Electrical Specifications3.1. Absolute Maximum RatingsAbsolute Maximum Ratings are stress ratings only.Stresses exceeding Absolute Maximum Ratings may damage the device.Table 3-1: Absolute maximum ratings3.2. Recommended Operating ConditionsFunctional operation above the Recommended Operating Conditions is not implied.Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.Table 3-2: Operating conditionsNote:1. Operation below -200C to -400C and above +700C to +850C is accepted, but TTFF may increase4. Performance4.1. Acquisition timesTTFF (Time To First Fix) – is the period of time from GPS power-up till position estimation. Hot StartA hot start results from software reset after a period of continuous navigation or a return from a short idle period that was preceded by a period of continuous navigation.In this state, all of the critical data (position, velocity, time, and satellite ephemeris) is valid to the specified accuracy and available in SRAM.Warm StartA warm start typically results from user-supplied position and time initialization data or continuous RTC operation with an accurate last known position available in memory. In this state, position and time data are present and valid, but ephemeris data validity has expired. Cold StartA cold start acquisition results when either position or time data is unknown. Almanac information is used to identify previously healthy satellites.Aided StartAiding is a method of effectively reducing the TTFF by making every start Hot or Warm.Table 4-1: Acquisition times4.2.

Power ManagementThe ORG13XX series modules have three main operating modes which are controlled by internal state-machine.These modes provide different levels of power and performance.5.1. Normal ModeIn Normal Mode the ORG13XX series are fully powered and will automatically acquire and trackGPS satellites.5.2. Power Saving ModesAdaptive Trickle Power TMAdaptive Trickle Power (ATP) is best suited for applications that require navigation solutions at afixed rate as well as low power consumption and an ability to track weak signals.In ATP mode the ORG13XX series module is intelligently cycled between three states to optimizelow power operation:Full Power StateThis is the initial state of the ORG13XX series module.The module stays in full power until a position solution is made and estimated to be reliable.During the acquisition mode, processing is more intense, thus consuming more power.CPU Only StateThis is the state when the RF and DSP sections are partially powered off.The state is entered when the satellites measurements have been acquired but thenavigation solution still needs to be computed.Standby StateThis is the state when the RF and DSP sections are completely powered off and baseband clock is stopped.Figure 5-1: ATP timingPush-to-Fix TMPush-to-Fix (PTF) is best suited for applications that require infrequent navigation solutions, optimizing battery life time.In PTF mode the ORG13XX series module is mostly in Hibernate Mode, waked up for Ephemeris and Almanac refresh in fixed periods of time. The PTF period is 30 minutes by default but can be anywhere between 10 seconds and 2 hours. When the PTF mode is enabled the receiver well stay on full power until the good navigation solution is computed.Figure 5-2: PTF timingHibernate StateIn this state the RF, DSP and baseband sections are completely powered off leaving only the RTC and Battery-backed RAM running. When the application needs a position report it can toggle the ON_OFF pin to wake up the module. In this case, a new PTF cycle with default settings begins.6. Interface6.1. Pin AssignmentTable 6-1: ORG13XX series pin-out6.2. ConnectivityPower supplyThe ORG13XX series module requires only one power supply V CC, which can be supplied directly from a battery since the module has internal regulators.It is recommended to keep the power supply on all the time in order to maintain the non-volatile RTC and RAM active for fastest possible TTFF. When the V CC is powered off settings are reset to factory default and the receiver performs Cold Start on next power up.Power supply current varies according to the processor load and satellite acquisition.V CC range is 3.3 to 5.5V DC.Typical I CC current is 30mA during acquisition. Peak I CC current is 50 mA.Typical I CC current in Hibernate state is 30µA.Voltage ripple below 300mV PP allowed for frequency under 10KHz.Voltage ripple below 30mV PP allowed for frequency between 10KHz and 100KHz.Voltage ripple below 10mV PP allowed for frequency between 100KHz and 