF) for enhanced StarFire

signal reception in challenging environments such as
high geographic latitude.

 Both the GPS antenna port (ANT 1) and

the StarFire antenna port (ANT 2 -
SF-2110R only) provide 5.0VDC. Care
must be taken to select an appropriately
rated GPS antenna if the standard
NavCom antenna is not used.

Bluetooth

Only SF-2110M and SF-2110R sensors with the
Bluetooth icon on the front indicator panel are
Bluetooth capable (see Figure 11). The Bluetooth
module permits cableless operation between the
sensor and a Bluetooth equipped controller. Wireless
connectivity is provided within a range of 10 meters
(32 feet). The Bluetooth module contains Bluetooth­certified components, and is FCC and CE certified.

 Refer to the StarUtil-2110 User Guide

for instructions to setup Bluetooth
communications via the supplied NavCom
software utility, StarUtil-2110, (see Related
Documents in the fore-matter).

Antennae

Standard

The standard integrated
antenna
(PN: 82-001017­0001LF)
tracks all GPS, WAAS/EGNOS and StarFire signals.
Our compact GPS antenna has excellent tracking
performance and a stable phase center for GPS L1.
The robust housing assembly features a standard
5/8” BSW thread for mounting directly to a surveyor’s
pole, tripod, or mast and is certified to 70,000 feet
(see Specifications for restrictions).

L-band (option – SF-2110R only)

The L-band antenna
(PN: 82-001018-0001LF)
tracks StarFire signals. This
antenna has excellent
tracking performance of
geostationary satellites for
latitudes furthest from the
equator. The robust housing
assembly features a flat
mounting surface with three
mounting holes and a 3m
coaxial cable with TNC
connectors. The L-Band antenna comes with a pipe
mount adapter for one inch diameter pipes (see
Figure 24). The SF-2110R uses the SF-2110M GPS
antenna to receive the GPS and WAAS/EGNOS
signals.

SF-2110 User Guide – Rev. C

Controller

The SF-2110 GPS sensor is designed for use with an
external controller solution connected via one of two
serial ports or Bluetooth.

This may be accomplished using a PC, Tablet PC or,
Personal Digital Assistant (PDA) and a software
program which implements the rich control language
defined for NavCom GPS products. Refer to the
user’s guide of the controller solution for further
information. NavCom lists several application
software solutions on our website:

http://www.navcomtech.com/Support/ApplicationSoftware.cfm

In addition, NavCom provides a Windows™ based
software utility, called StarUtil-2110, with the receiver.

Applications

The rugged and reliable SF-2110 GPS series is
designed for productivity with minimal setup time. The
SF-2110 series is ideal for mounting to suit a variety
of machine guidance and control applications as well
as for use in backpack GIS and mapping applications.
The primary operation mode uses the StarFire
service, and offers half-meter accuracy for immediate
results in the field (post-convergence period); great
for navigation and relocation of existing assets. The
two SBAS channels provide free GPS RTCA/DO­229D compliant corrections (WAAS/EGNOS/MSAS/
GAGAN), which coupled with NavCom’s enhanced
SBAS algorithm typically provide sub-meter real-time
accuracy. The receiver also provides sub-meter
accuracy using RTCM DGPS code corrections from
sources such as USCG beacons (additional
equipment required).

Simply connect the controller solution to an available
port and receive NMEA format position information, or
use a NavCom partner controller solution for
additional configuration and monitoring capabilities.
The SF-2110 GPS sensors meet the needs of a large
number of applications including, but not limited to:

9 Land Survey / GIS
9 Nautical Stationkeeping
9 Asset Location
9 Hydrographic Survey
9 Photogrammetric Survey
9 Machine Control
9 Railway, Ship and Aircraft Precise Location

Unique Features

The SF-2110 GPS sensor has many unique features:

 StarFire

1

The ability to receive NavCom’s unique StarFire
correction service is fully integrated within each unit.
A single set of corrections can be used globally
enabling a user to achieve half-meter level positioning
accuracy without the need to deploy a separate base
station, thus saving time and capital expenditure.

StarFire position outputs are referenced to the
ITRF2005 datum (Apr 08).

 Positioning Flexibility

The SF-2110 is capable of using WAAS, EGNOS,
MSAS, GAGAN (RTCA/DO-229D compliant) code
corrections via two internal Satellite Based
Augmentation System (SBAS) channels. The
SF-2110 automatically configures to use the most
suitable correction source available and changes as
the survey dictates (this feature can be overridden).

 Data Sampling
1Hz std, 5 and 10Hz Optional

GPS L1 raw measurement data is output up to 1Hz in
the standard configuration. An optional upgrade
allows 5 and 10Hz raw measurement data via either
of the two serial ports.

The PVT (Position, Velocity, & Time) data is output at
up to 1Hz in the standard configuration. An optional
upgrade allows 5 and 10Hz position updates for
highly dynamic applications.

Separate Software Option Required

 GPS Performance

The SF-2110 utilizes a precision GPS engine, which
incorporates several patented innovations. The
engine’s industry leading receiver sensitivity provides
more than 50% signal to noise ratio advantage over
competing technologies. This results in improved real
time positioning, proven through independent tests,
when facing various multipath environments.

 Rugged Design

Units have been tested to conform to MIL-STD-810F
for low pressure, solar radiation, rain, humidity, salt­fog, sand, and dust.

The rugged design of the SF-2110 system
components provides protection against the harsh
environments common to areas such as construction
sites, offshore vessels, and mines.
