   Indeed, those cases are normal in other industries, but not in mine.

   I guess I should mention that GPS position is a perfectly normal thing to include in a telemetry stream.

   Wow, that is pretty rough. That's so rough that I would consider figuring out some way to export your data from that software and then visualize it with python/matplotlib or similar.

   Fair enough. In the telemetry world the second case you mention is rarely seen. I'm sure someone, somewhere is doing something like that, so I won't say never. In flight testing you have anywhere from a few measurements to thousan

   Ah, a fellow flight test person. I don't handle the warehousing of data, so my knowledge is limited. I know a database is involved and used but I could not say what database or provide any specifics. Sorry. EDIT: I would like to know h

   I said nothing about position. But a lot of things measured have to do with how the structure of the aircraft responds to turbulence, rough air, and aeroacoustic vibration (aka flutter). So there might be modes where structural components h

   I'm not anywhere in that realm because I don't have a data system that could support such a large amount of data. But then, I also have a physical system that does not need observations of 1 million distinct things (at least, not

   I'm always amused when I see the criterion for a "very dense" time series as data being collected more than once per second. In my business (telemetry), we often record parameters thousands of times per second, depending on w

    Didn't want to say anything that I shouldnt. Hard to keep track of what is public and what isn't. Better to not say anything. Sorry.

    I too am a former Orbital employee. I worked on the sounding rocket program. It was very much a pressure cooker because of the incessant pressure to work more overtime and do more missions in less time. I always heard that other parts of th

    I do not understand the need to separate a "code editor" from a text editor. What is code before it is interpreted or compiled? Text. I do not object to the existence of Atom -- it scratches some people's itches, so that&#x27
