SOKKIA SRX ROBOT IS NOT TRACKING ATP1 360 PRISM CENTRE ?

I'm running a SOKKIA SRX with SurveCE on Carlson Surveyor+ data collector. We mainly do Urban/ Semi-Urban cadastral surveys. In one man operation tried to use Robot mode. I've setup a tripod and set the ATP1 360 prism for backsight & foresight. In TRACKING & SEARCH modes the gun locks to slightly off the visible centre towards right. For 100-150m it's about 10-12 seconds. Approximately for 150m - 7mm, for 100m - 5mm, for 50m- 2mm off respectively. If I set 0.0000 for backsight, after…See More

"Nimal, what Ivan and Troy wrote above is absolutely correct. Due the image processing, your SRX achieves better accuracy in angular measurements. This is an AP1 image from SRX camera during a service inspection in my lab: Sorry for image quality,…"

"Good explanation, it is not an error, it is the way the station works, moreover you can check the accuracy of your targets looking the residuals of your resections, and the results of your backsights"

"The SRX has a field collimation process that can correct this issue. Setup prism about 300ft away and go to the configuration/collimation IMAGE-SENSOR is normally the last in the list. Sight prism center and press measure and it will do an…"

"How did you determine there was a difference? They robot will only mechanically turn near the target and once the target is close it will only fine tune electronically. So the cross hair will not necessarily be lined up on the ATP1. Also when using…"

"Hi, I copied this comment from my Sokkia SRX manual, hope it helps Search operation during Auto Pointing 2. When the target enters the field-of-view within the set time limit for Auto Pointing completion, the SRX stops moving and the offset between…"

"It’s a radio link collimation. I would do a zero point collimation on the zenith as well."
