STL-2600 Low Earth Orbit Receiver Module

GNSS-independent, low-cost capability to generate UTC nanosecond timing and meters-accurate stationary positioning
STL-2600

The STL-2600 provides a GNSS-independent, low-cost capability to generate UTC nanosecond timing and meters-accurate stationary positioning anywhere in the world while operating in a way that is similar to what a GPS user is accustomed to, but without GPS.

The STL-2600 combines a custom-designed Iridium LEO receiver with a disciplined, high-stability reference oscillator sub-system on a single circuit board. The STL-2600 was designed to be used with the VIAVI Solutions Iridium-based SecureTime LEO Services to provide an accurate, resilient PNT solution.

Highlights

  • NMEA, 10 MHz, 1 PPS outputs
  • OCXO oscillator
  • Jamming and spoofing resistant

  • Alternate Timing Options - STL-2600

    The STL-2600 supports SecureTime LEO services to maintain precise timing when GNSS signals are degraded, unavailable, or intentionally denied.

  • SecureTime LEO

    Satellite-based timing service using a global LEO constellation with service availability in enabled regions. This option uses the altGNSS LEO-STL service with an integrated Viavi receiver, supporting indoor and outdoor antennas. The higher signal power from LEO satellites provides jamming resistance and improved availability in indoor environments.
