The biggest advantage of nano- and pico-satellites is that they are a bargain. Most of the cost saving comes at the launch stage. Unlike conventional satellites, they don’t need a dedicated launch vehicle where they are the primary payload. “They’re so small they can hitch a ride on somebody else’s rocket,” Santos says. NASA’s nanosatellite missions cost two million a piece as opposed to the tens of millions needed for a conventional satellite.
Their affordability also comes from being built with off-the-shelf electronic circuit chips such as microprocessors and radio frequency transmitters and receivers. These are the same components that are inside smart phones, hand-held Global Positioning System units, and digital cameras.
In fact, the miniaturization of electronics has been the driving force behind small satellite technology, making it affordable, says Twiggs. “Electronics today are much more power-efficient than electronics of the past; that helps us,” he says. “Ten or fifteen years ago we couldn’t have found the components for the price that we could’ve afforded.”
