Adding GLONASS to GPS gives a total of about 50 satellites, for a significant improvement in navigation availability, reliability, robustness, and convergence time through a new multi-GNSS precise point positioning (PPP) service. System performance and field results demonstrate that there is no...More>>

December traditionally brings a time to appraise the old year nearly ended and peer into the mists from which the new year will soon emerge. December 2009 has particular importance as it marks the end of a decade in which GPS became a consumer item, and GNSS indelibly entered the consciousness of...More>>

Magellan Professional has made available a major firmware release for its MB 500 OEM GNSS board. The MB 500 OEM board is available in a variety of configurations from L1 GPS+GLONASS up to L1/L2 GPS+GLONASS+SBAS to adapt to various customers' accuracy needs.More>>

Over the last few months I have been scoping a brand-neutral network RTK (N-RTK) to cover around 2,000 potential users. This has involved talking to farmers, miners, surveyors, civil engineers, and other prospects about precision GNSS, and I would like to share some of their opinions (and...More>>

The Fiber Optic GPS Antenna Link (FOGPSAL) is a complete system that allows users to convert the GPS carrier from RF to light, transmit it up to 10 kilometers, then reconvert it back to RF for the GPS receiver.More>>
