How to read two file in two different band? #410

Open Tanggeshi opened 4 years ago

Tanggeshi commented 4 years ago

I want to run gnss-sdr in dual-band mode by reading two different file in two different band, would you please give an example configure file ? Thank you!

Hi @Tanggeshi ,

this is the configuration example of a GPS L1 + Galileo E1 + GPS L5 + Galileo E5a receiver we use in our CI system, working with two files in different bands. They need to be captured synchronously and at the same sample frequency.

@carlesfernandez Thank you so much! It can run in two band mode now! But I cannot get Rinex file after it stop normally. I can get Rinex file when I use one file and one band. Is there any advice to check this problem?
