Enhancing Sensitivity to Reflected GNSS Signals

The method of any one of the preceding claims, further comprising:

• receiving a plurality of positioning signals from a plurality of satellites;
• determining a velocity of the receiver in motion using the plurality of positioning signals;
• and
• wherein performing coherent integration over the threshold duration of time to increase the signal to noise ratio for the particular positioning signal is further based on the velocity of the receiver.

The method of any one of the preceding claims, wherein identifying the particular positioning signal that reflected off the reflecting plane prior to reaching the receiver comprises:

• determining that the particular positioning signal reflected off a first reflecting plane and a. second reflecting plane prior to reaching the receiver;
• based on determining that the particular positioning signal reflected off the first reflecting plane and the second reflecting plane prior to reaching the receiver, determining a first reflected satellite position for the satellite that transmitted the particular positioning signal, wherein the first reflected satellite position is determined by reflecting the position of the satellite about the first reflecting plane;
• and
• based on determining the first reflected satellite position for the satellite, determining a second reflected satellite position for the satellite, wherein the second reflected satellite position is determined by reflecting the first reflected satellite position about the second reflecting plane.

A system comprising:

• a receiver;
• a processor configured to:
• identify a particular positioning signal that reflected off a reflecting plane prior to reaching the receiver, wherein the receiver is in motion;
• based on identifying the particular positioning signal, determine a reflected satellite position for a satellite that transmitted the particular positioning signal, wherein the reflected satellite position is determined by reflecting a position of the satellite about the reflecting plane;
• determine a direction vector to the reflected satellite position for the satellite;
• and
• based on the direction vector to the reflected satellite position, perform coherent integration over a threshold duration of time to increase a signal to noise ratio for the particular positioning signal.

A non-transitory computer-readable medium configured to store instructions, that when executed by a computing system, causes the computing system to perform functions comprising:

• identifying a particular positioning signal that reflected off a reflecting plane prior to reaching a receiver, wherein the receiver is in motion;
• based on identifying the particular positioning signal, determining a reflected satellite position for a satellite that transmitted the particular positioning signal, wherein the reflected satellite position is determined by reflecting a position of the satellite about the reflecting plane;
• determining a direction vector to the reflected satellite position for the satellite;
• and
• based on the direction vector to the reflected satellite position, performing coherent integration over a threshold duration of time to increase a signal to noise ratio for the particular positioning signal.
