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>>

After choosing the most appropriate receiver for your application from last month’s survey, you may need an antenna, too. We have collected key specifications for 336 antennas from 34 manufacturers. We have made every effort to present an accurate and comprehensive listing of antenna information;...More>>

We examine the antenna designs that provide GPS functionality to mobile phones and why most phones still do not provide GPS operation indoors. We also see what it will take to make them better. More>>

Mil-Con’s rugged, sealed, field-replaceable, shock-mounted GPS Antennas use a commercial quadrifilar helix antenna element in spin-on SMA and TNC versions, as well as, slide-on SMB version. The antennas are designed using compliant RF connection that combines mechanically isolated ceramic antenna...More>>
