PPP (24hr obs CORS station)

[hadihaseri]

I’m currently working on GNSS data processing using GROOPS as part of my postgraduate research in Geospatial and Mapping Science. My objective is to perform Precise Point Positioning (PPP) on 24 hours of data collected from a Continuously Operating Reference Station (CORS).

I’m encountering difficulties at the stage involving the GnssReceiver Generator. Specifically, I’m unsure whether I need to manually create the following input files:
• inputfileStationInfo
• inputfileAntennaDefinition
• inputfileAccuracyDefinition

Could someone clarify the role of these files in the processing chain and whether they are mandatory for PPP, or if there are default definitions I can build upon?

I would greatly appreciate any guidance or examples—thank you in advance for your help.
