Method and system for indoor global navigation satellite system detection utilizing low-earth orbit satellite signals |
摘要 |
Methods and systems for indoor global navigation satellite system detection utilizing low Earth orbit satellite signals may comprise receiving low Earth orbit (LEO) RF satellite signals utilizing a LEO satellite signal receiver path (LEO Rx) in a wireless communication device comprising the LEO satellite signal receiver path and a medium Earth orbit satellite signal receiver path (MEO Rx). A received signal strength indicator (RSSI) may be measured for the received LEO signals and an expected received MEO signal strength may be calculated. A power level of the MEO Rx may be configured based on the calculated MEO signal strength by powering down when the calculated expected MEO signal strength is below a threshold level for MEO positioning purposes and/or powered up when it increases above the threshold level. The RSSI may be measured at a plurality of points along the LEO Rx. |
