The gross system product, or GSP, was the amount that a star system's factors of production and sold on the market at any given time.

In 1900 PD, the Solarian League had the largest GSP, while the Star Kingdom of Manticore had about seventy-eight percent of the Solar System's. (HH1)

In 1903 PD, Masada had a very poor economy; when the People's Republic of Haven gave Masada two warships, they became eighty percent of the star nations's GSP. (HH2)
