The GPS satellite on the DVR frame of the vehicle monitoring camera was developed by the Space Department of Rockefeller International Company   The satellite weighs 774kg and has a service life of 7 years    The satellite adopts a cellular structure    with a cylindrical main body and a diameter of 1.5m El satélite está equipado con dos paneles solares de doble hoja (BLOQUE I) en ambos lados con una longitud total de 5,33 metros y un área de recepción de luz solar de 7.2 square meters    The sun orientation system controls the rotation of the two wing battery panels to keep the panels aligned with the sun    continuously providing power to the satellite and charging three sets of 15Ah cadmium nickel batteries to ensure that the satellite can operate normally in the shaded area of the Earth   A multi beam directional antenna with 12 units is installed at the bottom of the celestial body    which can transmit signals in two L - bands  19cm and 24cm waves ) with an angle of approximately 30 degrees   Omnidirectional telemetry and remote control antennas are installed on both ends of the celestial body for communication with the ground monitoring network   In addition    the satellite is equipped with attitude control and orbit control systems to maintain the satellite at an appropriate altitude and angle    accurately aligning with the visible ground of the satellite
