General information
GPS navigation device consumers of global navigation satellite and a system (GNSS),
GLONASS, GPS, GALILEO NAVIA GNSS - KL 3333 (hereinafter - navigation device) is
designed to measurement of current navigation arameters and definitions based on these data on
the current time and location of the receiver (including geogra hical coordinates, altitude and
velocity).
Navigation equi ment of NAVIA GNSS KL3333 is a PCB equi ed with navigation receiver
KL3333 that is mounted on the board, su lied of matching circuits and connectors for connection
to the user equi ment.
Exterior of the navigation equi ment of NAVIA GNSS KL3333 is shown in Figure 1.
Fig. 1. The exterior of the navigation equi ment of NAVIA GNSS KL3333 (not to scale 1:1).
The basis of the navigation equi ment is the navigation device of KL3333 (hereinafter -
receiver or module) that is designed to calculate the current value of geogra hical coordinates
( osition), the time, velocity (s eed) in real time in both autonomous and differential modes,
forming second timestam and to communicate with external devices over a serial ort
(UART). The rinci le of o eration of the receiver is based on a arallel rece tion and rocessing
of 33 measuring channels of signals from navigation satellites. The receiver uses GLONASS in
the frequency range L1 (T-code), GPS on the frequency L1 (C/A code) and GALILEO at a
frequency of E1. Results of the solution (NT) are given in the format of NMEA messages.
The sticker shows the abbreviated name of the receiver NAVIA GNSS KL3333 – “KL-3333”,
acce ted means of identifying are KL -3333, KL 3333.
The user documentation is recommended to use the full name either of the receiver
NAVIA GNSS - KL 3333, or in abbreviated form KL 3333.
The rest of this documentation for the receiver NAVIA GNSS - KL3333 a lies abbreviation

The receiver of KL3333 is based on a modern s ecialized chi set of MT 3333, re resenting
the family of so-called "systems on a chi ", manufactured by Mediatek of the world leader in the
roduction of chi s for navigation and multimedia systems.
Receiver ossesses high sensitivity; low ower consum tion and low start time.
The receiver has 99 channel for acquisition (ca ture) and 33 channels to track the satellite
signals that allows simultaneous search of satellite signals grou s of GLONASS and GPS.
The receiver lets you a ly for a rimary search of satellite signals s ecially re ared
information stored in the receiver's memory that reduces the time of cold start. Moreover, that it is
essential to make a cold start in a weak signal from satellites. S ecific information can be re ared
by external sources (and transferred to the receiver through the communication channels), and
inde endently by the receiver. In the latter case, it is not required to obtain any additional
information from external sources.
The receiver has a built-in noise su ression that allows it to o erate in a difficult jamming
environment.
The o eration of the receiver is carried out by means of s ecial NMEA-like commands.
The receiver is equi ed with a serial ort of the UART.
To learn more about the o eration of the receiver of KL3333 may meet the "KL3333 demo
board".
KL3333 demo board is a com lete analogue of the GPS navigation equipment of

Typical connection of the receiver KL3333
Fig. 7. Ty ical receiver KL3333 circuit with NMEA data transferring by the UART.
Figure 7 shows a ty ical circuit of the receiver KL3333 with NMEA data via UART.
The ower su ly Vcc = 2.8...4.2 V connected to ad 8 (V _ IN). The circuit is
designated +3.3V main on the wiring diagram.
The backu battery voltage in the range of V
bat
= 2.0…4.2 V should be a lied to the contact
ad 6 (V_RTC). The circuit is designated + V bat RTC on the wiring diagram. It is recommended
to maintain a continuous Vbat for the o eration of the internal clock and memory module.
An active or assive antenna is connected to in 11 (IN _ RF). The antenna connector is
designated J1 on the wiring diagram. A conductor connecting the contact 11 and the receiver
antenna should be made as a microstri line with im edance of 50 Ohms. Pins 10 and 12
(RF GND) of the receiver is a high-frequency "ground" circuit concerning in 11 (in the scheme
conventionally indicated by the symbol "hatched" of the earth). The antenna ower is su ied
through the receiver. In the case of an active antenna the main ower su ly should rovide
a ro riate load characteristics.
Signal / RST (Pin 9) is to restart (reset) the firmware of the receiver. If the user device does
not use this signal, then the out ut 9 should not be connected to any circuit.
The out ut signal is rovided as a sequence of NMEA with the serial ort UART ( ad 2 is
Tx signal, ad 3 is the Rx signal). NMEA messages are resent at this ort NMEA messages by
the factory default. These signals are designated in the diagram UART Tx NMEA Out
and UART Rx NMEA In res ectively.
Setting the baud rate of the serial ort UART, choice the satellites grou s from GLONASS,
GLONASS / GPS or GPS, and other settings are made by the s ecial NMEA-like messages.
The timestam signal PPS ut into contact 4. This signal can be used for consumer
equi ment for the exact binding instrument time to standard UTC time. This signal is
designated the out ut 1PPS Out in the wiring diagram.
The general GND circuit ( in 1) must be connected to general GND circuit GND of the
consumer device that uses the receiver.
GND and RF GND (in the diagram designated "hatched ground") are combined within the
receiver and does not need to have communication with each other outside of the receiver.

Moreover, in order to avoid reducing the quality of the signals from the antenna recommended not
combining these signals on the PCB.
Warning! The serial decou ling ca acitor should be laced in the interru tion of the
microstri line when the receiver signal source has a low DC out ut im edance. Otherwise it’s
ossible current overloading of the signal source and / or overheating of the receiver that can result
in a shorter lifes an.
Note. The receivers KL3333 with data code (the first three digits of the serial number)
equal 503 do not guarantee the ro er work of PPS.

Energy saving modes
The most im ortant feature of navigation modules assembled on the base of chi set of
Mediatek MT3333 is their cost-effectiveness of ower consum tion. So, at the end of 2014
MT3333 chi set remains the most economical and flexible in terms of ower consum tion of all
commercially roduced chi sets. Accordingly, the modules are based on this chi set are leaders
in energy-efficiency.

The receiver works in a differential mode.
Differential mode is for a significant increasing the accuracy of location. This increased
accuracy is achieved by corrections transmitted by SBAS satellites (WAAS, EGNOS, MSAS,
GAGAN):
• turn on the mode of searching of the differential correction satellites:
$ PMTK313,1 * 2E <CR><LF>
• turn on «SBAS» as a source of correction information in the receiver:
$ PMTK301,1 * 2D <CR><LF>
• ensure that the receiver takes into account the correction signal
When the receiver is in differential mode in the $GPGGA message GPSQual field will

Management of the receiver
The o eration of the receiver is carried out both by means of hardware and by means of
s ecial commands to the receiver.
The hardware restart (reset) signal su lied to the s ecial in ut / RST turns the firmware of
the receiver to its original state. At the time of ower on, this command is generated automatically
by the integrated receiver nodes. However the user may instruct the hardware restart at the right
time for him.
There is a s ecial set of NMEA–like commands t o manage the rogram mode and
arameters of the receiver. Commands are in ut to the Rx in. Descri tion of commands is given
in the document "Set NMEA command of KL3333 and SL3333 receiver. df» (current version
available to develo ers u on request).
