GPS and GNSS signals are essential for more than positioning. In many commercial, defense, wireless, SATCOM, data center, broadcast, transportation, and infrastructure applications, GPS/GNSS signals provide precise timing, synchronization, frequency reference, and system validation. As networks become more distributed, engineers often need to deliver GPS/GNSS signals far beyond the antenna location. A GPS antenna may

Antenna Remoting Over Fiber for SATCOM, NTN, and Direct-to-Device Applications

Satellite communications are changing quickly. Traditional SATCOM systems are being joined by new low Earth orbit constellations, non-terrestrial networks, direct-to-device connectivity, high-throughput satellites, and hybrid terrestrial/satellite architectures. These networks create new demands for RF infrastructure, antenna placement, signal transport, timing, monitoring, and system flexibility. As SATCOM and NTN systems evolve, engineers face a familiar challenge:
