Technical Data Declaration (Jan 1997)
The Contractor, NavCom Technology, Inc., hereby
declares that, to the best of its knowledge and belief,
the technical data delivered herewith under
Government contract (and subcontracts, if
appropriate) are complete and accurate and comply
with the requirements of the contract concerning such
technical data.
Global Navigation Satellite System
Global Navigation Satellite Systems (i.e., GPS and
GLONASS) are under the control of the respective
Governmental agencies, and the operation of these
satellites may be changed at any time without
warning.
GPS Selective availability (S/A code) was disabled on
02 May 2000 at 04:05 UTC. The United States
government has stated that present GPS users use
the available signals at their own risk.
The U.S. State Department International Traffic in
Arms Regulations (ITAR) regulations limit the
performance of commercial GNSS products. As a
result, access to satellite measurements and
navigation results will be limited from display and
recordable output when predetermined values of
velocity and altitude are exceeded. These threshold
values are far in excess of the normal and expected
operational parameters of the SF-3040 GNSS
receiver.

GNSS Receiver
(rear view)
The lightweight SF-3040 GNSS receiver delivers
unmatched accuracy to the precise positioning
community. This unique unit is designed to use
NavCom’s StarFire™
Based Augmentation System (SBAS) for decimeterlevel position accuracy (post-convergence
period).The receiver is also capable of RTK, RTCM
(code and phase), and CMR/CMR+ DGPS operating
methods. The operating software supports an
optional internal UHF radio modem. Refer to Chapter
7 for details on the removable radio modem.
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 decimeter level positioning
accuracy without the need to deploy a separate base
station, thus saving time and capital expenditure.

network, a worldwide Satellite
The StarFire license is not included in
the price of the SF-3040.
StarFire position outputs are referenced to the
ITRF2008 datum and to the GRS80 ellipsoid.
The SF-3040 pole-mounted GNSS receiver with
integrated antenna is suitable for use in multiple
outdoor applications where it will be subjected to
continuous operation in dust, water-splash, and rain
(but not complete immersion), temperature variations,
and sunlight/UV radiation (refer to Environmental
Specifications in Appendix A).

The SF-3040 Global Navigation Satellite Systems
(GNSS) receiver delivers superior accuracy to the
precise positioning community. This unique receiver
is designed with a robust and long-term performance
upgrade path to meet changing needs via software
upgrades. Increased functionality does not typically
require the costly purchase of additional hardware.
The SF-3040 software-enabled features, purchased
individually, cover a wide variety of applications.
Software option and subscription not
included in the price of the SF-3040.
The SF-3040 is uniquely suited for real-time
applications in areas such as surveying, precise
positioning, and construction. The receiver delivers
the required millimeter measurement precision and
fast update rates at low data latency. The SF-3040
provides the flexibility to be configured as a base
station or as a rover.
Superior interference suppression (both in-band &
out-band), multipath mitigation, and measurement
accuracy are only a few of the receiver’s
technological advances. The SF-3040 GNSS engine
incorporates several patented innovations advancing
2-53
SF-3040 Product User Guide – Rev. F
the existing GNSS technology to the next generation.
The receiver provides near optimal GPS P-code
recovery, providing a significant signal-to-noise ratio
advantage over competing technologies, among other
benefits.
With appropriate software options, the receiver is
capable of the following:
NavCom’s StarFire Network: A worldwide Satellite
Based Augmentation System (SBAS) for
decimeter level position accuracy (postconvergence period). Refer to Chapter 5 for
detailed information.
RTK: This unique receiver is designed to integrate
easily into real-time kinematic (RTK1), field data
verification, topographical surveys, and a wide
variety of surveying applications. The system
resolves ambiguities at startup or on satellite
reacquisition typically within 2 seconds. The
SF-3040 delivers centimeter level position
accuracy via external RTK1 correction formats.
The receiver is capable of Sapphire GNSS
RTK/UltraRTK™, RTCM 2.3 and 3.0 (code and
phase), RTCM 3.1, types 1001-1012, 1019, 1020,
and 1033 (Network RTK1), and CMR/CMR+ DGPS
operating methods.

