VersaLogic has released an industrial temperature GPS module that provides access to multiple satellite systems. It offers higher accuracy than previous models, for both location and timing data, the company said. Its multi-channel capability also allows better accuracy and coverage in difficult environments such as cityscape and building canyons. “The need for enhanced accuracy and precision timing data is growing in embedded computing. The G3 has time pulse accuracy that is less than 20ns when outdoors and 0.5 seconds indoors,” said Kerry Howell, VersaLogic product manager. “When combined with its ability to use multiple satellite systems simultaneously, the G3 becomes a very valuable positioning tool.” The advanced GPS receiver provides two simultaneous receiver paths with 72-channel operation for stable satellite tracking, as well as aided startup for fast initial signal acquisition. Increased coverage is provided by support for GPS, GLONASS, Galileo and BeiDou systems. In addition to positioning and navigation applications, GPS/GNSS signals are widely used as precision time or frequency references for remote or distributed wireless communication, industrial, financial and power-distribution equipment. The G3’s extremely small Mini PCIe format allows it to be added to a system with little impact to the overall size of the system. The G3 is compatible with a variety of popular x86 operating systems including Windows, Windows Embedded and Linux using standard software drivers. The G3 is designed and tested for industrial temperature (-40 degrees to +85 degrees Celsius) operation and meets MIL-STD-202G specifications to withstand high impact and vibration. It is RoHS compliant, and includes VersaLogic’s 5+ year production life guarantee. It is customizable, even in low OEM quantities. Customization options include conformal coating, revision locks, custom labeling, customized testing and screening and more.
