Enabling next-gen networks.

GNSS Receivers

Protempis offers an existing line up of GNSS timing modules that provides GNSS receiver and PRTC function to be integrated with network equipment. Protempis’s newly added RES720 and ICM720 GNSS receivers provide a dual band multiconstellation secured resilient timing and act as primary reference time clock (PRTC) for precision time distribution in a network. It is the key component to receive and convert the UTC time from GNSS signals. The RES720 GNSS receiver combines PRTC and LNA (low noise amplifier) circuits as an external standalone device or as an internal board or module, and the ICM 720 also offers a programable 10 MHz frequency output.

Additionally, Protempis offers a GNSS receiver integrated with the antenna into an IP67 weatherproof enclosure. Protempis’s Acutime 360 product provides the UTC traceability output in the form of 1PPS and TOD signals to a device requiring UTC time that is up to 1 km from the deployment site.

Protempis also work with customers to develop custom GNSS receiver solutions. Our GNSS custom receivers and Acutime 360 solutions are used by world’s leading networking and Base Station equipment manufacturers. Protempis’s GNSS receivers timing modules make it easier for OEM suppliers to develop their own solutions for 5G, Autonomous Vehicles and Smart Grid environments.

RES 720™ Dual Band GNSS Timing Module

The RES 720 is designed to provide a precise time pulse for the synchronization of 4G/5G base stations, or other systems requiring a precise pulse-per-second (PPS) output. Its 19x19mm surface-mount package makes it ideal for embedding into your host solution. When operating in Over-Determined Timing Mode the accuracy of pulse per second (PPS) is within 5 nanoseconds of GNSS/UTC. Additionally, RES 720 timing module includes many of Protempis’s standard timing features, including Time-Receiver Autonomous Integrity Monitoring (T-RAIM) algorithm, automatic self-survey, and GNSS disciplining of the oscillator to provide an accurate frequency reference.

Highly accurate timing and synchronization is vital to today’s critical network infrastructure efficiently to optimize and improve network performance for enhanced service delivery. Backed by Protempis’s more than 30 years of experience, innovation and long-term commitment to the market, the RES 720 module provides a low-cost, easy to use, highly accurate and reliable GPS timing source for the critical infrastructure in different industry verticals such as 5G X-Haul, smart grid, data center, industrial automation and SATCOM networks as well as calibration services and perimeter monitoring applications.

With integrated Smart GNSS Assurance™ Technology and inherent security features, RES 720 offers an industry leading, value-engineered solution for carrier grade resilient timing products. It is designed to meet the resilient timing requirements mandated by 2020 Executive Order (EO) for positioning, navigation, and timing (PNT) services.


Protempis’s RES 720 module is a dual band (L1 and L5) multi-constellations GNSS timing receiver that provides single RF input for all GNSS bands to simplify host circuitry. Powered by Protempis’s Smart GNSS Assurance™ technology, the timing module offers protection against jamming and hacking of signals with automatic fallback to available GNSS signals (L1 to L5). These capabilities and highly accurate timing service provide operators with the ability to meet stringent timing requirements of critical infrastructure while guarding network synchronization against attacks from hackers. Infrastructure equipment suppliers & solutions providers will benefit by integrating highly accurate clock services to their devices & solutions while enabling secured resilient timing solutions for critical infrastructure.
