Abstract: A method to calculate position of a platform using a detection and ranging system coupled to the platform to transmit a signal to space object having a known ephemeris. The detection and ranging system receives the reflected signal from the space object. Taking the range of the platform from the space object using a time delay between transmission of the signal and receipt of the reflected signal and the range-rate using a Doppler frequency shift between the transmission of the signal and the receipt of the reflected signal makes it possible to calculate a position fix of the platform using the determined range, the determined range-rate, an altitude of the platform, and the known ephemeris of the space object.

Abstract: A method for neutralizing electrostatic charge comprising the steps of placing a first conductive body in contact with a second conductive body, wherein the first conductive body is proximate to a charged object; inducing a positive charge on the first conductive body and an equal amount of negative charge on the second conductive body; electrically isolating the first and second conductive bodies; connecting the first conductive body to the negatively charged object long enough to neutralize excess positive charge; placing the second conductive body in contact with an electrical receiver; transferring excess charge into the electrical receiver; discharging and isolating the conductive bodies; and bringing the conductive bodies back into contact with each other.
