Hi!
I have a question about IMU on this module. Who is responsible for the fusion of IMU readings with GNSS data? Will this be done on the module side or this will be just another sensor for Ardupilot?
Does anyone use this module and have some testing results?
fusion done inside um981
Thank you for your response! Have you used it successfully previously?
Just ordered sample in process, could posting some data later here
That would be great. Iām using UM980 and wonder if UM981 will bring any improvements. It is also interesting how Ardupilot will behave with zero satellites and position information in the same message.
I have um981 based gnss receiver, it works just like um980 but how can I use the SLANTAPA message with imu data if my app cannot read it 
, wish I could just change the message header/ data order to one that is familiar to my app(for example in this case it requires header $INS.NAVI)
