Peter, this is really something to think about. Your conversation only highlights that the smartphone are very inefficient at doing things at the moment and the main cultprit is the software. Software capabilities are very limited at the moment and software codes from one platform to another are very difficult to be compatible. Do you think that more development will happen in software domain.
Still their 2Q results was in red and situation does not seem good for the rest of the year. Probably ST needs to streamline their process and cut the operational cost as the MEMS market is going to be more competitive.
As a certain editor-in-chief of mine once taught me "never assume."
I suspect that as handsets are readily available in every county on earth, so the inertial MEMS sensors (accelerometers and gyroscopes) and GPS units are also readily available and probably not considered with a separate ban.
Peter-Agreed always a threat accurate or inaccurate. However, the more distant the country the greater the need for accuracy. If the potential threat is from a close neighbour, for example as might be the case with Israel or South Korea and the receiving country is small, then given the warhead and the primary delivery vehicle, ballistic accuracy is enough to give rise to the great concerns expressed by those coountries. The North korean threats against the USA would require a mucher higher degree of accuracy to be effective and possible.
My recent contact with some of the electronics now used by the aircraft modelling community and what they are doing with it is quite remarkable. I was shown one example of a system that transferred coordinates from a mobile phone into the guidance system of a model aircraft prior to its flight. It may be that drones (model aircraft) with biological weapon payloads might be a greater threat than nulclear, especially in respect of problems with near neighbours. Easy to construct in secret, difficult to detect in flight and the esential low cost guidance components easy to obtain as highlighted in your article. I assume that there is some ban in place with respect to shipments to some countries.
What is frightening about all this "Robin said. Gyroscopes and microphones are set to benefit more than average in the short time followed by integrated inertial measurement units (IMUs); pressure sensors used for vertical positioning; and RF MEMS for improved multiband, multiprotocol performance" is the ease with which it is now possible to construct an inertial navigation system. Although there are many countries seeking to obtain nuclear weapons capability, even given the weapon and the primary delivery system, their capability becomes a really serious danger when they can accurately deliver the warhead. That is where most of the difficult, time consuming and costly development problems rest. Now it would appear low cost COTS inertial navigation systems are becoming available to all and sundry.
