LED Indicators
The SBX-4 engine has two surface-mounted LED indicators located on the opposite side of the
board in relation to the header connectors. The red LED is for signaling the power-on status of
the receiver, labeled with “PWR” silk-screening. The green LED is for indicating signal acquisition,
labeled with “LOCK” silk-screening.
When power is applied to the SBX-4, the power LED illuminates and when the SBX-4 achieves
signal acquisition on a valid DGPS beacon, the lock LED illuminates.

Note: In order to maintain backwards hardware compatibility with the SBX-3, it is possible to
power the SBX-4 with 5 V. The serial data output level will track the input voltage when greater
than 3.3 V is supplied. The serial data inputs will be tolerant to voltages up to the level of the
supplied input voltage.
Signal Lock Indicator Pin
Pin 16 of connector J300 may be used to drive an LED or sensor to indicate that the SBX-4 is
locked to a beacon signal and is demodulating RTCM SC-104 data. The maximum current
available from this pin is 5 mA at an input voltage 3.3 V. The output of this signal may be
transistor buffered within your integration if greater current is required.

Reset Pin
Pin 19 of connector J300 may be used to reset the SBX-4. Activating the reset circuit of the SBX4 results in the same effect as cycling the input power to the receiver. The operating configuration
of the receiver before reset is maintained, including operating mode, baud rate, frequency and
MSK rate of the last tuned station.

Antenna Interface
Power may be supplied to the antenna externally through the SBX-4 OEM beacon receiver in one
of two ways:
 Connect Pin 4 of J200 to the antenna power supply (+5 VDC) and connect pin 1 and 3
to ground
 Connect Pin 1 and 2 of SBX-4 connector J300 to the associated power supply (+5 VDC)
and connect pin 1 and 3 of J200 to ground
Pin 4 of connector J200 is internally connected to Pins 1 and 2 of connector J300. Antenna signal
input to the receiver is provided via Pin 2 of J200.
Note: The antenna input voltage is not current limited on the SBX-4 board. If current limiting is
required, the circuitry must be provided within your integration.
Note: External power applied to the SBX-4 for powering the antenna is internally coupled to the
signal input pin (Pin 2 of J300). You do not have to provide this circuitry within your integration.
If you intend to use a 4-pin connector (for example, Panduit CE100F22-4) and a length coaxial
cable to interface the antenna to the SBX-4, follow these instructions:
1. Connect the center conductor of the coaxial cable to Pin 2 of J200.
2. Connect the shield of the coaxial cable to Pin 1 or Pin 3 of J200.
Radio Frequency Immunity and Emissions
When integrating the SBX-4, ensure that complete integration does not emit significant noise
within the 283.5 to 325.0 kHz beacon band. In-band interference incident upon the SBX-4 or its
antenna can influence the reception enough that its quality may be degraded, resulting in a lower
SNR measurement with reduced GPS correction data throughput.
Beacon antennas are designed to pick up any radio frequency energy within the 283.5 to 325.0
kHz beacon band. Both beacon signals and environment noise will be picked up by the antenna
and amplified before going to the receiver. Eliminating the majority of noise within the beacon
band is crucial to achieve optimal system performance.
It is very important to consider the overall performance objectives of the system design with
respect to radio frequency emissions.
Certain nations and industries around the world require positioning and navigation electronics to
achieve certain levels of electromagnetic emissions.

SBX-4 Dual Serial Port Overview
The SBX-4 features two full duplex serial ports (Port 0 and Port 1). Use of the second serial port
is an option as the SBX-4 supports identical functionality as its predecessor, the SBX-3 on Port 0.
The main purpose of the second serial port is to allow the continuous flow of RTCM data from
Port 0 to a GPS receiver while allowing monitoring of SBX-4 performance via NMEA response
messages on Port 1. Separating RTCM differential data from NMEA status data when output via
the same serial port poses software integration challenges and potential GPS RTCM reception
conflicts.
Single Serial Port Operation
Some integration designs using the SBX-4 beacon receiver include a micro-controller between
the beacon and GPS receiver to provide enhanced communication and data parsing capability.
Within this type of integration, it is possible for the micro-controller to command and query the
beacon receiver and to parse NMEA response strings from RTCM data without impeding the
continuous flow of RTCM data to the connected GPS sensor.
To separate NMEA messages from RTCM data output by Port 0 through a parsing routine,
without causing a parity failure of the RTCM, it is necessary to take advantage of the fact that “$”
and “<LF>” are not supported within the RTCM specification, provided there are no bit errors in
the RTCM stream to start with. Therefore, if a “$” is received, then it should be considered as the
beginning of a NMEA sentence and a “<LF>” should be expected within a window of certain
length. If the parsing routine does not receive one, due to an unlikely communication line error,
after a window of a particular number of bits has passed, re-synchronization to the RTCM data
must occur.
Note: If port 1 is not being used, pin 18 should be connected to the input power supply through a
10 Kohm resistor.
Dual Serial Port Operation
Although an integration may be designed with a microprocessor between the SBX-4 and the GPS
receiver to tune and monitor SBX-4 status, the second serial port of the SBX-4 eliminates the
requirement to develop a NMEA message parsing algorithm.
With this type of architecture, the SBX-4’s main serial port may be interfaced to the GPS
receiver’s receive line to provide RTCM correction data. The secondary serial port interfaces to
the microprocessor for NMEA configuration and querying. This ensures that NMEA response
messages do not interrupt the continuous flow of RTCM data to the GPS receiver.

