As technology continues to march forward, and storage and data evaluation use grows, the surveyor and the farmer will begin to use each other’s skillsets to increase their own productivity. So how do we get there? First, we must establish how each side uses their prospective GPS tools. read more

Leica adds to geodetic monitoring software

December 21, 2015By

Leica Geosystems has introduced two new additions to its Leica GeoMo deformation monitoring solution: Leica GeoMoS AnyData and GeoMoS API. Users of the system can now create comprehensible visualizations and customizable reports, which enables powerful sensor data fusion for applications, such as air or water quality monitoring and construction or building management. With GeoMoS AnyData and GeoMoS API, multiple open... read more

A GNSS monitoring solution integrated into a stand-alone receiver detects fast movements of man-made and natural structures in real time. The new product from Leica Geosystems, dubbed VADASE, runs onboard Leica reference stations and monitoring receivers. The Leica Velocity and Displacement Autonomous Solution Engine (VADASE) provides an in-depth look into fast movements using unique processing algorithms. In real time, accurate... read more

JAVAD TRIUMPH-LS Short Baseline Accuracy and Precision with 1 Hz and 5 Hz Corrections

December 18, 2015By

By Matt Johnson In a previous article, “JAVAD GNSS 5 Hz “Beast Mode” RTK Base Station Corrections Reduce the Time to Acquire a Fix by 72 Percent,” the benefits of RTK base station correction rates greater than 1 Hz were discussed. This article will investigate and compare the accuracy and precision of JAVAD TRIUMPH-LS RTK positions with a JAVAD TRIUMPH-2 base station... read more

You be the judge: To eLoran or not?

December 16, 2015By

Readers of GPS World, its e-newsletters, website — and all interested PNT parties — are invited to register their opinion in the current poll at gpsworld.com/janpoll. Should the U.S. government install a full eLoran network of broadcast stations to back up GPS in case of jamming, interference or other emergencies? Yes. No. More study is needed before answering this question.... read more

PPP_opening_O

A new high-accuracy technique using one dual-frequency GNSS receiver, precise point positioning (PPP) offers the possibility of cost-effectively obtaining coordinates. This study investigates the accuracy of kinematic PPP for hydrographic applications on rivers, and shows results comparable to double-difference solutions. read more
