Monitoring on Horizontal movement of some points

Hello
Firstly sorry for my Russian I will write in English
So I have 3 reference point which are red on the photo and I want to control green points movements very precisely from this red points red points are built very strictly and there is no chance of movement but green one is like little dam structure. if I have very precise total station 0.5" Trimble S9 and trimble business center how to measure this point precisely and process in to this software. standard measure topo function is not effective I think I want to use all angle measurement precision of this instrument instrument is all calibrated
thank you there is draft below in the attachements

if we consider that it is longer edge there is just draft and might be I have wrong scales sorry for that. so and if it would be far enough what method should I use and how by s9 0.5"

 

Is it possible to take reds as occupied points? With sufficient accuracy sure.
Are em in direct visibility between each other?
Certainly, scales, elevation and distances between all measurable points have importance too

 

yah they are visible between each other, so I wander if you have this situation what will you do step by step with s9 0.5" , trimble business center, trimble travers kit
with tripod and so on, and you have opportunity to place precisely on that green point your equipment. and i wander case when you can built this type red reference points too much numbers might be 7 or 8 points to control green points, what will you do in both case.

red points are this type approximately but more stabil with it thermal isolation and so on

 

No there is no opportunity use gnss it is dam type building.

 

concrete

 

bekabarna, One way is to use dedicated module - Trimble 4D Control Site Setup https://apps.trimbleaccess.com/Trimble/4D_Control_Site_Setup.
Other way is to run repeated measurements of monitored points and control points. For higher accuracy you can run 10 or more sets. Then import project to TBC and adjust the measurements with used control points. During next session rename monitored points and repeat all the procedure. So, after few sessions you will the motions of monitored points. Any way you should also check the stability of control points itself.

 

In my opinion, there are very few reference points. Only one plane can be built on three points, but it is very difficult to track the dynamics of their displacements.
Therefore, sustainability estimates will be very approximate.

 

how to check dynamics of reference points there is nothing completely fixed in nature if we want to suppose something fixed for reference

VVV,
do you have chat to send you real documents to check and give advice?

 

Из схемы я не понял каковы размеры проекта и каковы расстояния между опорными и мониторными точками. Если расстояния относительно небольшие (до 500 м) то S9 0.5 сек вполне пригоден как для наблюдениями за призмами на плотине, так и за опорными точками. Как понял ГНСС у них нет, да и на малых расстояниях он будет уступать по точности такому тахеометру. Для определения стабильности опорных точек просто нужна отдельная программа наблюдений, может более интенсивная. Те кто эту сеть закладывал думаю были достаточно грамотные люди и если опорные пункты заложены на скальных грунтах или уже несколько лет отстоялись, то опираться на них вполне реально. ГНСС хороши если есть возможность развернуть автоматизированную систему с ежесуточными наблюдениями, малая зависимость от внешних условий и большая статистика.

 

Мы можем теоретизировать сколько угодно на данную тему, но если почитать исходный пост и посмотреть фото, то складывается впечатление что все уже давно заложено, есть у товарища конкретный прибор и софт, но нет опыта их использования. Просто ему нужно продолжить программу мониторинга плотины. Конечно в теории хорошо бы все это оснастить и ГНСС, мониторить и контрольные точки, но здесь похоже явно не тот случай. На прошедшей недавно конференции http://con-fig.com было два доклада на эту тематику, причем один и наш. Если интересно, посмотрите - https://con-fig.com/wp-content/uplo...lnoj-geodinamiki-geodezicheskimi-metodami.pdf и https://con-fig.com/wp-content/uplo...multisistemnyh-GNSS-tehnologij-v-geodezii.pdf

 

sorry but I do not speak about using software, I need to create geodetic monitoring network and do not know how, want to use triangulation measurement easy to click on keys but hard to make precision measurements. I need to make precise network around dam structure if anyone is interesting for helping me I can send him Old network point of triangulation monitoring network. just everything is lost from archive and I want to make new measurement.

 

It is not clear - are any points (monitoring and control) still exists or you will install new one? Is this project in Russia? You can send to me Old network plan with scale and present status of points.
