Explain the design and configuration of your control network. In this situation, what factors must be considered in designing the control network? In your answer, keep in mind that a precise network is required


this is my asnwer so far:
- Primary control from existing area (such as town survey markers, trig beacons etc.) 
- secondary control from GNSS which can be used as a leverage to test and support that baseline. 
- These controls won’t be on our site as there is lots of occlusions which will hinder the functionality of the GNSS receivers. 
- Then it will be introduced into our network


please add on and enchance my control pay mind that the networks we learned are the constraint, free and minium constraint netowrk Please answer in JSON format.
