Apparatus for transmitting positioning signal, positioning system including the apparatus, and system for transmitting positioning signal

Image Number 14 for United States Patent #7817090.

An apparatus that can transmit a signal enabling higher accuracy of calculating positional information is provided. A transmitting apparatus transmitting a positioning signal includes an oven controller crystal oscillator (OCXO) having a thermostatic oven that keeps the temperature of a quartz resonator constant and oscillates such that variation in output frequency caused by the ambient temperature change is minimized, a voltage controlled oscillator (VCO) outputting a signal modulated in accordance with the signal from OCXO, multipliers, a code generator outputting code patterns for respectively identifying each of artificial satellites on which the transmitting apparatus is mounted to multiplier, a memory storing a navigation message, a transmitting portion, and an antenna.
