MAX-7 - Data Sheet1 Functional description1.1 OverviewThe MAX-7 series is the newest family of standalone GPS/GNSS modules from u-blox. With the exceptionalperformance of the u-blox 7 multi-GNSS (GPS, GLONASS, Galileo, QZSS and SBAS) engine, the MAX-7 seriesdelivers high sensitivity and minimal acquisition times in the industry proven MAX form factor.The MAX-7 series provides maximum sensitivity while maintaining low system power. The MAX-7C is optimizedfor cost sensitive applications, the MAX-7Q provides best performance and lowest power consumption, whilethe MAX-7W provides best performance and is optimized for active antennas. The industry-proven MAX formfactor allows easy migration from the previous MAX-6 generation. Sophisticated RF-architecture and interferencesuppression ensure maximum performance even in GPS-hostile environments.The MAX-7 series combines a high level of integration capability with flexible connectivity options in a miniaturepackage. This makes it perfectly suited for industrial applications with strict size and cost requirements. The2MAX-7Q is also halogen free (green) which makes it also perfectly suited for consumer applications. The I Ccompatible DDC interface provides connectivity and enables synergies with u-blox SARA, LEON and LISA wirelessmodules.u-blox 7 modules use GPS/GNSS chips qualified according to AEC-Q100 and are manufactured in ISO/TS 16949certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles –Environmental conditions and testing for electrical and electronic equipment”.1.2 Product featuresFunctional descriptionGPS.G7-HW-12012-AAdvance InformationPage 5 of 24

MAX-7 - Data Sheet1.4 Block diagramFigure 1: MAX-7 block diagram1.5 GNSSu-blox 7 positioning modules are multi-GNSS receivers and can receive and track GPS, GLONASS, GALILEO andQZSS 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 / LEA-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 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.Functional descriptionGPS.G7-HW-12012-AAdvance InformationPage 8 of 24

MAX-7 - Data Sheet1.6 Augmented GPS1.6.1 Assisted GPS (A-GPS)A-GPS improves GPS performance by delivering aiding data to the GPS 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 GPS 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 be stored in the memory of the application processor. Therefore, theservice requires no connectivity at system start-up and enables a position fix within seconds, even when nonetwork is available.1.6.2 AssistNow AutonomousAssistNow Autonomous provides functionality similar to Assisted-GPS without the need for a host or externalnetwork connection. It is an embedded feature available free-of-charge that accelerates GPS positioning bycapitalizing on the periodic nature of GPS satellite orbits. GPS orbit predictions are directly calculated by the GPSreceiver and no external aiding data or connectivity is required. AssistNow Autonomous can be used alone, ortogether with AssistNow Online or AssistNow Offline for increased positioning speed and accuracy.For more details see the u-blox 7 Receiver Description Including Protocol Specification [2].1.6.3 Satellite-Based Augmentation System (SBAS)u-blox 7 positioning modules support SBAS. These systems supplement GPS data with additional regional orwide area GPS augmentation data. The system broadcasts augmentation data via satellite which can be used byGPS receivers to improve the resulting GPS precision. SBAS satellites can be used as additional satellites forranging (navigation), further enhancing precision. The following SBAS are supported with u-blox 7: WAAS,EGNOS and MSAS.For more details see the u-blox 7 Receiver Description Including Protocol Specification [2]1.7 EXTINT: External interruptEXTINT is an external interrupt pin with fixed input voltage thresholds with respect to VCC IO. It can be used forControl of the receiver or for Aiding.For more information about how to implement and configure these features see the u-blox 7 ReceiverDescription including Protocol Specification [2] and the MAX-7 / NEO-7 / LEA-7 Hardware Integration Manual [1].1.7.1 Pin ControlThe pin control feature allows overriding the automatic active/inactive cycle of Power Save Mode. The state ofthe receiver can be controlled through the EXTINT pin.The receiver can also be turned off and sent into Backup Mode using EXTINT when Power Save Mode is notactive.Functional descriptionGPS.G7-HW-12012-AAdvance InformationPage 9 of 24

MAX-7 - Data Sheet1.7.2 AidingThe EXTINT pin can be used to supply time or frequency aiding data to the receiver.For time aiding the time can be supplied using hardware time synchronization where an accurate time pulse isconnected to the EXTINT pin.Frequency aiding can be implemented by connecting a periodic rectangular signal with a frequency up to 500kHz and arbitrary duty cycle (low/high phase duration must not be shorter than 50 ns) to the EXTINT pin, andproviding the applied frequency value to the receiver using UBX messages.1.8 TIMEPULSEA configurable time pul
