The GNSS Disciplined Oscillator (GNSSDO, SKU: GPS‑26289) is a high-performance timing reference system tailored for applications demanding ultra-precise synchronization. At its core is the Septentrio mosaic‑T—a multi‑constellation, multi‑frequency GNSS timing receiver—coupled with a SiTime SiT5358 Super‑TCXO oscillator. This combination delivers exceptional timing stability, achieving 5 ns pulse accuracy and potentially sub‑nanosecond precision when paired with the optional Fugro AtomiChron L‑Band service. Event timing accuracy is within 20 ns, making it ideal for scientific, telecom, or measurement-grade applications.
Built for resilient operation under adverse conditions, the GNSSDO employs AIM+ anti‑spoofing technology to maintain accuracy amid GNSS jamming. It offers robust interfacing options—including Ethernet-over-USB, PoE, microSD storage, configurable 10 MHz output, PPS output, EventA input, and microcontroller-based remote control via a serial console. The rugged aluminum housing is suitable for installation in server racks or weatherproof enclosures.
Powering is highly adaptable: choose from USB‑C, PoE (36–57 V), or DC (9–36 V), and access the module through Ethernet or serial for streamlined system integration. Full documentation, firmware, and schematics are available, with manufacturing based locally in Boulder, Colorado. nioPerfect for labs, telecom systems, or precision research settings, the GNSSDO offers an out-of-the-box solution to ultra-accurate time synchronization and frequency generation.
Subnanosecond Timing Precision: Built around the mosaic‑T GNSS timing receiver, offering 5 ns pulse accuracy, further refined to under 1 ns with an optional AtomiChron L‑Band timing correction service. Event timing is precise to under 20 ns
Robust GNSS Reception & Stability: Supports multi‑constellation, multi‑frequency GNSS (L1/L2/L5) with anti‑spoofing resilience using AIM+ technology, paired with a SiTime SiT5358 Super‑TCXO for superior holdover performance
Versatile Connectivity & Controls: Equipped with USB‑C ports (including Ethernet-over‑USB and Power‑over‑Ethernet support), microSD for local logging, SMA connectors for GNSS antenna, disciplined 10 MHz output (configurable voltage), PPS output, and EventA input—all housed in a durable aluminum enclosure
Flexible Power Options: Can be powered via mosaic‑T USB‑C, ESP32 USB‑C, PoE (36–57 V), or external DC (9–36 V), fitting both lab and field environments
Made and Documented in Boulder, Colorado: Designed and built in the USA, the module includes full documentation, firmware, schematics, and a serial console for remote configuration
Please Note: the mosaic-T firmware (4.14.4) supports RTCM input for RTK Rover positioning. However, RTCM output is not supported. You cannot use the mosaic-T as a RTK Base. The documentation suggests you can, but, sadly, you cannot.