6. When powered for the first time, the SBX-4 will operate in the default ABS mode and
will conduct a Global Search (GS) to identify the highest quality beacon signal.
Following the signal acquisition phase of the GS and when the primary receiver
channel has acquired a beacon, the receiver’s second channel will conduct a
background search.
7. When the SBX-4 receives a valid RMC message on Port 0, it will switch to database
mode.
8. You may tune the receiver to a specific beacon using the $GPMSK Manual Tune
command referred to in Hemisphere GNSS’ Technical Reference Manual.
9. When tuned to a valid beacon, the SBX-4 monitors RTCM SC-104 message lock,
parity check and outputs RTCM corrections through its primary communications port.
The SBX-4 asserts the lock signal on pin 16 of J300 (active high).
10. When input power to the SBX-4 is cycled, or the receiver reset circuit is activated, the
SBX-4 will attempt to reacquire the last station to which it was tuned. In Automatic
mode, the SBX-4 will try to lock to this station for 10 seconds before initiating a fresh
GS to identify valid beacons. If set to Manual mode, the receiver will attempt to lock
to the last known beacon indefinitely, or until commanded to a new frequency and bit
rate. In Database mode, the SBX-4 will try to lock to the closest station using the last
valid position.

Chapter 3: SBX-4 Operation
Introduction
Many marine authorities, such as coast guards, have installed networks of radio beacons that broadcast
DGPS corrections to users of this system. With the increasing utility of these networks for terrestrial
applications, there is an increasing trend towards densifying networks inland.
The SBX-4 is able to operate in manual or automatic tuning mode, or using Database mode which will
select the closest station in compliance with IEC 61108-4 standards. In Database mode, the receiver will
search for the closest station based on its current location and distance to the internal list of station
locations.
This chapter includes information on the following topics:
• Beacon information
• Operating modes
• Evaluating performance
Beacon Information
The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) endeavors
to maintain an accurate listing of DGPS radio beacons worldwide that is available on the Internet from
their home page:
http://www.iala-aism.org/
This listing contains the following information regarding currently operating beacons and potential new
sites:
 Station name
 Frequency
 MSK rate
 Location Transmitting ID
 Reference station ID
 Field Strength
 Operating notes
For detailed information on radio beacon transmissions, please refer to Hemisphere GNSS’ Technical
Reference Manual.
SBX-4 Integrator Guide
Appendix A-Troubleshooting

