SYSTEM, METHOD, AND APPARATUS FOR COMPENSATING FOR IONOSPHERIC DELAY IN A MULTI CONSTELLATION SINGLE RADIO FREQUENCY PATH GNSS RECEIVER
First Claim
1. A method for a single Radio Frequency (RF) path receiver to compensate for ionospheric delay in multi constellation Global Navigation Satellite Systems (GNSSs), the method comprising:
- receiving a first signal at a first frequency from a first satellite in a first GNSS constellation;
receiving a second signal at a second frequency from a second satellite in a second GNSS constellation; and
calculating the ionospheric delay using the received first signal and the received second signal.

Abstract
Systems, methods, and apparatuses are provided for compensating for ionospheric delay in multi constellation Global Navigation Satellite Systems (GNSSs). In one method, a single Radio Frequency (RF) path receiver receives a first signal at a first frequency from a first satellite in a first GNSS constellation, receives a second signal at a second frequency from a second satellite in a second GNSS constellation, and calculates the ionospheric delay using the received first signal and the received second signal.

9. A single Radio Frequency (RF) path receiver that compensates for ionospheric delay in multi constellation Global Navigation Satellite Systems (GNSSs), the receiver comprising:
-
an antenna configured to receive a first signal at a first frequency from a first satellite in a first GNSS constellation, and to receive a second signal at a second frequency from a second satellite in a second GNSS constellation; a processor; and a non-transitory computer-readable medium having program instructions recorded thereon, the program instructions configured for the processor to calculate the ionospheric delay using the received first signal and the received second signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
