How the Internet of Things Now Drives Location Technology
The number of devices connecting to the Internet is growing fast. The applications running on them require location context to determine the most likely use case. These devices need continuous location — not necessarily noticed or activated by the user, but always on. The specification that becomes important is energy per day: the device must maintain its location without draining its battery — and increase location availability indoors. That creates new design requirements for hybrid capability. read more

Figure 2. U.S. trade in GPS equipment, 2013 (millions of dollars).

This article is based on a presentation to the National Space-Based Positioning, Navigation and Timing Advisory Board in June 2015. The study reported on at the meeting was requested by the National Executive Committee for Space-Based Positioning, Navigation and Timing. It demonstrates the widespread use and importance of GPS to the U.S., with estimated benefits in 2013 of about $56... read more

Collecting Points in Difficult Environments with the JAVAD TRIUMPH-LS

A TRIUMPH-LS collecting a point under tree canopy.

By Matt Johnson Fundamental in the determination of GNSS solutions is resolving the correct number of full cycles of the carrier signal (so-called fixing ambiguities) in order to resolve the ambiguity differences between the base and the rover. Distances measured from GNSS receivers contain errors caused by inaccuracies in the satellite and receiver clocks, the satellite orbits, and by the... read more

L2C and Next-Generation Smart PNT Receivers

August 12, 2015By
SVN49 in space  (artist’s rendering).  The signal anomaly from SVN 49 alerted researchers to new possibilities in analysis and monitoring.

Are you using a legacy-model PNT (position, navigation and timing) receiver or a smart PNT receiver, and why does it matter? Don’t have a clue? Read on! Hint — L2C and CNAV (civilian navigation message format) are the major reason it matters. Yes, it’s all because of L2C, the controversial GPS civilian signal that seems to always be in the news and just... read more

Form Factor and Portability of Triumph LS: As High as Your Pole Can Reach

July 29, 2015By

By  Matt Sibole I follow the surveyor connect message board and have seen some general discussion of the form factor of the Javad Triumph LS. I wanted to go into a little more detail on the form factor and portability of a couple of the receivers in the Javad GNSS lineup. Most surveyors that have been using RTK GPS equipment have been trained to... read more