Operating Modes
The SBX-4 may be operated in Automatic Beacon Search (ABS) mode, Manual Tune or Database mode.
In ABS mode, the receiver will identify and tune to the station providing the strongest DGPS signal using
two receiver channels. In Manual mode, you specify the frequency to which the receiver will tune. In
Manual mode, only the primary receiver channel is used. In Database mode, the receiver will search for
the closest station based on its current location and distance to the internal list of station locations.
Refer to Hemisphere GNSS’ Technical Reference Manual Manual for commands relating to changing the
operating mode and monitoring receiver performance.
Automatic Beacon Search (ABS) Mode
The SBX-4 beacon receiver operates in ABS mode by default, selecting and tuning to the most
appropriate beacon without operator intervention. The SBX-4 uses its two independent channels to
identify and lock to the best DGPS beacon.
ABS mode is ideal for navigation applications over considerable areas with various beacon stations
available, eliminating the need for operator intervention when traveling from one beacon coverage zone
to another.
ABS Global Search
When powered for the first time in ABS mode, the SBX-4 initiates a Global Search (GS), examining each
available DGPS beacon frequency, and recording Signal Strength (SS) measurements in units of decibel
micro volts to the Global Search Table. The receiver uses these measured values to compute an average
SS, noise floor and to sort the frequencies in descending order of SS.
This initial phase of the GS takes approximately 3 to 4 seconds to scan all 84 beacon channels in the
frequency band using both channels. Once scanned, and with SS numbers identified for each beacon
channel, both receiver channels cooperatively examine the frequencies with the highest SS
measurements, above the computed noise floor, to determine the station providing the strongest RTCM
signal.
The receiver's primary channel locks to the first identified DGPS broadcast, while the second channel
continues searching in the background for superior beacon signals. If no signal is available, the SBX-4
will initiate a fresh GS, continuing this cycle until it finds a valid beacon.
The secondary acquisition phase of the GS composes the remainder of the time required to acquire the
beacon signal. The time required to acquire a beacon in ABS mode is dependent upon the signal quality
of DGPS beacons in your area, and their relative strength to other non-DGPS beacon signals in the 283.5
to 325.0 kHz band.
As this frequency range is a navigation band, it is shared with other navigation aides such as nondirectional beacons used for aviation and marine navigation. Depending on the signals available, initial
acquisition make take less than 15 seconds for a strong beacon station, from a cold start or up to a
couple minutes if a beacon site is weak relative to other signals. During the acquisition phase, if bit errors
occur due to a weak DGPS beacon signal or environmental noise occurs, the time to acquire may be
longer.
SBX-4 Integrator Guide
Appendix A-Troubleshooting
Page A2
ABS Background Search
During the Background Search, the second channel examines all frequencies at both the 100 and 200
bps MSK bit rates to identify beacons possessing superior signal quality. If a DGPS broadcast is identified
that exhibits a 2 dB greater signal strength than that of the primary station, the receiver will automatically
switch to this beacon. No loss of lock occurs on the primary station during the background scan process.
If the secondary receiver channel finds a superior station, the main channel is instructed to tune to the
new beacon.
The SBX-4 stores the current primary beacon in memory so that it is available upon subsequent powerup. You may force a new GS at any time using the $PCSI,4<CR><LF> proprietary NMEA 0183 command
defined in Hemisphere GNSS’ Technical Reference Manual.
Manual Mode
In Full Manual Tune mode, you may specify a frequency and bit rate for the receiver to tune to or specify
the frequency only, allowing the SBX-4 to identify the correct MSK bit rate automatically (Partial Manual
Tune mode). Setting manual operation is discussed in Hemisphere GNSS’ Technical Reference Manual,
using the $GPMSK NMEA 0183 command.
Acquisition of a beacon in manual tune mode is dependent upon the data rate of the station. In Full
Manual Tune mode with an MSK rate of 200 bps, signal acquisition should occur within 5 seconds if no
demodulation errors occur. Signal acquisition should occur within 10 seconds for a modulation rate of 100
bps provided that no demodulation errors occur.
Partial Manual Tune mode requires that the SBX-4 identify the correct MSK rate automatically. This
automatic detection could result in signal acquisition rates of up to approximately 15 seconds.
Database Mode
This operating mode has been added to the SBX-4 in order to be compliant with the specification IEC
61108-4 for ship borne DGPS maritime radio beacon receiver equipment. The basic operation is outlined
below.
1. The receiver will determine the 10 closest stations after receiving a valid RMC message on
PORT 0. This list can be accessed using the command $PCSI,3,2.
2. The primary channel tries to tune to the closest available station, using the frequency and
bit rate specified in the station database.
3. The background channel tunes to the frequency of the closest station using an alternate bit
rate.
4. The primary channel retunes to the alternate bit rate if lock is achieved on the background
channel (with acceptable station health and WER).
5. The background channel continually searches for a closer station using the station
database once a lock is achieved on the primary channel.
6. The primary channel will remain tuned to the same station unless one of the following
occurs:

Word error rate (WER) drops below 10%

Station becomes unhealthy or unmonitored

Background channel finds a closer station

Position changes enough to affect station list

Evaluating Performance
The SBX-4 calculates a Signal to Noise Ratio (SNR), measured in dB (Decibels), which indicates the
receiver’s performance. The SNR is height of the signal above the noise floor. The higher the SNR, the
better your beacon receiver is demodulating the signal. By monitoring the SNR, you can determine the
optimum location with respect to beacon reception. The SNR is available in the $CRMSS NMEA message
described in Hemisphere GNSS’ Technical Reference Manual.
The SNR is also a function of the installation, as it may differ between locations, depending on the
amount of local noise at each. The optimum antenna location will be the position where your average
SNR is highest. You should turn on all accessories that you intend to use during normal operation to test
the installation. If noise is affecting performance, try to find a better location with higher SNR.
Table 2-1 describes the general quality of reception as measured by the SNR reading of the SBX-4.