Dependent on the bundle: A separate
software option is required. The Network
RTK software option allows the receiver to
generate and receive RTCM 1000-series
messages. The navigation algorithms are
designed to support single-base
correction configurations. Network
adjusted RTK formats are not currently
supported.
Internal and External UHF Radio: The operating
software is also capable of supporting an internal
2-54
SF-3040 Product User Guide – Rev. F
radio modem and an external radio modem. Refer
to Chapter 7 for detailed information.
Signal Reception: The SF-3040 GNSS engine
includes a digital ASIC to handle high speed signal
processing.
StarFire Over IP: The StarFire network is available
over the internet. When a data collection device
with internet access is connected to the SF-3040
with supporting software (i.e. FieldGenius or
SurvCE), an independent StarFire server/caster
can be accessed through four mount points. A
choice of three data delivery rates ensures
maximum reliability.
RapidRecovery: The Rapid Recovery feature
provides a way to more quickly recover from the
loss of StarFire corrected positioning after loss
and recovery of navigation. The receiver starts
using these corrections when the link to the
navigation satellites has been lost, or has
degraded to a specified quality value called Figure
of Merit (FOM) which represents the best-guess
accuracy of the horizontal position. Convergence
time in StarFire mode is virtually eliminated under
certain conditions following a very brief
navigational outage.
NavCom recommends using a FOM value
in the range of 5-10.
This feature is available only on the GPS
portion of the StarFire correction, which
constitutes the larger weighted component
of the correction.
RapidRecovery with QuickStart: This feature
enables Rapid Recovery when an accurately
known ITRF08 position is used to initialize
StarFire navigation. This is typically a position
previously surveyed and converted to ITRF08
2-55
SF-3040 Product User Guide – Rev. F
prior to initialization.
This feature is available for StarFire GNSS
only.
The receiver must have a StarFire Dual
Frequency solution prior to initiating
QuickStart.
RapidRecovery is available only on the GPS
portion of the StarFire correction, which

Performance Upgrade Path
The SF-3040 is designed with a robust and long-term
performance upgrade path to meet changing needs
via software upgrades.
Sixty-six signal channels provide the ability to track
multiple frequencies of satellites in several
constellations simultaneously. This allows for
extended navigation in otherwise adverse conditions
for a single constellation. An additional channel is
dedicated to tracking StarFire signals.
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 publiclyoperated signals. Refer to Related
Standards\Publicly-Operated SBAS Signals
for contact information regarding the
organizations that implement the RTCA/DO229D standard.
The system provides <5cm position accuracy (postconvergence period – refer to “convergence” in the
Glossary) when StarFire™ GNSS correction signals
are used.
The system provides instant <1.0cm position
accuracy when Ultra-RTK correction signals are used
(base-line, <40km, 1cm +0.5ppm).
Dependent on software options
2-57
SF-3040 Product User Guide – Rev. F
After RTK correction signals are received, the
baseline length determines how long it takes to
enter RTK mode. A rover close to the base
enters RTK mode almost immediately. For
longer baselines, it may take a minute or two.

Chapter 3 ................................. Interfacing
This chapter details the SF-3040 GNSS receiver
connectors, LED display, appropriate sources of
electrical power, and how to interface to the
communication ports.
Battery Power
Two supplied removable Lithium-Ion battery packs
(PN 98-214946) provide power. Each of the two
battery packs is designed to last 3.5 hours, 7 hours
with both batteries, on a single charge with all GNSS
channels turned on (discharge time varies based on
environmental conditions and mode of operation).
With only L1, L2 and StarFire channels turned on,
each battery will last 4 hours, 8 hours with both
batteries. The smart battery interface allows the
batteries to be hot-swapped on the fly.
When battery 1 voltage is low, the receiver
automatically switches to battery 2 to provide
continuous power. For more information on the
battery packs, refer to the following:
Chapter 6, Batteries
Chapter 8, Safety Instructions
As long as the input voltage on the
external power connector is >9.0 V, the
power input will be from that connector
and the internal batteries will be in
standby mode. This is automatically
selected in the power input output (PIO)
hardware. If the unit does not have an
external power source and is running on
batteries, if an external power source is
connected, the PIO hardware
automatically switches to the external

Power Input 9, 9 to 30 VDC, 8W, red
power source and the battery switches
to standby mode.
If the voltage on the external power
connector drops below 9.0 V, the PIO
begins to draw some power from the
selected battery and the power draw
from that battery increases until the
external voltage decreases to about
8.3 V. At this point, the selected battery
will be supplying all of the power to the
PIO.
The selected battery is the one with the
lowest measured voltage when the PIO
is powered up or reset. This assures
that the one in standby mode is the
one with the most charge remaining so
that if the selected battery falls below
the threshold and the PIO switches to
the other battery, the user will have the
most time to replace or recharge the
discharged battery.
Electrical Power
A 2-pin LEMO female connector provides electrical
power to the SF-3040. It is located on the bottom of
the SF-3040 (refer to Figure 36). Pin assignments are
given in Table 3.

