摘要 |
An apparatus that can transmit a signal enabling higher accuracy of calculating positional information is provided. A transmitting apparatus 200 transmitting a positioning signal includes an oven controller crystal oscillator (OCXO) 210 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) 220 outputting a signal modulated in accordance with the signal from OCXO 210, multipliers 240 and 260, a code generator 230 outputting code patterns for respectively identifying each of artificial satellites on which the transmitting apparatus 200 is mounted to multiplier 240, a memory 250 storing a navigation message, a transmitting portion 280, and an antenna 290. |
