With the miniaturization of electronics, Global Navigation Satellite Systems (GNSS) receivers are getting more and more embedded into devices with harsh energy constraints. This process has led to new signal processing challenges due to the limited processing power on battery-operated devices and to challenging wireless environments, such as deep urban canyons, tunnels and bridges, forest canopies, increased jamming and spoofing. The latter is typically tackled via new GNSS constellations and modernization of the GNSS signals. However, the increase in signal complexity leads to higher computation requirements to recover the signals; thus, the trade-off between precision and energy should be evaluated for each application. This paper dives into low-power GNSS, focusing on the energy consumption of satellite-based positioning receivers used in battery-operated consumer devices and Internet of Things (IoT) sensors. We briefly overview the GNSS basics and the differences between legacy and modernized signals. Factors dominating the energy consumption of GNSS receivers are then reviewed, with special attention given to the complexity of the processing algorithms. Onboard and offloaded (Cloud/Edge) processing strategies are explored and compared. Finally, we highlight the current challenges of today's research in low-power GNSS.

“…We have chosen the PYNQ environment, developed by Xilinx to enable Python and FPGA interactions on their Zynq-based development boards. Advantages of going from software to hardware are multiple: 1) enabling AxC only accessible at the hardware level [9]; 2) more realistic energy consumption estimates; and 3) processing acceleration. A partial conversion should provide the best of both worlds, that is, efficient processing for computationally intensive tasks, and benchmarking tasks performed in a rich and high-level environment.…”

“…We have confirmed such computational load during our tests with SyDR.Given the amount of computations, AxC techniques could open a new door to low-power GNSS processing, providing energy consumption reductions. Although most AxC techniques can be applied or emulated in software, many of them can only be applied efficiently in hardware [9]. Moreover, as these techniques often imply consequent accuracy/precision reduction in computations, their effect on the signal tracking and positioning needs to be evaluated.…”

“…It is crucial to note that AxC can be applied only in applications that are resilient to such errors, i.e., those whose outputs remain acceptable despite some reduced precision. Examples are in Machine Learning (ML) and in DSP algorithms [9]. We note a lack of work using AxC in GNSS processing and highlight it as a promising direction for future research.…”

Global Navigation Satellite System (GNSS) is widely used today for both positioning and timing purposes. Many distinct receiver chips are available off-the-shelf, each tailored to match various applications' requirements. Being implemented as Application-Specific Integrated Circuits, these chips provide good performance and low energy consumption but must be treated as "black boxes" by customers. This prevents modification, research in GNSS processing chain enhancement (e.g., application of Approximate Computing techniques), and designspace exploration for finding the optimal receiver implementation per each use case. In this paper, we review the development of SyDR, an open-source Software-Defined Radio oriented towards benchmarking of GNSS algorithms. Specifically, our goal is to integrate certain components of the GNSS processing chain in a Field-Programmable Gate Array and manage their operation with a Python program using the Xilinx PYNQ flow. We present the early steps of converting parts of SyDR to C, which will be later converted to Hardware Description Language descriptions using High-Level Synthesis. We demonstrate successful conversion of the tracking process and discuss benefits and drawbacks arising thereof, before outlining next steps in preparation for hardware implementation.