When the battery pack indicator
changes from green to red, the unit
emits a 1-second warning beep.

When both battery packs are low or not
installed, the unit enters a power-down
warning period. During this period, both
battery LEDs blink red, and the unit
emits a series of 3 warning beeps of 1
second each followed by 10 seconds of
silence. This sequence is repeated 4
times. If either battery is replaced during
the warning period with a charged
battery pack, the new battery pack’s
status changes to green and the powerdown warning ceases. The power-down
warning also ceases if an external power
source is connected at this time.

Batteries are not charged in the unit. If
external power is applied, the battery
LEDs indicate the status of the batteries,
not the status of the external power
source.
Over-temperature Shutdown: The
SF-3040 emits a 5-second warning
beep, and all LEDs turn red to indicate
over- temperature condition and eminent
shutdown. This may be caused by
installed batteries and an internal
temperature exceeding 80°C (typically,
65°C ambient) for 5 seconds or longer.
This action is only to protect the
batteries and will not occur if batteries
are not installed.

Chapter 4 ................................. Installation
This chapter provides guidance on SF-3040 hardware
installation for optimum performance.
GNSS Receiver
The SF-3040 housing has a female 5/8-inch BSW
threaded mount (5/8-11 UNC) with a depth of 16 mm
(0.63 inch). Mount the SF-3040 on a surveyor’s pole,
tripod, mast, or any apparatus that accepts the thread
size.
Do not place the receiver in a
space where it may be exposed to
excessive heat, moisture, or
humidity.
There are no user-serviceable
parts inside the SF-3040 GNSS
receiver. Opening the unit
compromises the environmental
seal and voids the equipment
warranty.
4-92
The SF-3040 is not designed for
use on a moving vehicle. If
damage is sustained due to shock
or vibration while mounted on a
moving vehicle or if damage is
sustained due to shear, the
SF-3040 warranty is invalidated.
The SF-3050 is recommended for
use on a moving vehicle and
provides comparable performance
as it is based on the same GNSS
receiver technology.
SF-3040 Product User Guide – Rev. F
Batteries
Refer to Chapter 6 for detailed information on
charging, installing, and maintaining the SF-3040
GNSS battery packs.
Integrated Antenna
Refer to Appendix B for detailed
specifications on the integrated antenna.
Antenna placement is critical to good system
performance. Avoid antenna shading by buildings,
rooftop structures, foliage, hills/mountains, etc.
Choose a mounting location with obstructions
as low as possible (preferably below the horizon),
where the antenna has a clear view of the sky, to
an elevation angle of 7º if possible. Obstructions
below 15º elevation generally are not a problem,
though this is dependent on satellite availability
for the local region.
Avoid placing the antenna where more than 90º
azimuth of the sky is obstructed. When more than
90º of azimuth is shaded, it is often still possible
for the receiver to navigate, however, poor satellite
geometry (due to satellite shading) will provide
poor positioning results. Even 10º of shading can
have a negative effect on performance, though
this generally is not the case.
Avoid placing the antenna on or near metal or
other electrically reflective surfaces.
Do not paint the antenna enclosure with a
metallic-based paint.
Avoid placing the antenna near electrical motors
(elevator, air conditioner, compressor, etc.)
Do not place the antenna too close to other active
4-93
SF-3040 Product User Guide – Rev. F
antennae. The wavelength of L2 is 0.244m and
L1 is 0.19m. The minimum acceptable separation
between antennae is 1m (39 in), which provides
6dB of isolation. For 10dB of isolation, separate
the GNSS antennae by 2.5m, and for 13dB of
isolation (recommended) separate the antennae
by 5m.
Active antennae (those with LNA’s or amplifiers)
create an electrical field around the antenna.
These radiated emissions can interfere with other
nearby antennae. Multiple GNSS antennae in
close proximity to each other can create multipath
and oscillations between the antennae. These
add to position error or the inability to process the
satellite signals.
Most antennae have better gain when the satellite
is high in elevation. Expect tracking performance
to fade as the satellite lowers in elevation. It is not
unusual to see 10dB difference in antenna gain
(which translates into signal strength) throughout
the entire elevation tracking path.
Map obstructions above the horizon using a
compass and inclinometer. Use satellite prediction
software with a recent satellite almanac to assess
the impact on satellite visibility at that location
(available on NavCom’s web site).
A clear line of sight between the antenna and the
local INMARSAT satellite is required to track the
StarFire™ signal. INMARSAT satellites are geosynchronized 35,768kms above the Equator,
currently at Longitudes 15.5 West, 098 West,
142 West, 025 East, 109 East, and 143.5 East.
An inclination and bearing estimation tool is
available on NavCom’s website to aid in
determining potential obstructions to the StarFire™
signal.

