Cost of 1,000,000 gps modules + other bits?

Un bel giorno snipped-for-privacy@meeow.co.uk digitò:

For these numbers, I think it would be *much* better to develop your own GPS receiver by starting with a standard chipset (see for example

I really have no idea, but by guessing I would say something between 1 and

Right... GPS in bulk will cost you on the order of $20 (us). Define map.

You cost the bits. GPS $20, then work out how much power the solenoids use, and if they are really the overall cheapest way of doing it (if the aim is to move the device, then they are almost certainly the wrong thing), now take that power number, and go to various solar websites to work out how the solar cells will perform in your target location and orientation. Now, that gives you the size of the solar array and battery, which lets you cost them, ...

No wonder they said that the new ID cards for the UK would cost £9 billion

What's that saying.? 'If you have to ask "how much?", then you can't afford it.

Don't forget the plastique.

world map, but with minimal detail. Merely needs to distinguish betwen go and no go zones, with low resolution. 200 yards per pixel would be absolutely fine, with 1 bit information depth.

Since the go and no go areas are mostly very large, (mainly countries and continents) this info could be heavily compressed.

It might alternately be possible to rely on GPS derived info.

yes... was just hoping for the chance to save some time here, since I probably only need a very approx figure. Only if it makes sense at tis stage is it worth going as far as a real design and costing.

sounds good

theyre just for control

target location: all over the world. Orientation: every which way. I think I now have another method of powering that would be better and cheaper.

Yep. I want to do it the lazy way first, to see if its worth finding out the figures for real.

A floppy drive has a similar amount of and type of stuff in it, excluding the GPS, and costs 10 retail, so about 5 at the factory gates. It includes the power source (the stepping motor), or something very similar to it, the tronics, connectors, skeleton housing, testing etc. Add gps @20, Looks good.

All that remains is to get a ballpark on the price of the big egg.

Thank you, NT

One method of estimating that can work if you have limited knowledge in the domain is to to look at (technically) similar items (those with reasonable competition) and what they sell for through similar distribution channels. Your item should be salable at a price at least as high as they sell for in order for it to be practical. Preferably a fair bit more.

Sounds like it's Cost+10% so who cares? Any large figure will do!
