Dr. Javad Ashjaee on his new Triumph:

This video is of an ESRI session given by JAVAD GNSS (its owner Javad Ashjaee has made waves in recent years with his new line of GNSS receivers).

"Brought to you from Russia with love," Ashjaee quipped as he opened his talk, playing off the James Bond movie and the fact his company has an R&D facility in Moscow.

JAVAD receivers work with ArcGIS Server using an internal modem, and they have an internal RTK engine, yielding centimeter-level accuracy in real time.

The Triumph microchip, which gives 216 channels for GNSS signal tracking, lies at the heart of JAVADs technology. As a result, JAVAD has become the first receiver to work with ArcPad data collection software out-of-the-box to give survey-grade accuracy. The Quattro package has four receivers and antennas—all-wheel drive, as he calls it—yielding 16 baselines, making it effective for machine control applications or under canopy.

Ashjaee then proceeded to tell us how GLONASS has a receiver bias between the antenna and data collector, often making the signal inferior to GPS. He says his firm calibrates the bias with an accuracy of .2 millimeters dynamically and continuously; this makes GPS and GLONASS identical.
