NEO-8Q - Data Sheet1 Functional description1.1OverviewThe NEO-8Q standard precision GNSS module is built on the reliable performance of the u-blox 8 GNSS engine,which receives GPS, GLONASS, QZSS and SBAS signals. The NEO-8Q delivers high sensitivity and minimalacquisition times in the industry proven NEO form factor.The NEO-8Q module features low power consumption and supports advanced Power Save Modes. It alsoprovides message integrity protection, geofencing, spoofing detection, and odometer functionalities.The NEO-8Q module is an economical choice for best performance and easier RF integration. For RF optimizationthe NEO-8Q module features an additional front-end LNA for easier antenna integration and a front-end SAWfilter for increased jamming immunity. The industry proven NEO form factor allows easy migration from previousNEO generations. Sophisticated RF-architecture and interference suppression ensure maximum performanceeven in GNSS-hostile environments.The NEO-8Q module combines a high level of robustness and integration capability with flexible connectivityoptions. The DDC (I2C compliant) interface provides connectivity and enables synergies with most u‑blox cellularmodules.The NEO-8Q module uses a u-blox 8 GNSS chip, qualified according to AEC-Q100 and manufactured in ISO/TS16949 certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles –Environmental conditions and testing for electrical and electronic equipment”.The u-blox NEO-8Q module can also benefit from the u-blox AssistNow assistance service. The Online serviceprovides GNSS broadcast parameters, e.g. ephemeris, almanac data plus time to reduce the receiver’s time tofirst fix significantly and improve acquisition sensitivity. The extended validity of AssistNow Offline data (up to 35days) and AssistNow Autonomous data (up to 3 days) provide faster acquisition after a long off time.See section 1.6 for more information concerning the NEO-8Q related AssistNow Assistance.1.2Product featuresUBX-15031086 - R03Production InformationFunctional descriptionPage 5 of 25

NEO-8Q - Data Sheet1.4Block diagramFigure 1: NEO-8Q block diagram1.5Supported GNSS ConstellationsThe NEO-8Q module is a single GNSS receiver, which can receive and track either GPS or GLONASS signals. Bydefault the receiver is configured for GPS, including SBAS and QZSS reception.The augmentation systems: SBAS and QZSS can be enabled only if GPS operation is configured.1.5.1 GPSThe NEO-8Q module is designed to receive and track the L1C/A signals provided at 1575.42 MHz by the GlobalPositioning System (GPS). The NEO-8Q module can receive and process GPS concurrently with QZSS and SBASsignals.1.5.2 GLONASSThe NEO-8Q module can receive and process the GLONASS satellite system as an alternative to the GPS. Theu-blox NEO-8Q module is designed to receive and track the L1OF signals GLONASS provides at 1602 MHz k*562.5 kHz, where k is the satellite’s frequency channel number (k –7,., 5, 6). The ability to processGLONASS L1OF satellite signals allows design of GLONASS receivers where required by regulations.To take advantage of GPS and GLONASS, dedicated hardware preparation must be made during the design-inphase. See the NEO-8Q / NEO-M8 Hardware Integration Manual [1] for u-blox design recommendations.1.6Assisted GNSS (A-GNSS)Supply of GNSS receiver assistance information, such as ephemeris, almanac, rough user position and time, willreduce the time to first fix significantly and improve acquisition sensitivity. All u-blox G8020 based productssupport the u-blox AssistNow Online and AssistNow Offline A-GNSS services, support AssistNow Autonomous,and are OMA SUPL compliant.1.6.1 AssistNowTM OnlineWith AssistNow Online, an Internet connected host downloads assistance data from the u-blox AssistNow Onlineservice to the receiver at system start-up. The Multi-GNSS Assistance (MGA) service is an HTTP protocol basednetwork operator independent service.Supplying assistance information, such as ephemeris, almanac, a rough last position and time, can reduce thetime to first fix significantly and improve acquisition sensitivity.UBX-15031086 - R03Production InformationFunctional descriptionPage 7 of 25

NEO-8Q - Data SheetThe AssistNow Online service provides data for GPS, GLONASS and QZSS.1.6.2 AssistNowTM OfflineWith AssistNow Offline service, users can download long-term orbit data over the Internet at their convenience.The orbit data can be stored in the memory of the application processor for subsequent down-load to theNEO-8Q module. Thus the function enables a position fix within seconds, even when no network is available.AssistNow Offline offers augmentation for up to 35 days.The AssistNow Offline service provides data for GPS and GLONASS.1.6.3 AssistNowTM AutonomousAssistNow Autonomous operation provides aiding information without the need for a host or external networkconnection. Based on previous broadcast satellite ephemeris data downloaded to and stored by the GNSSreceiver, AssistNow Autonomous automatically generates accurate predictions of satellite orbital data(“AssistNow Autonomous data”) that is usable for future GNSS position fixes. The concept capitalizes on theperiodic nature of GNSS satellite orbits by capturing strategic ephemeris data at specific times of the day. ForNEO-8Q modules, AssistNow Autonomous can calculate GPS only orbit predictions for up to 3 days.u-blox’ AssistNow Autonomous benefits are: Faster fix in situations where GNSS satellite signals are weak No connectivity required Compatible with AssistNow Online and Offline (can work stand-alone, or in tandem with these services) No integration effort; calculations are done in the background, transparent to the user.For more details on A-GNSS see the u-blox 8 / u-blox M8 Receiver Description Including ProtocolSpecification [2].1.7Augmentation Systems1.7.1 Satellite-Based Augmentation System (SBAS)The u-blox NEO-8Q module supports reception of SBAS broadcast signals. These systems supplement GNSS datawith additional regional or wide area GPS augmentatio

The u-blox NEO-8Q module can also benefit from the u-blox AssistNow assistance service. The Online service provides GNSS broadcast parameters, e.g. ephemeris, almanac data plus time to reduce the receiver’s time to first fix significantly and improve acquisition sensitivity.
