A few notes, for those who don't yet own an LS. These difficult shots are for real. They are the PRODUCT of a series of FIXES, with RESETS, Go fixed, RESET. And, they have typically 100-500 epochs of data. Then, MORE resets. So, imagine going to a difficult place, and going fixed for a minute, storing the shot, come back on 15 minutes, repeat. Do this 4-5 times. All the points are within 0.08' with an outlier, at 0.12' away. Use a weighted average, and this is ONE SHOT in the LS. However, it usually completes this task, within 5 mins.
Sometimes, it takes longer. However, the NUMBER ONE GOOD THING is that you can have complete confidence, that you are within the accuracy that it tells you.
This is done with the following settings:
Press start.
It goes through a series of gain fix, and reset. Until it is around 90% sure it has the right location within 0.16'.
Then, it goes to phase 2, where it narrows it down, within the 0.16' to whatever is the best it can do, for that multipath environment.
Then, it goes to phase 3, which is similar to phase one, where it makes SURE it has the right place, within 0.16'. (Think checking the foot each way, of what you called out, when using a tape)
Finally, you are prompted to store the shot.
This is all done for you. You don't have to do it manually, like we used to do, with the TDS Data collector.
Then, if the error ellipse is larger than desired, repeat the observation. Or, if greater confidence is desired, repeat it.
So, often, we find shot 2 is within 0.08' of the first observation. Then, shot three is similar. Then, we use an automated weighted average, to generate the AVERAGE of those 3 observations.
THEN, on top of this, we have a POST PROCESS answer, and often this also agrees, within 0.08 or less.
So, my point is, we have a VERY strong statistical verification of what we are doing, that's automated.
This makes us very happy.
It's what makes a Javad User.
Thank you,

PS, I spoke with another fellow Javad-ite, and he told me that he dared NOT take a pic, of where he'd been, with his LS, because those who do NOT understand, would not believe him!
HA!
