Abstract
Techniques are provided for integrating GNSS measurements between two or more GNSS receivers. An example method includes determining an antenna baseline vector based on relative locations of a first antenna that is communicatively coupled to a first GNSS receiver and a second antenna that is communicatively coupled to a second GNSS receiver, determining a first position estimate and a first integer ambiguity resolution (IAR) status with the first GNSS receiver at a first time, determining a second position estimate and a second IAR status with the second GNSS receiver at approximately the first time, computing a horizontal offset value based on the antenna baseline vector and a difference between the first position estimate and the second position estimate, and generating the wrong fix indication in response to the first IAR status being fixed, the second IAR status being fixed, and the horizontal offset value being greater than a threshold value.
