These are more capable, but much larger (400Kg each) and presumably much more expensive.nano sats. The constellation will consist of 200 for equatorial coverage and will ultimately expand to around 1,000 for global coverage.

I can't find actual costs however I've found an article that says the 700 satellite constellation could cost as much as a billion dollars. They say each satellite will cost less than one million to build if they can keep the weight of them down.
