Product Technical Specification AirPrime XM1110 41111059 Rev 1 AirPrime XM1110 Product Technical Specification Important Notice Safety and Hazards Due to the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or receive such data. Do not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive atmospheres may be present, near medical equipment, near life support equipment, or any equipment which may be susceptible to any form of radio interference. In such areas, the Sierra Wireless modem MUST BE POWERED OFF. The Sierra Wireless modem can transmit signals that could interfere with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard systems. Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Sierra Wireless modems may be used at this time. The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of a vehicle. Doing so will detract from the driver or operator's control and operation of that vehicle. In some states and provinces, operating such communications devices while in control of a vehicle is an offence.

it is one of the smallest MediaTek-based modules in the world, for it has an ultra-compact size of 9.0 x 9.5 x 2.1 mm in a QFN Package. This ultra-compact module provides multiple interfaces such as I2C, SPI & UART, and its unique design of SMPS is capable of reducing power consumption to a great extent. The XM1110 is built based on MediaTek's new generation GNSS Chipset MT3333. It supports up to 210 PRN channels with 99 search channels and 33 simultaneous tracking channels. With support of QZSS, SBAS (WAAS, EGNOS, MSAS), QZSS and AGPS, XM1110 can provide even more accurate positioning. Its Tone Active Interference Canceller is capable of removing 12 active noise sources, enabling more flexibility in system design. The XM1110 is integrated along with power managements and many advanced features, including AlwaysLocate™, EASY™, EPO™, PPS sync NMEA and logger. It is ideally suitable for power sensitive devices especially in portable applications.

Multi-tone Active Interference Canceller Navigation systems often integrate with variant applications that are not limited to Wi-Fi, GSM/GPRS, 3G/4G, Bluetooth. Such systems often generate RF harmonics which would influence the GPS reception and performance. The embedded Multi-tone Active Interference Canceller (MTAIC) can reject unwanted RF harmonics of the nearby on-board active components. MTAIC improves the capacity of GPS reception, eliminating the need for hardware integration engineering to make hardware changes. The XM1110 cancels up to 12 independent channels continuous interference wave. 1PPS The XM1110 generates a-pulse-per-second signal (1 PPS). It is an electrical signal which precisely indicates the start of a second with the accuracy of ±20ns RMS (Root Mean Square). The PPS signal is provided through a designated output pin for many external applications. The pulse is not only limited to being active every second but is also allowed to set up the required duration, frequency, and active high/low through a programmable user-defined setting. AGPS for faster TTFF (EPO in flash™) The AGPS (EPO in flash™) provides predicated EPO (Extended Prediction Orbit) data to speed up TTFF (Time To First Fix). This feature is useful when a satellite signal is weak. AGPS can be downloaded from an FTP server via the Internet or Rev 1 Jun.17 8 41111059 Function Description through a wireless network. The GPS engine in the module will apply EPO data to assist with position calculation when navigation information from satellites is insufficient. For more details on EPO, please contact us. EASY™ EASY™ (Embedded Assist System) is for quick positioning/TTFF when information received from the satellites is insufficient (weak signal). When EASY™ is enabled, the GPS engine will automatically calculate and then predict single ephemeris up to three days. The predicted information will be saved into the memory and the GPS engine will then use the saved information for later positioning. Backup power (VBACKUP) is required for EASY™. Figure 1-3: Operation of EASY™ When the module obtains information from GPS satellites, the GPS engine will start to pre-calculate and predict orbits automatically for three days. AlwaysLocate™ In AlwaysLocate™ mode, the on/off time can be adjusted adaptively to achieve balance between positioning accuracy and power consumption depending on environmental or motion conditions. Figure 1-4 gives some insight on power saving in different cases when AlwaysLocate™ mode is enabled. For command detail, please contact Sierra Wireless sales staff. Rev 1 Jun.17 9 41111059 AirPrime XM1110 Product Technical Specification Figure 1-4: AlwaysLocatie LOCUS When LOCUS (Embedded Logger Function) is enabled, the receiver module will become a logger-capable device. It does not need any host or external flash data format such as UTC, latitude, longitude, valid or checksum for GPS data logging. The maximum log duration is up to two days under AlwaysLocate™. PPS sync NMEA Pulse-Per-Second (PPS) VS. NMEA can be used in the time service. The latency range of the beginning of UART Tx is between 465ms~485 ms at the MT3333 platform and behind the rising edge of PPS. The PPS sync NMEA only supports 1Hz NMEA output and baud rate at 115200~14400 bps. For baud rates at 9600 bps and 4800 bps, only the RMC NMEA sentence is supported. If NMEA sentence outputs are supported even at the low baud rate, per-second transmission may exceed the threshold of one second.
