Voorlopig zijn het dromers op geldjacht.With over 1,000 patent claims, the technology is highly proprietary, and exactly how it works cannot be disclosed.

The SpaceMobile satellites are unusually large for LEO systems, they weigh more than a tonne each and are up to 10 times bigger than the norm because they are, essentially, cell towers in space. They are fitted with 900 square metres phased-array antennas and moving the satellites around will be complex in the extreme. NASA says, "For the completed constellation of 243 satellites, one can expect 1,500 mitigation actions per year and perhaps 15,000 planning activities. This would equate to four manoeuvres and 40 active planning activities on any given day."
The constellation will orbit at a height of 720 kilometres but the company is keeping schtum about whose and which rockets will be used to loft the satellites into space, and the satellites are big. So big in fact that a couple of months ago the US space agency NASA, having looked at SpaceMobile's plans, complained the "extremely large satellites when in orbit will engender an unacceptably high risk of a catastrophic debris-producing collision."
The altitude and orbits of the SpaceMobile satellites are uncomfortably close to the "A-Train" line of 10 earth-science monitoring satellites operated by NASA, the US Geological Survey and scientific bodies in both France and Japan. A NASA statement says. "Historical experience with the A-Train constellation has shown that this particular region of space tends to produce a large number of conjunctions between space objects". In other words, a series of accidents waiting to happen and a massive threat that will need to be completely mitigated if the new constellation is ever to fulfil its undoubted potential. Expect serious regulatory oversight.
