Trimble introduced several antenna and receivers that track GPS L2C and L5 GPS signals, as well as GLONASS satellites. MS990 Smart Antenna, for use on Trimble's GCS900, replaces the traditional GPS receiver and antenna. It eliminates specialized cables, which improves signal strength. A new series of modular GPS receivers, Extreme SPS850 and SPS880, is also available.