Communication Port Connectivity
Connect the supplied LEMO 6-Pin connector of the
serial cable (PN 96-212169-01) COM 2 of the
SF-3040. Connect the DB9S end to the control
device.
In the Rover, the NMEA port is an output logical port
and may share the data physical port with RTCM,
CMR, or Sapphire GNSS RTK input corrections. In
the Base Station, the NMEA port should not share the
data port with any RTCM, CMR, or Sapphire GNSS
RTK output corrections as many NMEA-compatible
devices are likely to have parsing issues with the nonNMEA data.
Refer to the Sapphire Technical Reference Manual
for the available port configuration settings.

SF-3040 Product User Guide – Rev. F
Auxiliary Communication Module (Internal
UHF radio)
An optional 1-Watt internal, removable UHF radio is
available with the SF-3040. (Refer to Chapter 7 for
detailed information). The operational range of the
1W radio varies with the undulation of the
topography, the density of foliage and man-made
materials (i.e. buildings), the type of antenna
employed (NavCom offers a half-wave antenna), and
the height of the base antenna. A broadcast range of
2km is not uncommon, but will vary greatly based on
the operating environment. If a longer range is
desired, NavCom offers a 35W radio option.
Basics of RTK Surveying
RTK (Real-Time Kinematic) is a GNSS system that
yields very accurate 3D position fixes immediately in
real-time.
The Network RTK software option allows
the receiver to generate and receive
RTCM 1000-series messages. The
navigation algorithms are designed to
support single-base correction
configurations. Network adjusted RTK
formats are not currently supported.
A reference station (base station) transmits its GNSS
position to roving receivers as the base receiver
generates them. The roving receivers use the
reference station readings to differentially correct their
own positions. Accuracies of a few centimeters in all
three dimensions are possible. RTK requires
multi-frequency GNSS receivers and high-speed
radio modems.
4-96
SF-3040 Product User Guide – Rev. F
Proper setup of a reference station minimizes GNSS
errors in the rover. The reference GNSS receiver is
set up at a known surveyed location. With this
position locked in, it transmits its code, clock, and
reference station coordinates information to the
roving receiver(s). The roving receiver(s) use this
information to correct each GNSS measurement
received.
If the receiver will be used or transported above
40,000 ft (12.2 km), it must be located in a
pressurized compartment.
The SF-3040, when configured as a reference
station, can transmit corrections to any number of
roving receivers capable of picking up the radio signal
and decoding one of these correction formats:
NavCom proprietary, RTCM 2.3/3.1 for Network RTK,
CMR, or CMR+. The signal can be received in less
than ideal environments, though some data loss may
occur.
Setup of the reference station receiver above the
roving receivers is recommended to enable
transmission to all rovers in all directions with minimal
obstruction. High- frequency radio signals generally
travel a shorter distance than lower-frequency signals
and do not penetrate obstructions as well over
distance.
Refer to Chapter 8, RTK Setup, in the StarUtil 3000
User Guide for detailed instructions.

SF-3040 Product User Guide – Rev. F
Chapter 5 ............................... Configuration
The SF-3040 has a rich interface and detailed control
language, allowing each unit to be individually
programmed to a specific application.
There are essentially 3 methods available to
configure and control the SF-3040:
1. StarUtil 3000 – This program is a NavComdeveloped utility designed to configure and view
many (but not all) of the SF-3040 functions. In
addition to its setup capabilities, StarUtil 3000 can
capture and log data, upload new software and
licenses to the internal processor, and query and
display various receiver performance functions.
Though it is developed as an Engineering tool, it
has its own place in the commercial market as
well. The program is provided on the SF-3040
Product USB Flash Drive.
2. 3rd party controller – Some manufacturers have
already integrated NavCom’s control features in
their bundled hardware and software solution kits
in a variety of applications including GIS, Machine
Control, Aerial Photogrammetry, Land &
Oceanographic Survey, Agriculture, and Military
products. Information on these applications is
available from the NavCom web site and
customer service.
3. User Program – Users may develop unique
operating programs to control the SF-3040
(potentially in conjunction with other devices or
utilities). To facilitate this effort, NavCom provides
the Sapphire Technical Reference Manual (TRM).
Information on this tool is available from the
NavCom Web site and customer service.
