Hi, I am new in this forum and we are using a javad sigma, especially for measuring instrument landing systems. However I want to use this device too for developing a testdrive equipment for measuring surface multilateration systems. At the moment I can dump GGA and RMC NIMEA messages on serial com port. Is there a possibility to configure some more messages like gsa,... I did some research and found out that javad netview should be used for configuring the device - nevertheless I couldn't find any option neither in the software nor in the manual how to do this. Could give me some support please how to realize this! Thanks a lot
