Satellite Signal Acquisition Using Antennas with Beamforming Abilities |
| 摘要 |
Signal acquisition methods and receivers utilizing such signal acquisition methods are disclosed. More specifically, a signal acquisition method may include: identifying a list of available beam patterns that an antenna unit is configured to provide; iteratively searching for satellite signals by controlling the antenna unit to utilize one of the list of available beam patterns in each iteration; determining whether a satellite signal is detected in each iteration; collecting ephemeris data of a satellite producing the satellite signal when the satellite signal is detected in each iteration; and controlling beamforming operations of the antenna unit for satellite signal acquisition based on the ephemeris data collected. |
