NEO-7 - Data Sheet1.4 Block diagramFigure 1: NEO-7 block diagram1.5 GNSSu-blox 7 positioning modules are GNSS receivers and can singly receive and track GPS, GLONASS, or Galileosignals. QZSS signals may be received concurrently with GPS signals.1.5.1 GPSu-blox 7 receivers are designed to receive and track the L1C/A signals provided at 1575.42 MHz by the GlobalPositioning System (GPS).1.5.2 GLONASSThe Russian GLONASS satellite system is an alternative system to the US-based Global Positioning System (GPS).The u-blox 7 module is capable of receiving and processing GLONASS signals using the same hardware andprovides the lowest power GLONASS functionality in the industry at low cost and with minimal integrationeffort. In order to take advantage of GPS and GLONASS, dedicated hardware preparation must be taken duringthe design-in phase, see the MAX-7 / NEO-7 Hardware Integration Manual [1] for u-blox designrecommendations.The ability to receive and track GLONASS L1OF satellite signals with the same hardware results in an optimizedhardware BOM and allows design of GLONASS ready receivers where required by regulations.Note: GLONASS and GPS signals cannot be received and tracked simultaneously by u-blox 7 modules.1.5.3 GalileoWhen Galileo-L1 signals become available, u-blox 7 flash-based receivers will be capable of receiving andprocessing them via a firmware upgrade. The ability to receive and track Galileo satellite signals will result inhigher coverage, improved reliability and better accuracy.1.5.4 QZSSThe Quasi-Zenith Satellite System (QZSS) is a navigation satellite overlay system for the Pacific region coveringJapan and Australia which transmits additional GPS L1C/A signals. u-blox 7 positioning modules are able toreceive and to track these signals simultaneously with GPS, resulting in better availability, especially under badsignal conditions e.g. in urban canyons.UBX-13003830 - R04Early Production InformationFunctional descriptionPage 8 of 26

NEO-7 - Data Sheet1.6 Augmented GNSSFor more details about augmented GNSS, see the u-blox 7 Receiver Description Including ProtocolSpecification [2].1.6.1 Assisted GNSS (A-GPS)A-GPS improves GNSS performance by delivering aiding data to the GNSS receiver via wireless networks or theInternet. Supplying information such as ephemeris, almanac, approximate last position, time and satellite statusand an optional time synchronization signal significantly reduces Time to First Fix (TTFF) and improves acquisitionsensitivity.AssistNow Online and AssistNow Offline are u-blox’ end-to-end A-GPS services for devices with or withoutnetwork connectivity. AssistNow Online and AssistNow Offline can either be used alone or in combination. Theyare very easy to implement, require no additional hardware, and generate virtually no CPU load. All u-blox 7modules support u-blox’ AssistNow Online, AssistNow Offline and AssistNow Autonomous A-GPS services, andare OMA SUPL compliant.AssistNow OnlineWith AssistNow Online, an internet-connected GNSS device downloads assistance data from u-blox’ AssistNowOnline Service at system start-up. AssistNow Online is network operator independent and globally available.u-blox only sends ephemeris data for those satellites currently visible to the device requesting the data, thusminimizing the amount of data transferred.AssistNow OfflineWith AssistNow Offline, users download u-blox’ Differential Almanac Correction Data from the Internet at theirconvenience. The correction data can either be stored in the GNSS receiver’s Flash memory (available on NEO-7Nonly) or in the memory of the application processor. Therefore, the service requires no connectivity at systemstart-up and enables a position fix within seconds, even when no network is available.1.6.2 AssistNow AutonomousAssistNow Autonomous provides functionality similar to Assisted-GNSS without the need for a host or externalnetwork connection. It is an embedded feature available free-of-charge that accelerates GNSS positioning bycapitalizing on the periodic nature of GNSS satellite orbits. GNSS orbit predictions are directly calculated by theGNSS receiver and no external aiding data or connectivity is required. AssistNow Autonomous can be usedalone, or together with AssistNow Online or AssistNow Offline for increased positioning speed and accuracy.1.6.3 Satellite-Based Augmentation System (SBAS)u-blox 7 positioning modules support SBAS. These systems supplement GNSS data with additional regional orwide area GNSS augmentation data. The system broadcasts augmentation data via satellite which can be usedby GNSS receivers to improve the resulting GNSS precision. SBAS satellite
