Carlson Viking GNSS Receiver with Triple-Fix RTK Technology

This title was summarized by AI from the post below.

The world-leading Carlson Viking GNSS receiver integrates "Triple-Fix" RTK technology at the core of its performance. "Triple" refers to the 3 completely separate RTK engines that process the satellite signals. The Viking uses 3 RTK engines: Carlson's own, superior, next-generation GAMA® RTK engine in combination with 2 engines from independent organizations. By comparing and processing the results from the 3 engines while using Carlson's GAMA engine for the greatest accuracy and speed, the Viking will report "Triple-Fix" through your Carlson field software when sufficient agreement is reached. This unique approach essentially eliminates "false-fix" errors, providing both accuracy and certainty in your position, even in the most challenging situations.

the key is still at the measurement level, if the gnss signal tracking give good and reliable GNSS code and carrier phase measurements, then most RTK engines will behave more or less the same, even the simple RTK engine based on open-source code. If the measurement is bad, then three different RTK engines may give the same wrong answers. But triple RTK engines do give some cross-checks and provide better reliability. If the CPU resources is not a concern, running parallel RTK engines with different parameters (code and phase measurement stochastic models, different set of observations, different set of satellites) definitely give better reliability

So funny ... or at least you don't know how the amb's are fixed ?
