    The last I looked, the state of remote-sensing algorithms for limb profiling is something between bad and "are you kidding?".

    But they are not doing much "remote sensing". All they are doing is recording when a GPS signal is received. That's it. That shouldn't be too hard. The delay between when the GPS should have been received, and was actually received, will tell them the index of refraction of the atmospheric cord it passed through, and from that, a ground computer can calculate the humidity, temperature, and pressure.

    That sound you heard is the OP's point whooshing over your head. Limb profiling (what you describe) is a remote sensing technique, and it's not one that works really well.

    The problem isn't receiving the signal (well, it's not a problem in this sense though it has challenges of it's own), the problem is analyzing the signal. You have three different variables (all of which vary with altitude to boot), with no way to significantly constrain any one of them - meaning arriving at an accurate value for one (let alone three) is a Very Hard and Poorly Understood problem.

    Does anyone know why ammonia was used instead?

    I emailed a friend who worked on Station's ECLSS back in the 90's, and this was his reply:

    "Ammonia has a great specific heat (ability to carry the thermal load), plus its boiling and freezing points work really well in space applications. It's also (aside from toxicity) a very well-known, simple, cheap and fairly easy material to work with. The way the TCS loops work on ISS, the ammonia loop is external; it never mixes with the internal (water) loops. There are external heat exchangers to pass the thermal loads from inside to outside; the water loops out of the pressure vessels through the end cones to the heat exchangers and back inside. The only way for ammonia to get into the water loop (it seems to me) would be a debris strike or something like that in a heat exchanger (and they're protected by MMOD shielding, as well as being rather out of the way)."

  19. Re:Anyone who knows refrigeration? on Ammonia Leak Alarm On the ISS Forces Evacuation of US Side: Crew Safe · · Score: 1

    Is it that a leak would be dangerous even if the refrigerant were 'the warm fragrance of a spring day'; because of the life-critical nature of the refrigeration system and the relatively tiny volume of breathable atmosphere aboard the station

    I can't speak to the ISS, but one of the downsides of the fancy(ier) refrigerant we used (and still use AFAIK) onboard USN submarines was that it breaks down into carbon monoxide and (IIRC) phosgene gas under rather moderate heat. So, you had a tasteless, odorless gas that broke down into two different tasteless, odorless, substances which were very dangerous in low concentrations - inside a vehicle with a relatively small breathable volume. Or to put it another way, something that's relatively innocuous in your house can be very dangerous indeed in an enclosed environment.

    That being said, no doubt NASA compared all the properties of the candidate refrigerants (not just the danger of leak, but how well if performs in the Station's environment) before choosing ammonia.

  20. Re:This is why I like analog gauges... on Ammonia Leak Alarm On the ISS Forces Evacuation of US Side: Crew Safe · · Score: 4, Insightful

    This is why I like analog gauges with no electrical or electronic component to their basic functionality. I find I can confirm false-readings much more easily than relying on an electronic sensor

    Do you also enjoy spending hours that could be used productively doing nothing but working your way through gauges scattered across a system? Because that's one of the hidden costs of analog gauges - either you keep the system simple and keep the gauges near the point of measurement, or make it more complex and heavier by introducing a method to transfer the measured quantity (fluid, gas, what have you) to a convenient location for the gauge? (And an awful lot of what people see as analog gauges are actually voltage or resistance meters - the measured quantity is measured locally and then transmitted to a distant gauge as an analog electrical signal.)
     
    On top of that, you can only confirm false readings if it's not the gauge or measurement system itself supplying the false reading in the first place. Analog gauges do break and their calibration does drift. Piping used to transfer fluid or gas to a measurement point does get clogged up. (And people shut or forget to open gauge stops and isolation valves at the most inconvenient of times.) If it's a hybrid (analog mechanical and analog electrical) system, there's a whole additional level of potential for faults and drifting calibration (without any of the advantages that using the same wiring for digital provides).
     

    it seems like at least with automobiles, the sensors themselves fail more often than the conditions that the sensors were designed to detect actually manifest.

    The plural of anecdote is not data.
     
    In my experience, the vast majority of people who pine for analog gauges have never dealt with an analog system other than their automobile dashboard (which after the late 80's is probably a hybrid (digital with analog displays) system anyhow) or something else equally simple and only having a handful of gauges (at most) in the first place. I have (USN Submarine Service, '81-'91), and I'll take a digital system over an analog system any day of the week. They're much easier to maintain, offer far more functionality, and are much easier to use.
