Product Technical Specification AirPrime XA1100 41111209 Rev 1 AirPrime XA1100 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. Limitation of Liability The information in this manual is subject to change without notice and does not represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY. Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability arising under or in connection with the Sierra Wireless product, regardless of the number of events, occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the Sierra Wireless product.

It comes with an external antenna interface with automatic antenna detection. It is one of the smallest GPS Antenna modules in the world with an ultra-compact size of 12.5 x 12.5 x 6.8 mm in a QFN Package. This ultra-compact module provides a UART interface and its unique design of SMPS is capable of reducing power consumption to a great extent. The XA1100 is based on Chipset MT3337(E). It supports up to 210 PRN channels with 66 search channels and 22 simultaneous tracking channels. With support of QZSS and AGPS, The XA1100 can provide even more accurate positioning. Its Tone Active Interference Canceller is capable of removing 12 active noise sources and such feature enables more flexibility in system design. The XA1100 is integrated along with power managements and many advanced features, including EASY™, EPO™, PPS sync NMEA, and logger. It is ideally suitable for power-sensitive devices especially for portable applications.

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 XA1100 cancels up to 12 independent channels continuous interference wave. 1PPS The XA1100 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 user-defined PMTK command setting. Rev 1 Jun.17 8 41111209 Function Description AGPS for faster TTFF (HOST) The AGPS (HOST EPO) provides predicated EPO (Extended Prediction Orbit) data to speed up TTFF (Time To First Fix). Users can download EPO data to the GPS engine from an FTP server via the Internet or through a wireless network. The GPS engine of the module will adopt EPO data to assist with position calculation when navigation information from satellites is insufficient due to a weak signal. EASY™ EASY™ (Embedded Assist System) is for quick positioning when information received from the satellites is insufficient. With EASY™ technology, the GPS engine is able to calculate and predict a single ephemeris automatically up to three days when the power is on. It then saves the predicted information into memory so the GPS engine can use this information for positioning later if information received from the satellites is insufficient. This function is useful for TTFF improvement to allow positioning even under weak signal conditions (e.g. in dense urban areas). Backup power (VBACKUP) is required for this feature. Figure 1-3: Operation of EASY™ Figure 1-3 shows that when the GPS device obtains information from GPS satellites, the GPS engine will start to pre-calculate automatically in order to predict orbits for three extended days. Rev 1 Jun.17 9 41111209 AirPrime XA1100 Product Technical Specification 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 170ms~180 ms at the MT3337(E) 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 the NMEA sentence outputs are supported even at the low baud rate, per-second transmission may exceed the threshold of one second.

Use one with equivalent impedance (600Ω at 100MHz; IDC 200mA). 3. Place C0, C1, C2 and C5 bypass-capacitors as close as possible to the module. 4. Damping resistors R1 and R2 can be modified based on system application for EMI.

By following the standards of storage and handling outlined in this document for GNSS modules, the chances of them being damaged during production setup can be reduced. This section will walk you through the basics on how Sierra Wireless packages the modules, to ensure that the modules arrive at their destination without any damages or deterioration for performance quality. Cautionary steps prior to the surface mount process are also included in the cautionary notes. Important: Please read the following sections carefully to avoid possible damage. Important: GPS receiver modules are highly electrostatic-sensitive devices. Without ESD protections or without proper handling may lead to permanent damage to the modules.
