1. A sensor system for continuous measurement of a glucose concentration in a host, the sensor system comprising:

  • a first sensor configured to be implanted in a host and configured to continuously measure a glucose concentration and generate a first signal, wherein the first sensor is associated with a first sensor accuracy during a first time period of a sensor session;

    a second sensor configured to be implanted in the host and configured to continuously measure a glucose concentration and generate a second signal, wherein the second sensor is associated with a second sensor accuracy during the first time period of the sensor session; and

    sensor electronics configured to determine a glucose concentration value based on at least one of the first or the second signal, wherein the sensor electronics are configured to integrate the first signal and the second signal by providing a distribution of weights associated with the first signal and the second signal and by according a first weight to the first signal and according a second weight to the second signal, wherein the distribution of weights among the first and second sensors is a function of time associated with the initiation of the sensor session.
