{"title":"Timing GNSS Breakout - mosaic-T","handle":"sparkfun-timing-gnss-breakout-mosaic-t","url":"/products/sparkfun-timing-gnss-breakout-mosaic-t","description":"Built around the Septentrio mosaic-T module, this breakout is made for demanding timing applications such as high-accuracy time stamping, frequency synchronisation and GPS-disciplined oscillators (GPSDO).The mosaic-T is a multi-band, multi-constellation GNSS receiver with Septentrio AIM+ technology for interference mitigation and anti-spoofing. The board brings out a wide range of the module’s pins in a compact form factor, including a 3.3V logic-level PPS output and an external 10MHz reference input.Configuration and monitoring can be handled through the built-in web interface over USB-C, while a full Command-Line Interface is available for power users and automated setups. Onboard microSD logging can be started, stopped and safely unmounted using the single Log button, with the board appearing as USB mass storage once unmounted.For setup and deeper integration, SparkFun provides supporting documentation including a Hookup Guide, schematic, KiCad files, board dimensions, RxTools software, component datasheets, firmware manual and hardware repository.Features:Extreme Timing Accuracy: Achieve timing precision down to 5ns out of the box, with the potential for sub-nanosecond (<1ns) accuracy using the optional Fugro AtomiChron® L-band service.Disciplined Oscillator Ready: Designed for creating your own GPSDO, with access to RxClkBias data and the external 10MHz reference clock input (EXT REF).Robust Signal Integrity: Septentrio’s advanced AIM+ technology actively mitigates interference and thwarts spoofing attempts.Intuitive Web Interface: The mosaic-T hosts its own web server, accessible via the USB-C connection.Code-Free Data Logging: A single onboard button controls start/stop logging to a microSD card and safely unmounts the card.USB mass storage: Once unmounted, the breakout appears as a USB mass storage device for drag-and-drop log file access.Full CLI Control: Complete Command-Line Interface (CLI) over USB for granular receiver control.Breakout access: Provides access to a wide array of the mosaic-T's pins, similar to a full developer kit, but in a compact form factor.GNSS receiver: mosaic-T GNSS ReceiverConnector: USB-C ConnectorStorage: µSD Card Slot (up to 32GB with FAT32 file system)SMA connector: GPS Antenna (Active, Multi-band)SMA connector: External 10MHz Reference input (min: -14dBm, max: +14dBm)Status LED: Power (Red)Status LED: Pulse-Per-Second (Yellow)Status LED: Data Logging (Green)Status LED: Position/Velocity/Time Solution (Blue)Status LED: RTK Mode (White) (RTK is not supported on the mosaic-T)Button: LogConnector: 6-pin JST GH connector (GHR-06V-S)Connector feature: PolarizedConnector feature: LockingProtection: ESD Protection DiodesSpecifications:I/O Logic-Level: 3.3VExternal 10MHz reference clock input: 50 Ω, 10 MHz signal from −14 dBm to +14 dBmVoltage Range: 3.135 to 3.465VMax current: 500mAChannels: 448 (simultaneous tracking)GPS: L1C/A, L1PY, L2C, L2P, L5GLONASS: L1CA, L2CA, L2P, L3 CDMABeidou: B1I, B1C, B2a, B2b, B2I, B3Galileo: E1, E5a, E5b, E5 AltBoc, E6QZSS: L1C/A, L1 C/B, L2C, L5NavIC: L5SBAS: Egnos, WACold Start: < 45sWarm: < 20sReacquisition: 1sTiming Precision: 5nsTiming Precision with optional subscription: Better than 1ns with an optional subscription to Fugro AtomiChronEvent Accuracy: better than 20nsUpdate Rate: 10HzLatency: < 10msAntenna voltage: 3.3VAntenna max current: 150mAInterface: UART (x4)Interface: USB 2.0 with Ethernet-over-USB and TCP/IP supportInterface: SD CardInterface: GPIO/LEDsA strong choice for timing labs, GNSS integration work, oscillator discipline projects and systems that need reliable PPS and timestamp data.","vendor":"SparkFun","product_type":"GNSS Breakout","in_stock":true,"options":[],"variants":[{"id":15875,"title":"Default Title","sku":"SF-GPS-28731","mpn":"GPS-28731","price":1671.75,"on_sale":false,"in_stock":true,"available_quantity":9}]}