1MHz.Voltage ripple below 3mV PP allowed for frequency above 1MHz.High voltage ripple may compromise the ORG13XX series module performance.In case of powering the ORG13XX from switching mode (DC-DC) power source carefully follow manufacturer’s application note and apply passive low pass filtering.GroundSingle Ground pin should be connected to main Ground with shortest possible trace or via.ON OFF Control InputThe ON_OFF control input can be used to switch the receiver between Normal or Hibernatemodes and also to generate interrupt in Push-to-Fix operation.The ON_OFF interrupt is generated by a low-high-low toggle, which should be longer than 62µs and less than 1s (100ms pulse length recommended).ON_OFF interrupts with less than 1 sec intervals are not recommended. Multiple switch bounce pulses are recommended to be filtered out.Input level is 3.3V compatible.Figure 6-1: ON_OFF timingnRESET InputThe Power-on-Reset (POR) is generated internally in the ORG13XX series module.Additionally, manual reset option is available through nRESET pin.Resetting the ORG13XX clears the RTC block and configuration settings become default.nRESET pin is active low and has internal pull-up resistor.nRESET signal should be applied for at least 1µs.COMM_SELThe ORG13XX is able to communicate via UART or SPI interface.UART is default communication interface.To select SPI communication 0Ω resistor to system Ground should be applied on this pin.Do not connect if SPI communication is not used.UARTThe device supports full duplex 8-N-1 UART communication without flow control.The default protocol is NMEA.The default configuration for baud rates and respective protocols can be changed by commands via NMEA or SiRF binary protocols.I/O levels in the serial port are CMOS 1.8V/2.5V/3.3V compatible.I/O levels are defined by applying appropriate voltage to V IO-EXT pin.Do not connect if UART communication is not used.SPIThe Host Interface SPI is a slave mode SPI that can be used as an alternative to the UART interface. The four primary pins are SDI, SDO, nSE, SCK.I/O levels are 1.8V compatible.Do not connect if SPI communication is not used.SCK clock frequency must not be higher than 48fo/7 (= 7 MHz approximately).The primary Host Interface SPI features are:∙TX and RX each have independent 1024 byte FIFO buffers.∙RX and TX have independent, software specified two byte idle patterns.∙TX FIFO is disabled when empty and transmits its idle pattern until re-enabled.∙RX FIFO detects a software specified number of idle pattern repeats and then disables FIFO input until the idle pattern is broken.∙FIFO buffers can generate an interrupt at any fill level.∙SPI detects synchronization errors and can be reset by software.The HSPI performs bit-by-bit transmitting and receiving at the same time whenever nSE is asserted and SCK is active.Receive operations do not require an enable.When the system is first turned on, the master in the host system is able to send a message before software has set up the receiver's idle pattern filter. At the system level, protocols are established to specify how the host platform must verify that the GPS system and host SPI are prepared for operation.In general, the GSC3LT loads a ‘power on’ message to the TX_FIFO to inform the host that operations can begin. The protocol specifies the delay and repeats intervals for host query of the slave SPI for this message. This limits the receive byte volume until idle pattern filters are established.On the receive side, the host is expected to transmit idle pattern when it is querying the transmit buffer, unless it has traffic for the GSC3LT. In this way, the volume is discarded, bytes are kept nearly as low as in the UART application because the hardware does not place most idle pattern bytes in the RX FIFO. Most messaging can be serviced with polling.The FIFO threshold can be placed to detect large messages requiring interrupt driven servicing. On the transmit side, the intent is to fill the FIFO only when it is disabled and empty. In this condition, the driver software loads as many queued up messages as can fit in the FIFO. Then the FIFO is enabled. The host is required to poll messages until idle pattern bytes are detected. At this point the FIFO is empty and disabled, allowing the driver to once again respond to an empty FIFO interrupt and load the FIFO with messages, if any are queued up in buffers.Figure 6-2: SPI timingECLK InputThe ECLK is available optionally for external clock input using SiRFLoc client firmware for A-GPS frequency aiding.

