Abstract

Together with an increasing number of functionalities related to communications, positioning, and sensing, energy efficiency is becoming more and important in chipsets for emerging wireless systems, and, in particular, for those meant for low-power applications. Future miniaturized sensors, to be used for example in bee-sized drones, mini-satellites, or wearable devices, are likely to include GNSS chipsets supporting accurate outdoor localization and, at the same time, offering reduced computational costs and power consumption compared to the traditional GNSS receivers. This paper offers a survey on various energy-efficient methods discussed so far in the existing literature in the context of GNSS acquisition and focuses on a case study based on a discontinuous-reception acquisition algorithm, analyzed with both simulated and measurement-based data.
