LIVERMORE, Calif. –
Topcon Positioning Systems (TPS) announced the release of Firmware
4.0 on all Topcon OEM GNSS platforms.
The new firmware version introduces Quartz Lock Loop (QLL) technology. Designed
by Topcon engineers for “superior GNSS tracking in high-vibration
environments,” according to Douglas Langen, TPS product manager for GNSS
systems, QLL technology is an “exclusive approach to mitigating the effects of
shock and vibration through patented firmware algorithms.”
Langen said, “Most high precision GNSS receivers use crystal oscillators to
establish a precise timing signal, which relies on the natural resonant vibration
of a quartz crystal. This conventional approach can provide suitable
performance in smooth dynamics, but when exposed to severe real-world vibration
and shock, these simple systems can destabilize quickly, leading to inaccurate
GNSS measurements or even complete satellite tracking failure.”
By using advanced feedback loops, Topcon’s patented QLL “continuously monitors
system behavior to detect and remove any fluctuations that may cause tracking
problems – over a full range of vibration frequencies and magnitudes,” Langen
said. “This allows for a clean, stable timing reference signal to be preserved
through strong acceleration, vibration and bumps – for uninterrupted and
reliable precise positioning.”
Additionally, Firmware 4.0 adds many new features and improvements, including
optimization of the RTK and DION positioning engines, initialization
improvements to the VISOR heading determination engine, expanded web interface
features and file management improvements.
