Beast Mode RTK from JAVAD GNSS

By Matt Sibole

With a name like beast mode RTK it better be something pretty impressive. I think we are all looking for ways to become more productive and more efficient in the course of our fieldwork. I think the analogy could be made that beast mode RTK is to GNSS as what the EDM was to the steel tape.

Beast mode RTK is 5 Hz corrections coming from the base. While other receivers have advertised 5 Hz corrections for a long time they have not actually preformed at 5 Hz. The new Beast Mode from JAVAD GNSS actually preforms at 5 Hz. With typical RTK gps receivers an epoch is counted at 1 second which is 1 Hz corrections. With Beast Mode by JAVAD GNSS an epoch is only 0.2 seconds or 5 Hz corrections.

So, for those of you who typically measure your control and your property corners for 180 epochs, which is typically three minutes, now it will only take you 36 seconds with no discernible loss in accuracy or precision. 

So what does Beast Mode from Javad GNSS actually mean to a surveyor? Beast Mode means that a surveyor can spend more time on quality control and less time just sitting there waiting to get a fix. For instance: With the combination of Beast Mode and Javad’s Cluster Average feature you can shoot in all of the property corners on a project, then shoot the property corners again one the way back. Once you have located all of the property corners (2 times in this scenario) you can use Cluster Average and average all shots that are within a user defined tolerance, giving increased relative precision for each individual point. All of this being done in less time than a typical RTK survey with increased relative precision and having redundancy to verify that all property corners are exactly where we say they are.

This is a screen shot of the Triumph LS running Beast Mode. You can see the epoch count on this shot is 130 epochs. Right beside the epoch count you will notice that it only took 39 seconds to get all 130 epochs. The 0.110 and 0.161 at the bottom of the screen is the peak to peak error over the 130 epochs for this one shot. The HRMS value of this shot is 0.02’.

This is a screen shot after using cluster average. I located this same mag nail 4 times over the time span of two days. You can see in this screen shot that the overall spread or peak to peak error between all 4 points is 0.10 in the North and 0.05 in the east.

This is a detailed statistics screen shot of the averaged point. It gives a total number of epochs recorded with the overall RMS value. All of this information and more can all be exported in an HTML format for documentation. The redundancy of this point was completed in less time that could have been completed with any other receiver due to Beast Mode RTK from Javad GNSS. With all of this said, the bottom line is efficiency and redundancy. There is not another receiver on the market that allows for the efficiency and the redundancy that the Javad Triumph LS GPS receiver with Beast Mode RTK and Cluster Averaging offers.
