Following rising demands in positioning with GPS, low-cost receivers are becoming widely available; but their energy demands are still too high. For energy efficient GPS sensing in delay-tolerant applications, the possibility of offloading a few milliseconds of raw signal samples and leveraging the greater processing power of the cloud for obtaining a position fix is being actively investigated. In an attempt to reduce the energy cost of this data offloading operation, we propose Sparse-GPS 1 :doi:10.1145/2994551.2996696 dblp:conf/sensys/MisraKCB16 fatcat:5jxdu3gdfrgf5a6cexgkl6t2fi
