GNSS Antenna

Reliable signal acquisition for critical infrastructure.

The SEL-9524 is a rugged and reliable antenna designed for GNSS devices for critical infrastructure applications. It was designed, tested, and manufactured to the same standards as other SEL products intended for critical infrastructure. The antenna is IP68-rated, making it suitable for harsh environments. Industry-leading surge immunity allows this antenna to provide superior performance in the presence of lightning and other surge events.

The SEL-9524B receives signals from both GPS and GLONASS satellite constellations for added reliability. Customers can also select the SEL-9524A to receive only GPS signals.

Satellite Signal Acquisition for Satellite-Synchronized Clocks—Pair the SEL-9524 with any satellite-synchronized clock to receive time signals via Global Navigation Satellite Systems (GNSS). With high gain and strong out-of-band rejection, the SEL-9524 provides reliable signal acquisition for any satellite-based time synchronization system.

GPS/GLONASS Support for Satellite Signal Verification—Use the SEL-9524B to receive satellite signals from both GPS and GLONASS satellite constellations. When paired with the SEL-2488, signals from these constellations can be used in concert to detect GPS spoofing attacks. The SEL-9524A is also available for solutions that require GPS only.

Satellite Signal Acquisition for Critical Infrastructure—Apply the SEL-9524 for mission-critical applications that rely on reliable GNSS signal reception. Designed, manufactured, and tested in a facility that serves critical infrastructure, the SEL-9524 is a great fit for any application that depends on GNSS signals.

Best Quality and Performance

  • Take advantage of >40 dB gain and strong out-of-band rejection.
  • Count on reliable performance in the presence of lightning and other surge events. The SEL-9524 has industry-leading surge immunity.

Antenna Diagnostic LED

  • Easily troubleshoot installation and powering issues in the event of cable damage or improper installations. The antenna is equipped with an LED indicator that tells whether the antenna is receiving the appropriate power.

Hardened for Any Environment

  • Trust in the same design and type-testing applied to critical protective relays.
  • Deploy in any environment. The SEL-9524 has a temperature range of –50° to +85°C (–58° to +185°F) and is IP68-rated for weather protection.

The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
