Topcon introduced HiPer Lite+, a completely cable-free RTK GPS+ system. GPS+ is Topcon's advanced dual-constellation satellite tracking-GPS plus GLONASS-currently providing almost 50 percent more satellites than GPS alone. HiPer Lite+ incorporates all features of the standard HiPer Lite including the advanced, internal 915 MHz spread spectrum radio designed specifically for close-proximity GPS+ antenna operation. This eliminates multiple components, connections and external power requirement of traditional GPS base stations while still providing precise measurement up to 1.5 miles away from the base.
