Energy-Efficiency Considerations For GNSS Signal Acquisition
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 also offering reduced computational costs and power consumption compared to traditional GNSS receivers. The survey various energy-efficient methods for GNSS acquisition and present a discontinuous-reception acquisition algorithm, analyzed with both simulated and measurement-based data.
