Fig. 3. The exterior of the receiver NAVIA GNSS - KL 3333 top and bottom view (not in scale 1:1). The receiver of KL3333 is based on a modern specialized chipset of MT 3333, representing the family of so-called "systems on a chip", manufactured by Mediatek of the world leader in the production of chips for navigation and multimedia systems. Receiver possesses high sensitivity; low power consumption and low start time. The receiver has 99 channel for acquisition (capture) and 33 channels to track the satellite signals that allows simultaneous search of satellite signals groups of GLONASS and GPS. The receiver lets you apply for a primary search of satellite signals specially prepared 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. Specific information can be prepared by external sources (and transferred to the receiver through the communication channels), and independently 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 suppression that allows it to operate in a difficult jamming environment. The operation of the receiver is carried out by means of special NMEA-like commands. The receiver is equipped with a serial port of the UART. To learn more about the operation of the receiver of KL3333 may meet the "KL3333 demo board". KL3333 demo board is a complete analogue of the GPS navigation equipment of NAVIA GNSS KL 3333 shown in Figure 1. Description of the board is provided in the "demo 7

Navigation device (receiver) NAVIA GNSS - KL 3333 Operation manual 2.0 Typical connection of the receiver KL3333

Fig. 7. Typical receiver KL3333 circuit with NMEA data transferring by the UART. Figure 7 shows a typical circuit of the receiver KL3333 with NMEA data via UART. The power supply Vcc = 2.8...4.2 V connected to pad 8 (V _ IN). The circuit is designated +3.3V main on the wiring diagram. The backup battery voltage in the range of V bat = 2.0…4.2 V should be applied to the contact pad 6 (V_RTC). The circuit is designated + Vbat RTC on the wiring diagram. It is recommended to maintain a continuous Vbat for the operation of the internal clock and memory module. An active or passive antenna is connected to pin 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 microstrip line with impedance of 50 Ohms. Pins 10 and 12 (RF GND) of the receiver is a high-frequency "ground" circuit concerning pin 11 (in the scheme conventionally indicated by the symbol "hatched" of the earth). The antenna power is suppied through the receiver. In the case of an active antenna the main power supply should provide appropriate 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 output 9 should not be connected to any circuit. The output signal is provided as a sequence of NMEA with the serial port UART (pad 2 is Tx signal, pad 3 is the Rx signal). NMEA messages are present at this port NMEA messages by the factory default. These signals are designated in the diagram UART Tx NMEA Out and UART Rx NMEA In respectively. Setting the baud rate of the serial port UART, choice the satellites groups from GLONASS, GLONASS / GPS or GPS, and other settings are made by the special NMEA-like messages. The timestamp signal PPS put into contact 4. This signal can be used for consumer equipment for the exact binding instrument time to standard UTC time. This signal is designated the output 1PPS Out in the wiring diagram. The general GND circuit (pin 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. 15

Navigation device (receiver) NAVIA GNSS - KL 3333 Operation manual 2.0 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 decoupling capacitor should be placed in the interruption of the microstrip line when the receiver signal source has a low DC output impedance. Otherwise it’s possible current overloading of the signal source and / or overheating of the receiver that can result in a shorter lifespan. Note. The receivers KL3333 with data code (the first three digits of the serial number) equal 503 do not guarantee the proper work of PPS.

Navigation device (receiver) NAVIA GNSS - KL 3333 Operation manual 2.0 Installation The receivers NAVIA GNSS - KL 3333 developed as products intended for installation on board the target device (OEM product). The receiver is designed for installation as components of both the automated assembly lines, and for manual mounting and soldering both leaded and lead-free solder paste and/or solders. In the manual installation must be carried out using a grounded soldering iron with tip heated to a temperature no higher than 240 °C. The duration of contact of the receiver terminal should not exceed 3 seconds. The interval between adjacent terminals must be at least 2 seconds between repeated rations to the same conclusion - at least 30 seconds. There is the temperature profile in the case of using lead-free solder pastes during automated installation in Fig. 16. The cooling rate should not exceed 3 ° C per second. Schedule thermoprofile in the case of leaded pastes will be similar in appearance, but to select the temperature and time of each stage should be guided by the documentation of manufacturers for the respective pastes. With bilateral mounting the receiver board must be installed on the other side, which is mounted and soldered in the final pass through the reflow oven, as otherwise the metal screens mounted on the receiver board can break away from the soldering and fall inside the oven.

Fig. 16. The temperature profile for soldering the receivers using leaded-free pastes. When dismantling (desoldering) the receivers from the final product PCB are not allowed to heat them to a temperature exceeding 250 °C. Withal, residence time at temperatures above 230 °C should not exceed 40 seconds. In case of overheating, operation dismantled receivers can be broken. Products dismantled with clear signs of overheating and/or mechanical damage cannot be repaired or replaced under warranty. Also, do not be repaired or replaced under warranty dismantled units whose condition does not allow for analysis of their performance (peel of tracks or pads, offset of screen or components, excess solder on the pads and/or terminals do not allow to insert the product in the test equipment). 21

Navigation device (receiver) NAVIA GNSS - KL 3333 Operation manual 2.0 ESD protection GPS navigation device - KL3333 in the form of boards, and as a navigational device's reception (receiver) NAVIA GNSS - KL3333 products are sensitive to electrostatic discharge. Before using the product you should carefully review the requirements for protection against electrostatic discharge! Navigating equipment and receivers NAVIA GNSS - KL3333 equipped with protection circuits against electrostatic discharges, but non-compliance with the requirements for working with ESD -sensitive products can be generated voltage exceeds the capacity of the protective circuits. It should be borne in mind that the voltage of static electricity depends strongly on the relative humidity (% RH), and materials with which the worker contacts. Approximate values of static electricity generated • The voltage 10-25% RH 65-90% RH • Stroke the floor covered - Vinyl tile 6,000 V 100 V - Carpets or carpeting 35,000 V 1,500 V - Conventional linoleum 12,000 V 250 V - Antistatic linoleum 100 V (max) 20 V (max) • An employee at the table - Standard covers 6000 V 100 V - Antistatic coating 50 V (max) 10 V (max) • A chair with nylon seat 18,000 V 1,500 V • Plastic bag taken from the table 20,000 V 1,200 V Red marked voltage values exceed the capabilities of ESD protection products on the air breakdown on the screen of the receiver, brown - for other conclusions. If there is no galvanic contact between the local ground (for example, the surface of the desktop, instrumentation, etc.) and circuit ground (GND) of PCB with mounted receiver, the first action in the work with the board to be providing such contact. It is forbidden to use the receivers with ungrounded equipment and/or devices. Before connecting the antenna to the receiver should ensure that there is the connection of the grounding terminal of the antenna to the board terminal device and/or receiver. That is unacceptable to use interface, which is possible by contacting the first signal terminal (central core) and then through the ground terminal (shield), for example, type connectors F. It is recommended that the use of types of connectors SMA, MMCX, and the like. Touching antenna input should avoid contact with any charged product (e.g., a ceramic antenna has a capacitance of about 50…100 pF, coaxial cable has a capacitance 50 ... 100 pF/ m, a soldering iron may have a capacity of up to 10nF, etc.). Also you should be careful in contact with materials which can generate and/or store charge. Very good results in the fight against a static electric charge enables the use of a grounded wrist equipment (mats on the desktop, grounding straps, anti-static gloves, anti-static flooring, shoes) and using in the workroom air ionizer, especially in winter. At any stage of transportation, storage, warehouse for processing, installation, operation, dismantling and other works with the receiver should be taken appropriate measures to protect against electrostatic discharge (ESD protection).
