Analysis of an Arctic Polesitter
The concept and rationale are presented and the fundamental dynamical requirements set forth for a spacecraft that remains stationary in space above the North or South Pole of the earth for an extended period of time. The mathematical basis and acceleration characteristics are shown. Performance cap...

The concept and rationale are presented and the fundamental dynamical requirements set forth for a spacecraft that remains stationary in space above the North or South Pole of the earth for an extended period of time.

Performance capability using present day Ion Drive technology is evaluated in terms of stay time at the pole and imaging resolution as a function of viewing distance. The analysis shows that a Polesitter spacecraft can be maintained without difficulty for one or two years at several lunar distances from the earth, admitting large resolution visual imagery and some less useful measurements in the infra-red regime. Microwave measurements are not practical using today's technology.
