Symmetricom Launches CSAC Product for Precise Timing and Synchronization

After eight years of successful participation in the Defense Advanced Research Projects Agency (DARPA) chip scale atomic clock (CSAC) initiative, Symmetricom, Inc., announced today (January 18, 2011) the general availability of what it says is the world’s smallest, lowest power atomic oscillator: a 16 cubic-centimeter unit weighing less than 35 grams (about 1.25 ounces) and operating on only 115 milliwatts of 3.3 VDC power.

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.
