Pass through formula, frontier tracing formula and radiation thermal balance type.Linear array static state infrared earth sensor is that a kind of typical radiant heat is put down
Weighing apparatus formula earth sensor, because without moving component, volume and quality are smaller, low in energy consumption, is particularly suitable for long-life aerial mission,
Be widely used in absolute orientation detective, meteorological, communication, provide etc. on artificial satellite.
Linear array static state infrared earth sensor (hereinafter referred to as earth sensor) typically has at equal intervals symmetrical 4
Individual optical system.Each optical system receives the infra-red radiation from earth different piece respectively, by each optical system
The different infrared energies for receiving are analyzed and draw spacecraft attitude.For example earth sensor works as all optical systems
When reception energy is equal, represent that spacecraft attitude angle is zero.When former and later two optical systems reception energy is unequal, boat is represented
Its device has attitude misalignment in pitch axis；Similarly, when the visual field reception energy of left and right two is unequal, expression has appearance in the axis of rolling
State deviation.
The performance and precision of earth sensor will directly affect satellite working condition in orbit.In order to sensitive to the earth
Device carries out performance test and precision calibration, it is necessary to be on the ground its a set of special performance test apparatus of exploitation, i.e. earth mould
Intend device, simulate the earth infrared image seen when earth sensor runs under different tracks, different attitudes, realize that the earth is quick
The ground test assessment of sensor performance indications.
The content of the invention
