Space Systems Command Seeks Less Costly GPS Constellation for Rapid Launch

The Space Systems Command is eyeing ways to expand the Space Force’s GPS spacecraft constellation and is seeking industry ideas for launching demonstration satellites rapidly at low cost. 

According to a request for information posted on Sam .gov, the SSC wants industry inputs about GPS satellite systems on medium-Earth orbit, designed with lifespans of three to five years and a six-month launch window after contract award. The RFI also seeks appropriately sized spacecraft that would enable the launch of multiple satellites on each mission. 

The Space Force currently operates 31 GPS satellites delivering a range of capabilities, C4ISRNET reported Saturday.

The SSC’s new RFI kick-starts the government’s goal of developing tranches of demonstration prototype spacecraft with increasingly complex features. The first tranche, which is called Rapid Prototype Demonstration Tranche 0, will demonstrate broadcast capability on GPS subset signals compatible with existing GPS user equipment. The subsequent tranches’ objectives include launching new GPS capabilities, such as broader signals and regional military protection.

Lockheed Martin built the latest Space Force satellites, which are dubbed GPS III and deliver an M-code capability for military users.
