1. User equipment, comprising:
a motion sensor;
a temperature sensor;
a global navigation satellite systems (GNSS) receiver configured to receive a GNSS signal from a satellite, wherein the GNSS signal comprises a pilot channel; and
processing circuitry configured to
receive a first data input from the motion sensor indicative of a motion of the user equipment,
receive a second data input from the temperature sensor indicative of a temperature of the user equipment,
perform a coherent signal integration operation using the first data input and the second data input based on the pilot channel of the GNSS signal over a coherent period of time to generate a first resulting signal,
perform a non-coherent operation based on the first resulting signal to amplify the first resulting signal and generate a second resulting signal, and
output a position of the user equipment based on the second resulting signal.
