I am evaluating suitability of two quectel Satellite modules for my client. The modules in question are BG95-S5 (preferred) and BG770A-GL. I want to start designing hardware but Hardware Design documents for both modules are missing (not found on product page). Also we need to check the NTN features if they match our needs. Mainly we want to be able to perform GEO and GSO attach with simulated GNSS position. I’ve seen a mention of AT+QGNSSINFO command online but I’d like to confirm this with official docs. I’d also want to check how to switch between Terrestrial and Non-Terrestrial networks.
Hardware desing is the same as for terrestrial-only modules. Regarding BG770A-SN NTN documentation see BG770A-SN documentation.
If you want to set the position manually, you can use AT%NTNCFG="FIX",<lat>,<lon>,<alt>,0 on BG95-S5 or AT+QCFG="ntn/pos","stat",<lat>,<lon>,<alt> on BG770A-SN.
But there’s more to configure for the connection to work.
AT+QGNSSINFO is for CC660D-LS module.

Thank you for the position commands. Good to know that all satellite modules support simulated gps coordinates. Is there a document describing NTN parameters configurable via AT+QCFG or AT%NTNCFG commands? Is there a command to force the modem into Terrestrial mode?
For the documentation you have to ask Quectel, I don’t think they are publicly available yet.
You are asking about two modules that have slightly different command set, so make sure you’re using the proper ones.
To force LTE-M or terrestrial NB-IoT you can use AT+QCFG="iotopmode" command as described in the documentation for non-NTN modules (values 0, 1 or 2). Using value 3 you can switch to NTN. If you’re using BG95-S5 this document can help.
