Dutton e education institute college of earth and mineral sciences the pennsylvania state university. Previously gps and sdr enthusiast e p showed us on his blog how to use an. Jan van sickle senior lecturer john a. In some literature the name sensitivity is used for this.

In practice m is usually chosen to be greater than unity. Because of substantial path loss the received signal power from the satellites is relatively weak even below the thermal noise floor and as such is very sensitive to changes in the. In signal theory the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system where noise is defined as any signal other than the one being monitored. Only through clever processing algorithms can the actual signal be recovered.

In radio communication and electronics this may include thermal noise black body cosmic noise as well as atmospheric noise from distant thunderstorms and. Gps system signal sensitivity in this prelab we will examine the power of a gps signal received at your phone and compare it to the thermal noise floor of the phone that normally determines the lowest strength of signal that can be received thermal noise floor the level of background noise due to being above absolute 0 temperature. Abstract the global positioning system gps is a radio frequency rf navigation system that consists of transmitters on the satellites and receivers on the ground. This is because gps signals are very weak and operate below the thermal noise floor.
