(OFT) agreed with the core findings of the study and decided to start an Operationally Responsive Space (ORS) Initiative consisting of a series of experiments. TacSat-1 is the first experiment in this OFT initiative. The TacSat-1 experiment received go-ahead on 7 May 2003. The TacSat series of experimental spacecraft are designed to allow military commanders on a battlefield to request and obtain imagery and other data from a satellite as it passes overhead. Collected data will be delivered to field commanders in minutes rather than hours or days. All TacSats have been launched on
