RTK Rate

Gentlemen,

From what I understand, the LS has a maximum RTK rate of 10hz.

The LS Plus and T3 look like they are 20hz receivers. If so, is this the max RTK Rate the processor can accommodate? Does a change from 10 to 20 hz decrease the collection time by 1/2? The options page for the T3 will allow selection of 50 and 100hz. If this is possible will the collection time per point really be 1/5 or 1/10 of the time it takes at 10 hz.

Thanks Adam.

I understand what you are saying with respect to moving objects. What I am not understanding is why going from 1 to 10 hz (as in the beast mode development) had such a profound impact but going from 10 to 20 or 10 to 50 hz would not achieve similiar results, based on the given ratios, of course.

When beast mode was developed, we went from about 1 to 5 hz. At the time I asked this same question and the response i was given was that the processor can't keep up with more than 10. The new chip in the T3 has prompted my question.

My sense is that the new chip maxes out at 20. So, the LS plus can potentially collect the same number of points (as original LS) in half the time. Several surveyors here have said the plus is about twice as fast as the LS (I assume there is much more to the increased efficiency that just the RTK rate).

Am I misunderstanding one or more concepts?

Position rate and solution rate are two different animals. Position rate maxes out at about 5Hz (five times per second). Position rates are possible up to 100Hz in some devices and Javad announced at Intergeo that we can now support 200Hz with some devices. These position rates don't recompute the integers as the solution rate does, but the position rate will output the position of the antenna based on a fixed solution that is already determined.
