Another Javad convert
Actually, with a bipod, I do leave the point, go to lunch, and come back, to find a nice cluster of shots! (But you probably meant, taking the LS with you).
I meant that my I would be charging more for what I do with newer and better equipment.
Through discussions and hearing the opinions of real gurus, I've been told that 20 minutes causes enough of a constellation change to validate a new shot with different multipath conditions. I have not run into a situation that required that sort of redundancy yet. After the day is done, the points have been submitted through DPOS (Javad specific post-processing), you can look at all, and I mean all of the data pertinent to a point that you shot. If you have a pin that does not lay in where it should on the plat and you start second guessing the validity or accuracy of the shot, you can look at the data, see how long you were on the point, how many epochs were collected, I believe you can even look at each satellite that was used. I am skipping over some of the pages of data available, but it is a very detailed set of "fieldbook notes" so to speak, which can give you a warm fuzzy feeling about it or know to go back and shoot it again.
Multi-path geometry can be changed rather quickly in timber/brush areas. Slide the rod up or down and the geometry changes. I've never been able to get two bad locations on a point that matched. Two locations that are different make me reject both locations until I know otherwise, but if they both check with different fixes and different multi-path geometry I start thinking that I have something.
On another note, I either seem to be able to get a shot with the R10 or not. I've not been able to get a bad shot with one yet, all my independent checks on points have shown the R10 locations were good, even in very bad brush, timber areas. If it won't take a shot I will either try at a later time or break out the robot. Sometimes both, I've struggled with the 4400, 4700, 4800, 5700, 5800, but not the R10. The R8 is good also, just not as good as the R10 in timber.
I figure the Javad is similar, but I still have memories of the old days where bad fixes were a daily occurrence.
These Javad threads always have a P&R feel. Tribal.
Hey - Javad is great gear, at a great price point, and they give great customer service. Along with a healthy dose of propaganda. Leica, Trimble, Topcon, and several others are also great units. They all solve multiple, concurrent, redundant fixes in one fashion or another. That's been a thing for quite a while.
Wow, this went from a pat on the back for Javad (which I also own) to a dog pile on the guy for his billing practices. Reminds me of another board from long ago!
