1 Security
This chapter contains important information for the safe and reliable use of
the GPS receiver. Please read this chapter carefully before starting to use the
GPS receiver.
1.1 General information
The Global Positioning System uses satellite navigation, an entirely new
concept in navigation. GPS has become established in many areas, for
example, in civil aviation or deep-sea shipping. It is making deep inroads in
vehicle manufacturing and before long everyone of us will use it this way or
another.
The GPS system is operated by the government of the United States of
America, which also has sole responsibility for the accuracy and
maintenance of the system. The system is constantly being improved and
may entail modifications effecting the accuracy and performance of the GPS
equipment.
1.2 Restricted use
Certain restrictions on the use of the GPS receiver may have to be observed
on board a plane, in hospitals, public places or government institutions,
laboratories etc. Follow these instructions.
1.3 Children
Do not allow children to play with the GPS receiver. It is not a toy and
children could hurt themselves or others. The GPS receiver consists of many
small parts which can come loose and could be swallowed by small
children. Thoughtless handling can damage the GPS receiver.
1.4 Operation/antenna
Operate the GPS receiver with an antenna connected to it and with no
obstruction between the receiver and the satellite.
Make absolutely sure that the antenna socket or antenna cable is not shorted
as this would render the GPS receiver dysfunctional.
Do not use the receiver with a damaged antenna. Replace a damaged
antenna without delay. Use only a manufacturer-approved antenna. Use only
the supplied or an approved antenna with your GPS receiver. Antennas from
other manufacturers which are not authorized by the supplier can damage
the GPS receiver.
Technical modifications and additions may contravene local radiofrequency emission regulations or invalidate the type approval.
Authorized GPS antennas:

1.5 Electrostatic Discharge (ESD)
The JP7 GPS receiver contains class 1 devices. The following Electrostatic
Discharge (ESD) precautions are recommended:
-
Protective outer garments.
Handle device in ESD safeguarded work area.
Transport device in ESD shielded containers.
Monitor and test all ESD protection equipment.
Treat the JP7 GPS receiver as extremely sensitive to ESD.

2 Safety standards
The GPS receiver meets the safety standards for RF receivers and the
standards and recommendations for the protection of public exposure to RF
electromagnetic energy established by government bodies and professional
organizations, such as directives of the European Community, Directorate
General V in matters of radio frequency electromagnetic energy.

4.1 Receiver Architecture
The JP7 OEM GPS receiver from FALCOM is a new OEM GPS receiver
product that features the SiRFstarII-Low Power chipset. This complete 12
channel, WAAS-enabled GPS receiver provides a vastly superior position
accuracy performance in a much smaller package. The SiRFstarII
architecture builds on the high-performance SiRFstarI core, adding an
acquisition accelerator, differential GPS processor, multipath mitigation
hardware and satellite-tracking engine. The JP7
delivers major
advancements in GPS performance, accuracy, integration, computing
power and flexibility.

4.4.1 Configuration and timing signals
RESET_N (Pin 22)
This pin provides an active-low reset input to the
board. It causes the board to reset and start
searching for satellites. Reset is an optional input
and, if not utilized, it may be left open.
T-MARK (Pin 29)
This pin provides 1 pulse per second output from
the board, which is synchronized to within 1
microsecond of GPS time. The output is a CMOS
level signal.
BOOT_SELECT (Pin 3) Set this Pin to high for programming the flash of
the JP7 (for instance updating to a new firmware
for the JP7 ).
4.4.2
Serial communication signals
The board supports two full duplex serial channels. All four connections are
at CMOS levels. All support variable baud rates and all can be controlled
from the appropriate screens in SiRFdemo software. You can directly
communicate with a PC serial port.
RXA (Pin 4)
This is the main receiving channel and is used to
receive software commands to the board from
SiRFdemo software or from user written software.
RXB (Pin 7)
This is the auxiliary receiving channel and is used
to input differential corrections to the board to
enable DGPS navigation.
TXA (Pin 5)
This is the main transmitting channel and is used to
output navigation and measurement data to
SiRFdemo or user written software.
TXB (Pin 6)
For user’s application.

4.4.3 DC input signals
VCC (Pin 1)
This is the main DC power supply for 3,3 V
powered board JP7 .
V_ANT (Pin 19)
This pin is reserved for an external DC power
supply for active antenna.
This pin is optional and hardware changing is
required upon request.
Note: The GPS receiver JP7
has to be
connected with an active 3 V GPS antenna
(max. current of 25 mA). The antenna voltage is
provided by the internal power management.
4.4.4
General purpose input/output (Pin 8, 23, 24, 25, 26, 27 and 28)
Several I/O’s of the CPU are connected to the hardware interface connector
of the JP7. They are reserved for customer specific applications.
For example:
− For realization a SPI-Bus
− For realization an Antenna-indication.
These pins are not supported by the current GPS firmware.

Figure 8: Typical solder conditions (temperature profile, reflow conditions).
The figure below shows the bottom-side of the JP7 GPS receiver.
The four solderable rectangles on the bottom side of the JP7 are soldering
pads, that ensure a better mechanical stability. The four pads must not be
connected among themselves and not to the Ground.

8 First steps to make it work
Figure 10 :
-
Antenna: The connection to the antenna has to be routed on the PCB.
Use a controlled impedance line to connect RF_IN to the antenna or
antenna connector of your choice.
-
Power: Connect GND pins to ground, and connect Vcc pin to 3.3 V. The
power supply should be capable of delivering a sustained current of at
least 200 mA. A proper RESET signal is internally generated.
-
Serial Interface: Pins RXA, RXB and TXA, TXB are 3.3 V CMOS
compatible. The RX inputs and the TX outputs are 5 V TTL compatible.
If you need different voltage levels, use appropriate level shifters.
E. g. in order to obtain RS232 compatible levels use the 3 V compatible
MAX3232 from Maxim or equivalent. GPS data will be transmitted
through port A, if an active antenna is connected, which has a good view
to sky (No obstacle). You can use port B to feed in DGPS correction
data. Pull-up (100 kΩ) unused RX inputs.
-
Active Antenna Bias Voltage: The output voltage at the antenna cable
can be used to power the bias voltage of the antenna, provided can make
sure that the antenna runs down to 2.7 V bias voltage and the current
does not exceed 20 mA.

VERSION 1.02
Backup Battery It is recommended to connect a backup to VBatt in
order to enable the warm and hot start features of the receivers. The
voltage at this pin can be anywhere between 1.85 V and 3.6 V. If you
don’t intend to use a backup battery, connect this pin to GND or leave it
open. Do not use a super cap for the battery backup supply
(recommended by SiRF).
The quickest way to get first results with the JP7 is to use the JP7
Evaluation board together with the program SiRFdemo.
Figure 11:
JP7 Evaluation board
The Evaluation board contains:
- Evaluation Box
- JP7 sample with soldered antenna cable.
- power supply
- active GPS antenna
- RS232 level shifter
- RS232 cable to your computer.
