Bottom line: He didn't know what was right. Said that 5 Hz sounds right.\r\n\r\n(He said that the Stratux is sending GPS at 15 Hz! I wonder if that's the RY835ai board? In any event, he said that 15 Hz is too fast.)\r\n\r\nI know that iFly updates their screen once every second. I don't know if they're using any extra data in the background during that time. But I'm thinking that when they get Synthetic Vision going, 5 Hz GPS will be better than 1 Hz. (Might help stabilize the big picture with Kalman Filtering or something.)\r\n\r\nSo how about this: If you have the time and the inclination, how about putting in a commented Developer's Option for the 5 Hz GGA string. (I suppose that will require a code change to 9600 baud, and then another code change to sniff for a cold start at 4800 default or a hot start at 9600.) If you know the cheat code for 5 Hz on the VTG, you could put that in a commented Developer's Option too.\r\n\r\nThat way, even if you don't feel like coding the 9600 baud change/check, the not-well-documented commands you found will be preserved for posterity and perhaps, if needed, someone else in the future could use them.\r\n\r\n\r\n\r\n"}}
