Jamal,
If you are to be using Palestine_1923_Palestine_Grid and you know for certain that your control points are in the same coordinate system, then there is no need to modify anything related to the parameters of your projection files.
I said Zeno Connect allows you to setup your coordinate system as well as an associated transformation based on your corrections. Is your Leica representative also the owner of the real-time network you are receiving RTK corrections? They should be able to tell you what coordinate system the real-time network is referencing regardless of which software you are using for field collection.
Jamal,
You are likely going to have to test each transformation against known control to better gauge which is the correction transformation. I am not familiar with your coordinate system, real-time network, etc. so I cannot help there.
If you are using Zeno Office/Zeno Office on ArcGIS and Zeno Field, your transformations are setup in your Survey Dataset/Survey Project. the coordinate system tab you highlighted in Zeno Field is only for the geoid model, which is applied in the Survey Project along with a transformation, if needed. If you are using Zeno Connect with Esri ArcPad, then the transformation is handheld in Zeno Connect. Note that ArcPad and Zeno Field are similar applications, but Leica's Zeno Field enables advantages to high-accuracy field data collection.
Mountpoints are defined by the real-time network provider. Each mountpoint is a unique product and you must select one compatible with your GNSS hardware. RTCM is utilized by most, if not all, GNSS equipment, including Leica. If you are receiving a phase-fixed solution and roughly 1cm accuracy, your parameters are set correctly for your real-time network. From there, it is based on the coordinate systems and transformations being applied.
If I am understanding the response correctly, this looks accurate to me.
The most efficient way to take data to the field when using Zeno Office/Zeno Office on ArcGIS and Zeno Field is to utilize the EasyOut/In process. From your geodatabase the process creates an EasyOut folder with the necessary files files to be utilized in Zeno Field on your CS25 unit. Once field collection is completed you start an editing session and EasyIn the field data.
If using Zeno Connect and ArcPad, you will utilize the ArcPad Data Manager, which is a similar process to the EasyOut/In process, however, the Survey Dataset and Survey Project allow for transformations, CSCS files and geoid models.
