ADDITIONAL ERROR OF LOCAL VERTICAL SENSOR OF 8201 TYPE INSTALLED ON METEOR-M № 2 IN CASE OF SUN ENTERINGITS FIELD OF VIEW NEAR THE HORIZON
An additional error of local vertical sensor orientation in case of sun entering its field of view near the horizon is considered in the article. The ‘dawn’ event, i.e. the sun rising above the horizon before the ‘Presence of sun’ signal is generated by the sun protection sensors of the device, is analyzed. The issue of choosing an activation threshold of these sensors is studied.
