A high-orbit optical remote sensor vacuum hot test external heat flow simulation method comprises the steps of firstly determining solar radiation heat flow according to on-orbit solar absorptance of an optical remote sensor (3), secondarily arranging the optical remote sensor (3) in a vacuum environment simulation chamber (1), then determining a 'sun outage' time period by judging whether the solar radiation heat flow Q1 (t) absorbed by an optical system within a orbit period is 0 or not, determining the time period of the Q1 (t) unequal to 0 as the 'sun outage' time period, adopting a solar simulator (2) and electric heater combined simulation scheme to perform outer heat flow simulation, determining that the time period of the Q1 (t) equal to 0 is a 'non-sun outage' time period, and adopting an independent electric heater simulation scheme to perform outer heat flow simulation. The problem that an existing non-contact space optical remote sensor outer heat flow simulation method does not have a solar spectral energy spectrum characteristic and directionality is solved, energy distribution of solar spectrum of the remote sensor on orbit can be accurately simulated, simulation accuracy is high, and project realization is promoted.
