GPS/Galileo/GLONASS timing antenna

PCTEL offers the GPSL1GL-TMG-40N timing reference antenna specifically designed for deployments in congested cell-site applications and able to receive signals from GPS, Galileo, and GLONASS satellites in the 1575.42 ± 10 MHz and 1602-1615 MHz frequency bands. The low-noise, high-gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs. The proprietary quadrifiliar helix design, coupled with multistage filtering improves out-of-band rejection and lower elevation pattern performance.

u-blox Launches GPS Timing Module

u-blox LEA-5T

Swiss GNSS chip manufacturer u-blox has introduced a new precise timing GPS module, the LEA-5T, precise timing at the CTIA Wireless 2008 conference taking place this week in Las Vegas.

Based on the company’s 50-channel, fifth-generation chipset technology, the LEA-5T is intended for such applications as telecom network synchronization, use in WiMAX base stations for home-based broadband networks, and data communication among geographically dispersed systems and devices such as NTP servers.
