摘要： Systems and methods are disclosed herein to use what is referred to as adaptive continuous tracking (ACT) to reduce the power consumption of GNSS receivers. In GNSS receivers, performance as measured by position accuracy is a function of the observation time of the satellites. A longer observation time translates into more reliable range measurements and demodulated data, and ultimately into better positioning accuracy of the receivers. However, a longer observation time also means more power consumption. ACT allows satellite observation time to be tuned to the desired positioning performance by dynamically adjusting the on time period of the receivers while maintaining a minimum performance metric. The performance metric may be formed from a combination of the estimated position error, the horizontal dilution of precision (HDOP), the data collection state, and the receiver operating environment as characterized by the carrier to noise ratio (CN0). ACT cyclically switches on/off the radio frequency (RF) front-end and also cyclically enables/disables the baseband hardware of the receivers to reduce power consumption while allowing the receivers to meet the minimum performance metric and ensuring continuous satellite tracking, continuous positioning fix operation, multiplexed GNSS operation, and continuous data collection.
摘要翻译：本文公开了使用所谓的自适应连续跟踪（ACT）来减少GNSS接收机的功率消耗的系统和方法。在GNSS接收机中，通过位置精度测量的性能是卫星观测时间的函数。更长的观察时间转化为更可靠的距离测量和解调数据，最终达到接收机更好的定位精度。然而，更长的观察时间也意味着更多的功耗。 ACT允许卫星观测时间通过在保持最小性能度量的同时动态调整接收机的接通时间周期来调整到期望的定位性能。性能度量可以由估计位置误差，水平稀疏精度（HDOP），数据收集状态和以载波噪声比（CN0）表征的接收机操作环境的组合形成。 ACT周期性地打开/关闭射频（RF）前端，并且还周期性地启用/禁用接收机的基带硬件以降低功耗，同时允许接收机满足最低性能指标并确保连续卫星跟踪，连续定位固定操作，多路GNSS操作和连续数据采集。