If you find that 9600 cannot work next time, please check if it is changed.EXPECTED RESULTIt requires about 35s to locate (first time).Data printed first is original data.Time: L76X GPS Module output time.ARDUINO EXAMPLESThe development board used here is UNO PLUSHARDWARE CONNECTIONEXPECTED RESULTIt requires about 35s to locate (first time). Open serial monitor and set baud rate to 9600. Data printed first is original data.1.W hy the baud rate doesn’t change after send changing command?- Please check if the current baud rate is correct. If the satellites searched are too much, the module cannot allows the baud rate to be smaller. In this case, you can use SET_NMEA_OUTPUT command to reduce the output data per time and try again.2.Why the locating is not accurate?- The accuracy is influenced by environment. Weather reason: The humidity is every high when raining, which weaken the intensity of the GPS signal. It often raining in summer, therefore, the intensity of phone signals is weak. High building reason: high buildings shelter from satellite, make GPS intensity became weak. Area problem: Suburbs have less satellite coverage, so GPS intensity is weak in these areas. Interference problem: Sometime, signals from satellites will be interrupted by atmosphere ionosphere, buildings, forest, water and son on.3.Why the locating result is different with smart phone?- L76X GPS HAT use satellite locating. Smart phone use AGPS, LBS, WIFI and Bluetooth locating as well except satellite. Smart phone locate much faster. And the multi-satellite system used by smart phone are different with L76X’s4.How to exit from Backup mode?- Module output nothing if it enter Backup mode. You cannot exit from Backup mode even re-power. The only way to exit from Backup mode is that short R6 more than 0.5s。

GPS模块使用手册

GPS模块使用手册一、GPS模块旳几种重要指标1.卫星轨迹全球有24颗GPS卫星沿6条轨道绕地球运营(每4个一组)，GPS接受模块就是靠接受这些卫星来进行定位旳。

但一般在地球旳同一边不会超过12颗卫星，因此一般选择可以跟踪12颗卫星如下旳器件就可以了。

固然，所能跟踪旳卫星数越多，性能越好。

大多数GPS 接受器可以追踪8～12颗卫星。

计算2维坐标至少需要3颗卫星，4颗卫星可以计算3维坐标。

2.并行通道由于最多也许有12颗卫星是可见旳，GPS接受器必须按顺序访问每一颗卫星来获取每颗卫星旳信息，因此市面上旳GPS接受器大多数是12并行通道型旳，这容许它们持续追踪每一颗卫星旳信息。

12通道接受器旳长处涉及迅速冷启动和初始化卫星旳信息，并且在森林地区可以有更好旳接受效果。

一般12通道接受器不需要外置天线，除非是在封闭旳空间，如船舱或车厢中。

3.定位时间定位时间是指重启GPS接受器时，拟定目前位置所需旳时间。

对于12通道接受器，冷启动时旳定位时间一般为3～5 min，热启动时为15～30 s。

4.定位精度一般GPS接受器旳水平位置定位精度在5～10 m内。

5.DGPS功能DGPS是一种固定旳GPS接受器，用于接受卫星旳信号。

DGPS可以精确地计算出理论上卫星信号传送到旳精确时间，然后将它与实际传送时间相比较，并计算出差值。

DGPS将这个差值发送出去，其他GPS接受器就可以运用这个差值得到一种更精确旳位置读数(5～10 m或者更少旳误差)。

许多GPS设备提供商在某些地区设立了DGPS发送机，供客户免费使用，只要客户所购买旳GPS接受器有DGPS功能即可。

6.信号干扰要获得一种较好旳定位信号，GPS接受器必须至少能接受到3～5颗卫星。

如果是在峡谷中或两边高楼林立旳街道上，或者是在茂密旳丛林里，有也许接受不到足够旳卫星，无法定位或者只能得到二维坐标。

同样，如果在一种建筑里面，有也许无法更新位置。

某些GPS 接受器有单独旳天线可以贴在挡风玻璃上，或者将一种外置天线放在车顶上，这有助于接受器收到更多旳卫星信号。
